Synonyms

  • Norta altissima (L.) Britton

Other Common Names

Jim Hill mustard, tall hedge-mustard, tumble mustard, tumbling mustard

General Distribution

Tall tumblemustard is native to Eurasia. It is widely naturalized throughout most of the world [106] including most of Canada and the United States. Tall tumblemustard does not occur in eastern Nunavut, western Newfoundland, or Alabama [75], and is rare in Florida [141]. It is mostly absent from Mexico, occurring only in the northern tip of Baja California Norte [137]. Tall tumblemustard was probably introduced in North America as a contaminant in imported crop seed [78]. Plants database provides a map of tumble mustard's distribution in the Untied States.

The biogeographic classification systems presented in the Appendix serve as a guide to where tall tumblemustard may be found. Precise distribution information is limited. Because it is so widespread, it is difficult to exclude many ecosystems as potential hosts of tall tumblemustard plants or populations; therefore, these lists are speculative.

Site Characteristics

On native soils in the Middle East, tall tumblemustard grows on desert foothills. Tall tumblemustard is a common agricultural weed in its native Asia and throughout most of the rest of the world [78]. In North America it is a common weed of old fields, roadsides, and other disturbed places [56,66,68,83,91,127] such as alluvial fans [146] and disturbed rangelands [123].

Soils

Tall tumblemustard grows in soils of all textures, and is common on sand [91]. It readily establishes on loose, highly disturbed soils such as rodent mounds [108,117], but can also grow on compacted soils. On a Mojave Desert restoration site in Antelope Valley, California, native seeded-in species did not establish on a highly disturbed site with compacted soil; however, tall tumblemustard colonized the site and established dense cover [55].

Elevation

Tall tumblemustard has been recorded at the following ranges

StateElevation
California< 8,200 ft (2,500 m) [62]
New Mexico5,000-7,000 ft (1,500-2,100 m) [83]
Nevada1,400-6,500 ft (430-2,000 m) [76]
Utah2,660-7,190 ft (820-2,410 m) [131]

Plant Communities

Tall tumblemustard occurs in disturbed plant communities throughout most of the United States and Canada. It is most invasive in the West, where it is common below the ponderosa pine (Pinus ponderosa) belt [123]. It occurs in sagebrush (Artemisia spp.), salt-desert shrubland, and pinyon-juniper (Pinus-Juniperus spp.) communities in the Great Basin [76]. On sagebrush steppe it commonly associates with other annuals in early seres. Near an abandoned oil-drill site in Wyoming, for example, it occurred in a big sagebrush (A. tridentata) community type with exotic Russian-thistle (Salsola kali) and cheatgrass (Bromus tectorum) and native annuals including common pepperweed (Lepidium densiflorum), desert goosefoot (Chenopodium pratericola), and sixweeks fescue (Vulpia octoflora) [2]. Herb sophia (Descurainia pinnata), clasping pepperweed (Lepidium perfoliatum), red brome (Bromus madritensis ssp. rubens), and medusahead (Taeniatherum caput-medusae) are other common annual associates [38]. In a big sagebrush-fourwing saltbush (Atriplex canescens) community in eastern Oregon, canopy cover of annuals exceeded 100%, with 42% cheatgrass, 10% cutleaf filaree (Erodium cicutarium), and 9% tall tumblemustard cover [50]. Associates of tall tumblemustard in Wyoming big sagebrush-broom snakeweed/Indian ricegrass (Artemisia tridentata ssp. wyomingensis-Gutierrezia sarothrae/Achnatherum hymenoides) of Utah included halogeton (Halogeton glomeratus), which was successionally replacing cheatgrass, and clasping pepperweed [84]. Blackburn and others [14] describe a tall tumblemustard-dominated disclimax community in west-central Nevada that occurs on highly disturbed rangelands.

Tall tumblemustard siliques and flowers.

Botanical Description

Tall tumblemustard is an exotic winter annual or biennial. It is the tallest species in the genus, reaching 4.9 feet (1.5 m) or more in height. Growth form is rounded and freely branching from a single basal stem. Leaves are 0.4 to 7.9 inches (1-20 cm) long, becoming smaller up the stem. The inflorescence is a raceme of perfect flowers. The fruit is a 2- to 3.9-inch-long (5-10 cm), narrow silique with 120 or more small (~1 mm in length), wingless seeds [56,62,88,100,123,127,130,131]. Tall tumblemustard has a thick taproot [123,142]. Maximum root depth of plants in Wyoming averaged 17 inches (43 cm) over 2 years, ranging from 9.1 to 23 inches (23-58 cm). Of 7 annuals species excavated, only Russian-thistle grew longer roots [2].

Raunkiaer Life Form

  • Therophyte [101]

Seasonal Development

Tall tumblemustard germinates in winter or early spring, before most associated herbaceous species have started growth [2]. It develops a rosette after the cotyledon stage, then bolts [2,136]. The flowering period is lengthy. A single plant typically bears numerous racemes that flower sequentially up the pedicel. The flowers mature quickly, with relatively few in bloom at once. The lower leaves usually dry out around flowering time without affecting flower production [123]. Phenological events by region are as follows:

Regeneration Processes

As an annual, tall tumblemustard reproduces solely from seed.

Pollination and Breeding System

Pollination is by insects [61]. Mustards (Brassicaceae) are cross-pollinated. Selfing also occurs [61].

Seed Production

Tall tumblemustard is a prolific seed producer. A single plant can produce up to 12,500 siliques and 1.5 million seeds [24,88].

Seed Dispersal

Seeds disperse when the dead, dried parent plant breaks at the stem base and tumbles or slides across the ground by wind or other movement [88,123,143]. The fruits are tough and shatter slowly, so only a few seeds at a time are released. Consequently, the dried plant may disperse seeds throughout fall and winter, across many miles [78,88,123,136]. Animals disperse seeds when the wet, mucilaginous seed coat sticks to feathers or fur [150]. Machinery can pick up branches and whole plants, transporting seeds hundreds to thousands of miles. Tumble mustard's initial expansion westward was probably facilitated by railroad cars. One of the species' common names, Jim Hill mustard, comes from the name of the early railroad magnate [88,130].

Seed Banking

Tall tumblemustard builds up a long-term seed bank [50,52,63,147,153]. Seed stored over 40 years has germinated in the laboratory (review by [134]). It is unclear how long seed remains viable in natural seed banks. In a Virginia pasture experiment, tumble mustard seed buried 8 inches (20 cm) deep in pots showed 10% germination after 2 years' burial, 21.5% after 4 years, 79% after 7 years, and 0% germination after 17 and 22 years [52].

Tumble mustard's soil seed bank is dynamic, reaching greatest seasonal density in fall and greatest year-to-year fluctuation in wet years. In Yellowstone National Park, mean seed bank density of tall tumblemustard (based on number of emergents in soil samples) was 53 plants/m2 [23]. A degraded big sagebrush-spiny hopsage/Thurber needlegrass (Grayia spinosa/Achnatherum thurberianum) community near Reno, Nevada, showed seasonal and spatial variation in density of tumble mustard seed as follows [147]:

Germination

Tall tumblemustard seeds become mucilaginous upon wetting, which helps them retain moisture. Seeds can germinate on the seedbed surface without litter or soil covering [78,147]. In the absence of cheatgrass, tall tumblemustard may show better germination and establishment with litter; however, when cheatgrass is present in the seed bank, cheatgrass tends to outcompete tall tumblemustard [147]. Tall tumblemustard seeds are immediately germinable at temperatures from 32 to 68 degrees Fahrenheit (0-20 °C), with no stratification requirement. Best germination occurs on fine-textured soils with temperatures around 50 degrees Fahrenheit (10 °C) [150]. Near Reno, seeds showed best germination in May [147]. Germination rates are generally good, but irregular. In southern Idaho, tall tumblemustard seed stored for a year in an unheated shed showed 93% germination [67]. Seed lots collected in northern Nevada and northeastern California showed irregular germination; they did not all germinate at 1 time under "ideal" laboratory temperature and moisture conditions. Seed lots were collected over 4 consecutive years. Germination continued for 12 weeks, with some seeds germinating in their 2nd year [150]. Frequency of tall tumblemustard in a black sagebrush (Artemisia nova) community of west-central Nevada was highest in a year of above-average annual precipitation. Mean frequency (% and 1 standard error (SE)) varied as follows [151]:

Average ppt

Dry year
(1989, no April ppt; annual ppt not available)
Wet year
(1986, 225 mm annual ppt)
5 (0.9)010 (0.8)

Tall tumblemustard seeds show some ability to withstand short-term high temperatures. Seeds collected from Yellowstone National Park showed equal emergence (53/m2 ) from soil samples at room temperature and samples heated to 120 degrees Fahrenheit (50 °C). Emergence dropped to 13/m2 at 210 degrees Fahrenheit (100 °C) and 0 at 300 degrees Fahrenheit (150 °C) [23].

Seedling Establishment and Growth

Tall tumblemustard shows best establishment on mineral soil under an open canopy. In the Reno study discussed above, Young and Evans [147] found better tumble mustard establishment between shrubs compared to under shrubs. They attributed this to better litter and soil moisture conditions for cheatgrass under shrubs, where cheatgrass outcompeted tumble mustard.

Tall tumblemustard seedlings grow rapidly. In uncrowded stands, they form large rosettes before bolting [2]. Emergence and establishment are enhanced by uneven microtopography, with tall tumblemustard establishing best in pits and furrows [55,145,149].

As annuals, tall tumblemustard populations fluctuate in size depending upon climate and other factors [94,103]. In a big sagebrush/bluebunch wheatgrass (Pseudoroegneria spicata) community of eastern Washington, tall tumblemustard was absent from study plots in 1977, a drought year. Its mean biomass was 0.77 g/m2 in 1978, when precipitation was average [35]. In years of above-average precipitation, tall tumblemustard and other annuals can produce considerable biomass. With disturbance, the annuals may invade areas where they were sparse or absent before the frequent rains [37].

Vegetative Reproduction and Regeneration

Tall tumblemustard does not reproduce or regenerate vegetatively.

Successional Status

Tall tumblemustard requires an open to light canopy [69,124,147], and is most common in early stages of succession [2,22,25,31,96].

Tall tumblemustard occurrence in early sagebrush steppe succession is well documented. In big sagebrush of Wyoming, for example, tall tumblemustard occurred 2 and 3 years after disking near an abandoned oil drilling site [2]. A classic seral continuum is described by Piemeisel [96] and other authorities [40,115,122] where Russian-thistle pioneers on sagebrush steppe disturbed by fire or other means. Tall tumblemustard establishes next, followed by tansymustard (Descurainia spp.) and cheatgrass. Medusahead, Scotch thistle (Onopordumacanthium), and other species may extend or alter the classic continuum [40,41]. A 20-year study in southern Idaho showed old-field succession on former big sagebrush steppe was initially dominated by Russian-thistle, tumble mustard, and tansymustard. An increase in cheatgrass and bottlebrush squirreltail (Elymus elymoides) followed; after that, there was a temporary increase in mustards and a decrease in Russian-thistle. The community eventually stabilized as a cheatgrass-bottlebrush squirreltail cover type [64]. A similar pattern occurred in sagebrush steppe of Washington, where tall tumblemustard codominated recently disturbed sites along with Russian-thistle, prickly-lettuce (Lactuca serriola), and bur ragweed (Ambrosia acanthicarpa). Cheatgrass dominated slightly older seres such as old fields [15]. Some annual-dominated communities may be stable [64]. On the Atomic Energy Commission's Hanford Reservation, Washington, old fields have supported cheatgrass-tumble mustard-tansymustard communities for 30 or more years [27]. Tall tumblemustard is not highly invasive in undisturbed sagebrush communities. In lightly grazed and ungrazed sites in a big sagebrush/bluebunch wheatgrass community of eastern Washington, tall tumblemustard established in severely trampled areas where cattle congregated (watering troughs and fencelines), but did not invade other portions of the otherwise lightly grazed site or the ungrazed site [102].

Other communities: Tumble mustard's successional role is less well documented in plant communities other than sagebrush. Similar to its pattern of occurrence in early seral sagebrush, a few studies show early tumble mustard invasion in disturbed communities followed by tumble mustard's successional replacement by perennials. In western wheatgrass-buffalo grass-blue grama (Pascopyrum smithii-Buchloe dactyloides-Bouteloua gracilis) communities of Nebraska, tall tumblemustard occurs in wetland succession at the edges of ponds. On upland sites it occurs on deep, poorly bound, wind-deposited soils along with common sunflower (Helianthus annuus), prairie sunflower (H. petiolaris), and lambsquarters (Chenopodium album) [74]. In a shadscale community of south-central Idaho, tumble mustard, halogeton, clasping pepperweed, and cheatgrass invaded after a combination of drought and root-mining mealybugs killed most of the overstory shadscale. Six years after the shadscale dieback, the site was dominated by halogeton and annual weeds. Grasshopper populations were high the 7th year following the dieback, so halogeton, tumble mustard, and other annuals maintained dominance with grasshopper grazing. Shadscale, gooseberryleaf globemallow (Sphaeralceagrossulariifolia), and native perennial grasses gained dominance the next year, when the drought ended and the insect populations declined [112].

Tall tumblemustard is nonmycorrhizal [12,46]; therefore, it can colonize sterile sites or sites undergoing primary succession.

Immediate Fire Effects

While in the rosette stage, tall tumblemustard may be top-killed by fire. If the root crown is not damaged, tall tumblemustard rosettes can sprout  new basal leaves from the root crown. As an annual with a single stem, tall tumblemustard lacks adaptations for regrowth once it has bolted, and plants burned after the rosette stage are killed [51]. Research on fire's impact to the seed bank is lacking as of this writing (2003), but fire probably has little effect on tall tumblemustard seed populations. Tall tumblemustard has tiny seeds [56,62,88,100,123,127,130,131] that easily fall into fire-safe microsites such as soil crevices [55,145,149]. While fire is likely to kill some seed, its overall effect to the tall tumblemustard seed bank is probably negligible.

Postfire Regeneration Strategy

  • Ground residual colonizer (on-site, initial community)
  • Initial off-site colonizer (off-site, initial community)
  • Secondary colonizer (on-site or off-site seed sources) [116]

Fire Adaptations

Tall tumblemustard establishes from soil-stored seed after fire [41,45,110,138]. Wind, machinery, and animal transport from off-site may provide additional sources of seed [146] or introduce tall tumblemustard on burns where it was not already present in the soil seed bank. Fire creates conditions favorable for tall tumblemustard establishment (bare soil, open canopy, reduced growth interference) [97]. As a shade-intolerant, invasive species, tumble mustard can thrive in early postfire environments [26,71,72,140].

Plant Response to Fire

Tall tumblemustard establishes from soil-stored seed and seed blown or transported in after fire [41,45,110,138]. It is most frequent on early seral burns [26,72]. For example, in a Idaho fescue-prairie Junegrass (Festuca idahoensis-Koeleria macrantha) community of northeastern Oregon, tumble mustard and mountain tansymustard (Descurainia incana) pioneered on severely burned sites, but were absent by the 5th postfire year [72]. In Colorado pinyon-Utah juniper (Juniperus osteosperma) stands of west-central Utah, tall tumblemustard occurred on 6- and 11-year-old burns, but not older burns [10].

Tall tumblemustard cover (%) on burned and unburned plots after a June 1977 fire on Mt. Sentinel in Missoula, Montana, is shown below. The cover type is rough fescue (Festuca altaica)-Idaho fescue-bluebunch wheatgrass mountain grassland [4].

Another study of plant cover the after same fire showed similar effects. Although tall tumblemustard cover (%) was low on burned and unburned plots, tall tumblemustard increased with fire. Measurements were taken in November 1977, 5 months after the Mt. Sentinel Fire [85]:

One year after a July wildfire in a ponderosa pine/bluebunch wheatgrass community of British Columbia, tall tumblemustard established as follows [71]:

Frequency (%)Basal cover (%)Aerial cover (%)

0.020.00.0trace0.00.2±4.80

Although fire creates the open canopy and bare mineral soil that favors tall tumblemustard establishment, tall tumblemustard is not an obligate "fire follower."" Any area with bare ground, open sunlight, and a seed source is vulnerable to tall tumblemustard invasion [70].

Burning does not always increase tall tumblemustard cover [114,133,148]. In his classic study of postfire succession of tall tumblemustard and other exotics in big sagebrush, Piemeisel [96] wrote "the mere statement that a field has been burned is not sufficient information to foretell what the effect will be on the succeeding plant cover.

Frequency of tall tumblemustard on 50 × 50-cm plots burned under prescription on 15 September 1983 on the Shoshone District, Idaho BLM, was 8.8% in autumn 1982 (prefire), 1.3% in 1983 (postfire), 23.8% in 1984, and 86.3% in 1986. Burning was conducted in threetip sagebrush (Artemisia tripartita) and successfully reduced persistent litter. Macrobiotic soil crusts began recovery in postfire year 3. Burning conditions were [19]:

Temperature70° F
Relative humidity14%
Windspeed5-8 mph
Live sagebrush moisture92%
Soil moisture4%

Fall and spring prescribed burning in a basin big sagebrush community in east-central Oregon had no significant effect on tall tumblemustard frequency in postfire year 1 or 2 [107]. See the Research Project Summary of this work for more information on fire effects on tall tumblemustard and 60 additional forb, grass, and woody plant species.

The FEIS Research Project Summary, Nonnative annual grass fuels and fire in California's Mojave Desert, provides information on prescribed fire and postfire response of tall tumblemustard and other plant community species.

Fire Regimes

Introduced species can alter the probability of occurrence of fire, the rate of fire spread, and the intensity of fire in an ecosystem [30]. The degree of change and impacts on native ecosystems vary with differences in species composition and structure of invaded plant communities [17,113]. Historic fire regimes in big sagebrush/bunchgrass ecosystems, where tumble mustard is common, are variable. Fire return intervals range between 10 and 70 years [7,18,87,92,126,149]. The introduction and increasing dominance of cheatgrass has changed the seasonal occurrence, frequency, and size of wildfires in these ecosystems, thus altering successional patterns [13,95,132,135,144]. Tumble mustard invaded the western Unites States shortly before cheatgrass [78,88]. There is no evidence suggesting that tall tumblemustard alone has altered historic fire patterns in sagebrush steppe, but interactive effects of tumble mustard and cheatgrass are largely unstudied. Further research is needed on the impacts of tall tumblemustard invasion in sagebrush steppe and other ecosystems where weeds have drastically altered fire regimes.

Because tall tumblemustard is widespread, it is difficult to exclude many ecosystems as potential hosts of tall tumblemustard plants or populations. The following table provides some fire regime intervals for plant communities where tall tumblemustard may be important.

Fire Management Considerations

Fire as a Control Agent

There are no published studies on using fire to control tall tumblemustard, but given tumble mustard's positive response to increased light and nutrients and open ground, fire alone is unlikely to provide control of tall tumblemustard. If tall tumblemustard is already onsite in the seed bank, or as a few plants, fire is likely to increase the species' importance in the early postfire community.

Federal Status

None

Other Status

None

Importance to Wildlife and Livestock

All classes of livestock consume minor to moderate amounts of tall tumblemustard, depending upon availability of other, more palatable forage [69]. For example, Rocky Mountain mule deer consume minor amounts of tall tumblemustard throughout the growing season [81]. Black-tailed jackrabbit in southern Idaho ate minor amounts of tall tumblemustard in summer [43]. Tall tumblemustard was a minor item in the spring diet of Townsend's ground squirrels on the Arid Land Ecology Reserve of Washington [72,73].

Palatability and Nutritional Value

Tall tumblemustard is palatable to livestock when young. Palatability of mature plants is low. The seeds are unpalatable to livestock [123]. Palatability of tall tumblemustard for livestock and wildlife has been rated as follows [33]:

Other Uses

Tall tumblemustard is a honeybee and butterfly plant [75]. It helps bind fine-textured soils [88].

Native Americans made meal from ground tumble mustard seeds. The greens can be used in salads [88].

A field of tall tumblemustard in southwestern Idaho.

Tall tumblemustard is one of the most invasive nonnative forbs in the Great Basin [98,150]. Allen and Knight [2] suggest tall tumblemustard's success as an invasive weed is due to more effective seed dispersal compared to native herbaceous perennials, morphological plasticity in response to density stress (tall tumblemustard plants are short with shallow roots when crowded, but still produce numerous seeds), and earlier germination and more rapid seedling growth compared to native herbs.

Range

Tall tumblemustard is uncommon on good- to excellent-condition rangeland, and is an indicator of deteriorating rangeland quality [69]. Rangelands dominated by tall tumblemustard and other annuals show poor productivity compared to ranges dominated by perennial grasses [94]. Tall tumblemustard increases in response to grazing [93]. In mountain grasslands of central Utah, it was among the most important invaders on overgrazed plots in bluebunch wheatgrass-Sandberg bluegrass (Poa secunda) along with cheatgrass, Russian-thistle, cutleaf filaree, and yellow salsify (Tragopogon dubius) [22]. Daubemire [31] described tall tumblemustard as a seral species that benefits from grazing by release from the competition of more palatable species, but declines in frequency when successionally replaced.

Cropland

Tall tumblemustard is a serious crop weed [123,154]. Hay or grain infested with tall tumblemustard seeds is unpalatable to cattle and horses [123]. Tall tumblemustard is an alternate host for several crop diseases including potato leafroll virus [47,121].

Tall tumblemustard absorbs soil contaminants such as heavy metals and radioactive waste. Due to its tumbling habit, it may spread the contaminants to other sites [129].

Prevention

Since tall tumblemustard is an early seral species, minimizing soil disturbance and seed dispersal and maintaining a healthy plant community is the best way to prevent establishment of tumble mustard [28]. Anderson and Inouye [3] found sagebrush steppe ecosystems of southeastern Idaho were statistically more resistant to invasion by tall tumblemustard and other exotic annuals when cover of native species was high (R2=0.16, P=0.008).

Control

Tall tumblemustard does not usually persist in late-seral communities and may not require special control measures. Canopy closure, litter accumulation and/or growth interference from later-successional species tend to exclude tall tumblemustard over time.

Fire

See Fire Management Considerations.

Physical and Mechanical Control

Small infestations of tumble mustard can be controlled by hand pulling rosettes in the fall or early spring [28].

Biological Control

In free-choice trials, tall tumblemustard was the most palatable of 18 early successional annuals and biennials to native and introduced slug species [21].

Chemical Control

Herbicides are effective in gaining initial control of a new invasion or a severe infestation, but are rarely a complete or long-term solution to weed management [20]. Herbicides are more effective on large infestations when incorporated into long-term management plans that include replacement of weeds with desirable species, careful land use management, and prevention of new infestations. Control with herbicides is temporary, as it does not change those conditions that allow infestations to occur [152]. See the Weed Control Methods Handbook for considerations on the use of herbicides in natural areas and detailed information on specific chemicals.

Tall tumblemustard is susceptible to broadleaf herbicides including 2,4-D, MCPA, bromoxynil, atrazine, and chlorsulfon [1,36,77,119]. Phenoxy herbicides such as 2,4-D and MCPA provide best control (90-99%) [1,77,119].

Integrated Management

Land management practices that promote later-successional species can exclude tall tumblemustard from most plant communities [28]. Managers are encouraged to use combinations of control techniques that are appropriate to the site objectives, desired plant community, available resources, and timing of application. For information on integrated weed management without herbicides, see the Bio-Integral Resource Center (BIRC) website.
