Machaeranthera
tanacetifolia or Aster tanacetifolius, commonly named Prairie
Aster, Tahoka Daisy, Tanseyleaf, and
Tansy Aster is a
hardy upright and sprawling annual wildflower native to the mid-western United
States with dense, compact leaves that deeply divide into narrow segments.
Machaeranthera tanacetifolia flowers are simple and beautiful with deep purple
petals and a brilliant yellow center. Prairie Aster or Tahoka Daisy is an
excellent choice for hard-to-maintain areas and prefers sandy or gravelly soil
in full sun. Periodic watering will encourage blooms. Prairie Aster
seeds germinate better after receiving 2 weeks cool, moist pretreatment.
If seeds are to be sown indoors, store them in a moistened medium in the
refrigerator for 2 weeks prior to sowing or sow outdoors in
early spring.

Uses
Restoration/reclamation:
Bigelow’s tansyaster is used as a forb component for restoration and wildlife
enhancement projects. Once established it exhibits extreme drought tolerance. As
an early seral species, it competes with undesirable non-native species such as
cheatgrass (Bromus tectorum) and knapweed species (Centaurea spp.). Its tall
stature and showy flowers provide structural diversity in a mix for wildlife. As
an early colonizer for disturbed sites, it may be used for erosion protection
for restoration projects post-wildfire, and reclamation projects. It can be
planted to enhance species diversity in rangeland; however, it is not noted as
having value as forage for livestock (Ogle et al 2011).

Pollinator
A variety of generalist bees, such as honey and leaf-cutter bees, which are
active late in the summer or early autumn, utilize the prolific blooms of
Bigelow’s tansyaster (Cane, 2012).
Status
Please consult the PLANTS Web site and your State Department of Natural
Resources for this plant’s current status (e.g., threatened or endangered
species, state noxious status, and wetland indicator values).
Description
General: Aster Family (Asteraceae). This genus has been recently circumscribed
to Dieteria, to better incorporate the current understanding of the complex
evolutionary history (Cronquist et al 1984;Turner 1987; Hartman 1990; Morgan
2009; Morgan and Hartman 2003; Stevens 2001; and Weber and Wittmann, 2001).
Bigelow’s tansyaster is a native biennial to short-lived perennial with deep
violet to blue-white colored flowers. Plants are 1 to 3 feet tall (15cm to 90cm)
and arise from a taproot. Cauline (stem) leaves are 0.4 to 3 inches long (1cm to
7.5cm) and 0.30 in. (1.5mm to 8mm) or less in
width, lance- to oblanceolate-shaped with sharply toothed margins. Flower heads
are subtended by overlapping rows of bracts (phylliaries) with curved tips which
are green for at least half of the length of the phylliary. The flower stalks,
(peduncle) and bracts are covered with sticky glandular hairs (trichomes). The
pappus attached to the achene is off-white and there are 1,283,000 seeds per
pound (Wilson 2012). Blooms from July to October.
Bigelow’s tansyaster (Machaeranthera bigelovii) and hoary tansyaster (Machaeranthera
canescens) are challenging to distinguish due to overlapping habitats and
hybridization and the many varieties of M. canescens. Weber and Wittmann (2001)
distinguish between the two species as follows:
M. bigelovii: Presence of glandular trichomes on both the peduncles and
phylliaries. Phylliaries with green tips equaling or exceeding the colorless
base (Figure 4).
M. canescens: Well-developed glandular trichomes absent from peduncles.
Phylliaries with a relatively short green apex (Figure 5), (Schneider 2004).
Ethnobotany
Machaeranthera ssp. have been utilized by Native American Tribes for a variety
of purposes from a stimulant to gastrointestinal aid to respiratory aid. The
flowers used to make necklaces (Native American Ethnobotany, 2012). Plants were
used by Navajo Indians for nose and throat troubles (Moerman, 1998).
Distribution:
According to Morgan and Hartman (2003), of the three recognized varieties of
Dieteria bigelovii only Dieteria
bigelovii var. bigelovii, (Bigelow’s tansyaster), occurs in

the Southern Rocky Mountain region of Wyoming, Colorado and New Mexico (Welsh
2003). While Bigelow’s tansyaster is very similar to the hoary tansyaster, it is
much more restricted to habitat and range (Schultz 1987, Welsh 2003, Turner
1987).
Habitat:
Bigelow’s tansyaster is common in plant communities such as meadows, open areas,
subalpine coniferous forests, oak woodlands, grasslands, creosote bush or
sagebrush scrublands, often found along streams and roadsides (Hartman 2012). In
the fall months, vast flower displays of Bigelow’s tansyaster may be observed in
foothill fields and along roadsides.
Adaptation
Bigelow’s tansyaster is adapted to fine to coarse textured soils with a pH of
6.0 to 8.5 (USDA Plants Database; Tilley et al, 2010). Bigelow’s tansyaster
requires full exposure to sunlight, and a minimum 6 inch rooting depth. The
species is commonly found in areas receiving 6 to 18 in. (15cm to 45cm) of
annual precipitation at 7,500 to 11,500 feet (2300m to 3200m) in elevation.
Establishment
“Loring (2012) observed 80% to 90% typical germination from fresh seed at 15 ° C
for 21 days,” Hall (2012) noted 93% and 98% seed viability from Tetrazolium
tests.
For conservation and restoration projects seed should be drilled or broadcast
seeded in late fall into a firm, weed-free seed bed at a depth of 0 to 6 mm (0
to 0.25 in.) To establish a solid stand for seed production, target delivery of
20 to 30 pure live seeds (PLS) per square foot, seed at a rate of 2 lbs (0.9 kg)
PLS per acre. If seeding as part of a mix, adjust seeding rate to the desired
percentage of the

mixture. Broadcast seedings should be followed with a culti-packer to ensure
good seed to soil contact. For establishment of fields for seed production, use
irrigation for the first two weeks to establish plants from seed, conduct
seeding in spring, with monsoonal moisture in summer, or in fall (Swift, 2012).
Seed should be mixed with a carrier such as rice hulls to assist seed flow
through seeding equipment. When calculating rice hull amounts based on seed
bushel weights, it is important to determine the condition of the seed. Hoary
tansyaster seed which has not had the pappus removed has a bushel weight of
approximately 3 lb/bushel (Tilley, et al 2010).
Management
When planted in a wildlife habitat or reclamation seeding, use Bigelow’s
tansyaster as a quick establishing species that provides competition to
nonnative weedy species. As longer-lived perennials become established,
Bigelow’s tansyaster will become a minor component in the established plant
community; therefore, management should be based on other key species. Defer
grazing on seeded lands for at least two growing seasons to allow for full stand
establishment.
Pests and Potential Problems
Moth caterpillars from the genus Cucillia were observed on observational plots
of M. canescens at Aberdeen, Idaho. These were seen eating flower heads, but did
not appear to do extensive damage to the plots or decrease seed production
significantly (Tilley et al, 2010). Caterpillars were also observed eating
flower heads on production plots of M. bigelovii, in the San Luis Valley of
Colorado, however, the species of caterpillar was not identified (Swift, 2012).
Seed and Plant Production
Seed production fields of Bigelow’s tansyaster can be planted into weed barrier
fabric at 23 to 46 cm (9 to 18 in.) spacing (Tilley et al 2010). Seed should be
planted in late fall into slightly roughened soil and then lightly packed. For
seed production and under irrigation, seed may be planted in the spring with row
spacing for between row cultivation. After establishment no additional moisture
is required and plants are extremely drought tolerant (Swift, 2012). When using
irrigation, Swift 2012, noted the presence of caterpillar infestations on the
flowers observing them to be absent when irrigation is not utilized.
Seed can be harvested by hand, direct combined, or by using a vacuum harvester
(Bair and Tilley, 2010) beginning mid- to late October. Vacuum harvesters allow
multiple, non-destructive harvests to take place as seed matures. Seed can be
cleaned by sifting collected materials over ˝ inch hardware cloth to separate
seed from stems and flower heads. Using this method, it is possible to collect
seed of high enough quality that additional processing may not be necessary.
Seed processed in this manner will have an intact pappus and fair to moderate
purity; however, when mixed with a carrier such as rice hulls, the seed flows
well through grain and no-till drills and other seeding equipment. Seed harvests
of experimental plots of M. canescens, yielded approximately 200 lbs of clean
seed per acre (Tilley et al, 2010).
Weed control efforts should begin prior to planting. Planting into a weed-free
seed bed, or using weed barrier fabric greatly reduces management inputs. Weeds
can be controlled using pre-emergent herbicides and by hand rouging. Weedy
grasses can be controlled with selective herbicides (Tilley et al, 2010).
Always read and follow label and safety instructions for each control method.
USDA-NRCS does not guarantee or warranty any products or control methods named,
and other products may be equally effective.
As with M. canescens, Bigelow’s tansyaster is a difficult species to clean. Seed
is small with a flexible pappus that is not easily removed. Tilley et al 2010,
describe “hammer-milling removes some of the pappus, but mostly results in
creating a mat of pappus hairs, seed, and inert matter. The USDA Forest Service
at the Bend, OR Seed Extractory uses a Westrup Model LA-H laboratory brush
machine with a #40 mantel at a speed of 3 to dislodge seed from the flower heads
and remove the pappus. The gate is left completely open to allow the seed to
move quickly through the machine and avoid damaging the achenes.” This is
followed by air-screening (Barner, 2009
