Barestem Biscuitroot seeds - 0.5 oz

$21.00

Lomatium nudicaule - seeds - 0.5 oz


Seeds are from the Confederated Tribes of Grand Ronde Plant Materials Center.


Barestem Biscuitoot is a culturally significant plant.


Description: Carrot family (Apiaceae). Barestem biscuitroot is a perennial forb arising from a stout taproot. The plants reach a mature height of 20 to 45 cm (8 to 18 in).


Habitat: Barestem biscuitroot is found in dry, open to sparsely wooded places in lowlands to middle elevations (Cronquist et al 1997). It is often found growing in sagebrush, pinyon-juniper, ponderosa pine, and mountain brush communities in the Intermountain West (Welsh et al 2003).


Adaptation: Barestem biscuitroot grows in sandy soils (Walker and Shaw 2005) in areas receiving 350 mm (14 in) or more mean annual precipitation.


Establishment: Biscuitroot species can be broadcast or drill seeded (Walker and Shaw 2005). Best results can be obtained from dormant fall seedings into a firm, weed-free seed bed. Seed should be placed at a depth of 0.6 to 1.2 cm (0.25 to 0.5 in) and packed to ensure good seed to soil contact.


Management: Arrowleaf balsamroot should be used as a minor component of seed mixtures. Management strategies should be based on the key species in the established plant community. Grazing should be deferred on seeded lands for at least two growing seasons to allow for full stand establishment (Ogle and others, 2011; Stevens and Monsen, 2004). Once established, barestem biscuitroot is very competitive against weeds due to its deep taproot.

Perideridia gairdneri - seeds - 0.5 oz


Yampah is a culturally significant plant. Seeds are from the Confederated Tribes of Grand Ronde Plant Materials Center.


Perideridia gairdneri is a species of flowering plant in the family Apiaceae known by the common names common yampah, Gardner's yampah and Squaw root. It is native to western North America from southwestern Canada to California to New Mexico, where it grows in many types of habitat. It is a perennial herb which grows to around .6–1 metre (2.0–3.3 ft).[1] Its slender, erect stem grows from cylindrical tubers measuring up to 8 centimeters long. Leaves near the base of the plant have blades up to 35 centimeters long which are divided into many narrow, subdivided lobes. Leaves higher on the plant are smaller and less divided. The inflorescence is a compound umbel of many spherical clusters of small white flowers. These yield ribbed, rounded fruits each a few millimeters long.


The entire plant is edible, but caution should be maintained as it has a similar appearance to the carrot family's deadly water hemlock and poison hemlock.[1] It was an important food plant, even a staple food, for many Native American groups.
