Description
General: Slender, glabrous perennial from a tuberous-thickened, edible, usually solitary root, the solitary stem 4-12 dm. tall. Leaves: Leaves several, well distributed along the stem, the blade once pinnate or ternate; the ultimate segments elongate and narrow. Flowers: Inflorescence of terminal and 1-several lateral compound umbels, the umbels 2.5-7 cm. wide; rays up to 6 cm. long at maturity; involucre of a few, narrow bracts; involucre of bristly bracelets, or wanting; calyx teeth well developed; flowers white. Fruit: Fruit glabrous, sub-orbicular, 2-3 mm. long and wide, with prominent ribs.

Occurs from southern B.C. to southern California and east to Saskatchewan, South Dakota and Colorado -cnlm pages
Habitat
Perideridia gairdneri prefers well-drained, nitrogen medium soils. It tolerates slightly acid to mildly alkaline soils. It is very shade intolerant. It is a climax species in drier sites, and is found in the meadow communities in Garry oak ecosystems. Grows from low to middle elevations.

Propagation
Hand collect seeds in August when seeds have turned brown and are easily stripped off inflorescence into paper bags. Store seeds in sealed containers at 5º C. Seed will retain viability for up to five years. Sow seeds in fall and allow natural stratification, or sow stored seeds in the spring after six to eight weeks of cold, moist stratification.
The Seed
Peridendia gairdneri
PEGA
Seed sample from 2011
Features
Average Measurement: 2.3 x 1 x 1
Measurement Range: L: 1.5 – 3, W: 0.8 – 1.1, D: 0.75 – 1.3
Latitudinal Cross Section: ovate
Longitudinal Cross Section: elliptical
Shape: Seed schizoid, flat on one plane, and rounded on the opposite plane. Lots of irregularity in shape.
Color: Various shades of green and brown. Hilum usually white. Some seeds have pink from remnant flower structure at apex opposite hilum.
Surface: Seeds have five ridges on outer seed face that run from hilum to opposite apex longitudinally. Inner seed face has one white rib that bisects the seed face.
Basic Explanations and Assumptions:
The dimensions for the seeds are length x width x depth. The location of the hilum is used as the base of the seed, and the length is measured from hilum to the opposite apex. Where a style is present, the length is measured from the hilum to the bottom of the style. Width is measured at a right angle to the length at the widest part. Depth is measured at a right angle to the intersection of height and width lines.
Measurements included are the mean average for each measurement of ten separate seeds.
All measurements in millimeters unless otherwise noted.
