| Family Scientific Name: | Linaceae | ||
|---|---|---|---|
| Family Common Name: | Flax | ||
| Scientific Name: | Linum lewisii | ||
| Common Name: | Lewis flax | ||
| Species Code: | LILE3 | ||
| Ecotype: | Piceance Basin Colorado | ||
| General Distribution: | Alaska to California and east to Minnesota in mixed grass, sagebrush, shadescale, pinyon/juniper, mountain brush and aspen communities. It can also be found in coniferous forests and openings. | ||
| Propagation Goal: | plants | ||
| Propagation Method: | seed | ||
| ProductType: | Propagules (seeds, cuttings, poles, etc.) | ||
| Time To Grow: | Weeks | ||
| Propagule Collection: |
Seed was collected in late June to mid July from the Piceance Basin area. It was collected when the capsules were dry and the seed was in the hard dough stage. Capsules were clipped from the plant and hand stripped. Seed was stored in paper bags at room temperature until seed was cleaned in the winter. 286,700 seeds/lb. (USDA, NRCS, University of Manitoba. 1997) 285,000 seeds/lb. (Hassell, et al. 1996) |
||
| Propagule Processing: | Seeds are cleaned by placing them in a Forsberg for approximately 20 seconds to thresh capsules. Then seeds are run through a two-screened fanning mill with varying fan speeds according to seed conditions. Top screen on the mill is a number 8, 1/14" screen on the bottom. Seeds are run several times until desired cleanness is achieved. | ||
| Pre-Planting Treatments: | No treatment is necessary for this species. Prior to planting a germination test was performed on the Lewis flax from Piceance Basin, it had 72 percent germination. | ||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Seed beds were firm and weed free. In August the seed was directly seeded into the ground. Seeds then laid dormant for the winter until they germinated in the spring. | ||
| Establishment Phase: | Sowing date: August Sowing/Planting Technique: 30-33 pure live seeds/ft. Seeded with a belt seeder at 0.25 inches depth. | ||
| Length of Establishment Phase: | Two growing seasons | ||
| Active Growth Phase: | Warm summer months | ||
| Length of Active Growth Phase: | Three months | ||
