| Common Name: | Alpine Felwort | ||
| Ecotype: | Subalpine meadow with dwarf willows and ericaceous shrubs. Near Hatcher Pass, Talkeetna Mtns., Alaska | ||
| General Distribution: | Southcentral through SE Alaska, southward through BC and AB to the western states. | ||
| Propagation Goal: | plants | ||
| Propagation Method: | seed | ||
| ProductType: | Container (plug) | ||
| Time To Grow: | 0 | ||
| Target Specifications: | Firm root plug, multiple true leaves. | ||
| Propagule Collection: | Seed pods are hand collected in early to mid September. | ||
| Propagule Processing: | Pods are dried, split, and seed is hand sieved and air-blown. | ||
| Pre-Planting Treatments: | No pretreatment is needed if seed is Fall-sown. Otherwise, 90-120 days of cold, moist stratification at 34-38ø F. is needed before sowing. | ||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Seed is sown in the Fall in facultativesoil mix in Spencer-Lemaire rootrainers and stored in a sheltered area where it is exposed to outside winter temperatures. Trays are moved to the greenhouse in Spring. | ||
| Establishment Phase: | Germination was fairly rapid and even over a 3-week period after the trays were moved to the greenhouse. Germination exceeded 60%. | ||
| Length of Establishment Phase: | 3 weeks | ||
| Active Growth Phase: | Plants remained in the greenhouse until true leaves were well established. | ||
| Length of Active Growth Phase: | 4 weeks | ||
| Hardening Phase: | Plants are removed from the greenhouse to a sheltered outside area for hardening. | ||
| Length of Hardening Phase: | 1 month | ||
