| Family Scientific Name: | Rosaceae | ||
|---|---|---|---|
| Family Common Name: | Rose Family | ||
| Scientific Name: | Potentilla hippiana Lehm. | ||
| Common Name: | woolly cinquefoil | ||
| Species Code: | POHI6 | ||
| Ecotype: | Mine impacted (acidic and heavy metal contaminated) bluebuch/rough fescue range type | ||
| General Distribution: | P. hippiana occurs from the Rocky Mountains of Alberta to New Mexico and Arizona, east to Saskatchewan, the Dakotas, and Nebraska. | ||
| Propagation Goal: | plants | ||
| Propagation Method: | seed | ||
| ProductType: | Container (plug) | ||
| Stock Type: | 7 cubic inch Cone-tainer | ||
| Time To Grow: | 0 | ||
| Target Specifications: | Fully rooted containers for field transplanting. | ||
| Propagule Collection: | Seed wild collected in August by cutting flower heads off with a sickle. | ||
| Propagule Processing: | Seed knocked out of capsule by running collected plant material through a hammer mill and cleaned using a small fan mill (Office Clipper). | ||
| Pre-Planting Treatments: | Seeds planted 0.25 inch deep in 7 cubic inch Cone-tainers containing Sunshine Mix #1 soil media, watered-in, and placed in walk-in cooler maintained at 36F (2C) for 30 days. | ||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Following cold stratification, Cone-tainer trays are moved to a greenhouse maintained at 75 day/65 nite (24 d/18 n. Upon germination, seedlings are hand-watered approx. every other day. | ||
| Establishment Phase: | Germination occurs within 10 days and is fairly uniform. First true leaves appear ~2 weeks after germination. Shoot and root development is slow. Prefers moderately dry soil conditions. Seedling are fertilized once a week with 9-45-15 liquid NPK. | ||
| Active Growth Phase: | Plants are fertilized with 20-10-20 liquid NPK. | ||
| Length of Active Growth Phase: | Time to transplant: 16 weeks | ||
| Hardening Phase: | After 12 weeks of growth the seedlings are transferred in the spring to an unheated hoophouse. In late-May plugs are transplanted into the field and irrigated frequently throughout the first growing season. | ||
| Length of Hardening Phase: | 45 days | ||
| Harvesting, Storage and Shipping: | Plant produce seed in their second growing season. Seed is harvested in mid-August in southcentral Montana at 3200 ft. | ||
| Length of Storage: | 6- year-old seed at least 50% viable | ||
| Other Comments: | This species is a native perennial growing from a stout rootstock. It tolerates drought and poor soils well. The stout rootstock provides excellent soil stabilization. This species can be direct field planted in early spring or late fall with good success. It was container-grown in this case to optimize production due to the small quantity of seed collected. | ||
