| Family Scientific Name: | Asteraceae | ||
|---|---|---|---|
| Family Common Name: | Aster family | ||
| Scientific Name: | Echinacea tennesseensis | ||
| Common Name: | Tennessee Purple Coneflower | ||
| Ecotype: | endangered species | ||
| Propagation Goal: | plants | ||
| Propagation Method: | seed | ||
| ProductType: | Plug + (container-field grown hybrids) | ||
| Time To Grow: | 0 | ||
| Target Specifications: | 10 weeks to seedlings ready for to transplant to the field. | ||
| Propagule Collection: | Anytime after seed head peduncles are brown and dried. | ||
| Propagule Processing: | Hammermill or heavy duty brush thresher followed by a seed blower to remove most debris followed by hand picking. | ||
| Pre-Planting Treatments: | Seeds are soaked for 24 hours in a 1mmol solution of ethephon (30 ml was adequate per 100 seeds in germination boxes with no blotters). The ethephon solution is then discarded and the seeds are transferred to germ boxes with blotters moistened with distilled water. The boxes are placed in cold storage (38F) for four weeks. Boxes are then transferred to germinators at a constant 25C. Radicles emerged in as little as 2 days and transplanting to celled flats is started in 1 week. 3.3 liters distilled water + 0.4786 grams ethephon = 1mmol Ethephon. Another procedure that works well is GA3 at 1mM concentration. (i.e. 0.346g/l) | ||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
After about a month of growing in celled flats, seedlings with two or three fully elongated true leaves are moved to field sites (tilled ground). Seedlings are watered and mulched. | ||
| Establishment Phase: |
Seedlings establish quickly with some plants flowering the first year but most do not until the following year. Water occasionally during the first weeks after transplanting to the field. |
||
| Length of Establishment Phase: | one summer | ||
| Other Comments: | this protocol works for all species of Echinacea | ||
