| Scientific Name: | Penstemon virgatus | ||
| Common Name: | Penstemon | ||
| Ecotype: | Colorado, Moraine Park (98-044s, 98-122s), Hollowell Park (98-085s) | ||
| Propagation Goal: | seeds | ||
| Propagation Method: | seed | ||
| ProductType: | Propagules (seeds, cuttings, poles, etc.) | ||
| Time To Grow: | 0 | ||
| Propagule Collection: |
Seed cleaning technique: Seeds removed from seed heads by crushing seeds head or using tweezers. Use of screens helpful for separating seed from miscellaneous plant material. Moraine Park (98-044s, 98-122s) collected on 10/10/98; Hollowell Park (98-085s) collected on 9/12/98. |
||
| Pre-Planting Treatments: | Seed treatments: None, 30 day cold moist treatment. | ||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Propagation Environment: Greenhouse, 65-70§F day/55§F night. Propagated on orange heat pad (set to 70§F) under tent with misters set 8 am-8 pm, with 10 sec/15 min watering intervals. One week after germination, seedlings were moved to mister area without tent. Germination media: Fafard Germinating Mix (superfine). Growing media: Fafard Growing Mix 2. |
||
| Establishment Phase: |
Sowing/planting technique: Sown in 36 pk, 3-5 seeds/slot. Time to germination: 12-15 days. Establishment Phase: Germination slow and uneven. Time to potting: 1 to 1-1/2 months. Moraine Park (98-044s, 98-122s) sowed 12/4/98; Hollowell Park (98-085s) sowed on 11/16/98. |
||
| Harvesting, Storage and Shipping: | Seed storage condition: Seed stored in the greenhouse. | ||
| Other Comments: | Comments: 98-044s was cold, moist treated for one month prior to planting while 98-122s was stored in the refrigerator. Hollowell was stored in greenhouse so cold treatment may or may not be necessary. | ||
