| Family Scientific Name: | Scrophulariaceae | ||
|---|---|---|---|
| Family Common Name: | Figwort | ||
| Scientific Name: | Keckiella lemmonii | ||
| Common Name: | Bush penstemon | ||
| Species Code: | KELE | ||
| Ecotype: | Rogue River-Siskiyou National Forest, Oregon | ||
| General Distribution: | It is native to Oregon and northern California, where it grows in the coniferous forests and chaparral of coastal and inland mountain ranges. Its range may extend just into Nevada in the High Sierra | ||
| Propagation Goal: | Plants | ||
| Propagation Method: | Seed | ||
| ProductType: | Container (plug) | ||
| Stock Type: | 262 ml (16 in3) container | ||
| Time To Grow: | 18 weeks | ||
| Target Specifications: | Stock Type: Container seedling Root System: Firm plug in container. | ||
| Pre-Planting Treatments: | Seeds are placed in a solution of 250 mg/L GA3, soaked for 24 hours, rinsed, and soaked for an additional 4 hours in water. Seeds are sown into trays filled with stabilized medium plugs (Q-plugs). Trays are sealed inside plastic bags and placed into refrigeration at 1 to 3 °C for 60 days. Trays are checked weekly and kept moist throughout the stratification period. If mold is evident, trays should be treated with 1% hydrogen peroxide. | ||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Greenhouse growing facility. Q-plugs are lightly covered with nursery grit. Seedlings are transplanted to target containers approximately 3 weeks following removal from stratification. Growing medium used is 40:20:20:20 peat:composted fir bark:perlite:pumice with Nutricote controlled release fertilizer (18N:6P2O5:8K2O with minors; 180-d release rate at 21C) at the rate of 1.5 gram Nutricote per 262 ml container. |
||
| Establishment Phase: | Germination is not very uniform, depending on the quality of the seeds, and can take up to 3 weeks to be complete. Following germination (while still in Q-plugs), plants are fertilized with soluble 12-2-14-6Ca-3Mg at 75 to 100 ppm for 2 weeks. | ||
| Length of Establishment Phase: | 3 weeks | ||
| Active Growth Phase: | During the growing season, fertilization depends on weather and physiological needs. Soluble 20-9-20 NPK, 20-18-18 NPK, or 17-5-24 NPK at 100 to 150 ppm is applied weekly throughout the growing season. | ||
| Length of Active Growth Phase: | 10 to 12 weeks | ||
| Hardening Phase: | No dry-down is done to induce dormancy. Seedlings are moved to an outdoor growing area in mid-September. | ||
| Length of Hardening Phase: | 3 weeks | ||
| Harvesting, Storage and Shipping: |
Harvest Date: Mid-October Storage Conditions: Seedlings are usually outplanted in fall. No storage except in outdoor growing area. Plants are well irrigated prior to shipping and shipped in containers. |
