| Propagation Method: | seed | ||
| ProductType: | Container (plug) | ||
| Stock Type: | 1+0 container plug | ||
| Time To Grow: | 6 Months | ||
| Target Specifications: | A well developed plant suitable for mechanical transplanting that has at least 6 inches of top growth and a dense, fibrous root system. | ||
| Propagule Collection: | Seed of Stones River National Battlefield source blue mistflower was hand harvested from existing populations within the confines of Stones River National Battlefield. | ||
| Pre-Planting Treatments: | Seed is planted into round cell greenhouse flat liners with 38 cells per flat that have been filled with coarse processed bark and composted pine bark growing medium. Seed is surface sown at a rate of 3-5 seeds per cell and lightly covered with starter sized, 1/16" - 1/8" diameter, granite poultry grit to combat damping off diseases. Prepared flats are lightly hand watered to slightly moisten the growing medium and cold stratified at 35 degrees Fahrenheit for a minimum of 21 days. | ||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Stratified seed is placed in a greenhouse maintained under natural lighting and at a minimum temperature of 70 degrees Fahrenheit. Soil moisture is maintained during germination by an automatic overhead watering system set to cycle for 20 seconds every thirty minutes during daylight hours. | ||
| Establishment Phase: | Germination typically occurs 7 - 10 days after placement in the greenhouse. | ||
| Length of Establishment Phase: | 7-10 days | ||
| Length of Active Growth Phase: | 2-4 months | ||
| Hardening Phase: | Acclimation is typically accomplished through placement of seedlings outdoors in a protected location for a 1-2 week period prior to transplanting. | ||
| Length of Hardening Phase: | 1-2 weeks | ||
