| Family Scientific Name: | Asteraceae | ||
|---|---|---|---|
| Family Common Name: | aster | ||
| Scientific Name: | Aster suspicata | ||
| Common Synonym: | Aster douglasii | ||
| Common Name: | Douglas aster | ||
| Species Code: | SYSUS | ||
| Ecotype: | northern Oregon coast | ||
| General Distribution: | Coastal areas, moist riverbeds, west-side forest areas of Northwestern US and Canada | ||
| Propagation Goal: | plants | ||
| Propagation Method: | seed | ||
| ProductType: | Container (plug) | ||
| Time To Grow: | Weeks | ||
| Propagule Collection: | Moderate; Seeds ripen over a period of weeks to months, depending on fall weather. Seeds fly away when ripe. Plants are usually easy to identify and moderately easy to find. Seeds per pound: 800,000–1,300,000 | ||
| Propagule Processing: | Fluff and seeds harvested with the leaf blower or seed stripper are placed on tarps to dry, turning often to prevent molding. Run material through a brush machine to break the pappas from the seed, then through a large air screen machine (Crippen) with a lot of rubber balls to sift the seeds from the fuzz. A small air screen machine is then used for fine cleaning. | ||
| Pre-Planting Treatments: | None | ||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Seed production fields are equally successful from direct seeding or plugs transplanted in the fall or spring. Seeds do not exhibit dormancy and require no pretreatment prior to sowing. If direct seeded, the target rate should be approximately 50 seeds per square foot, or 1.7–2.7 pounds per acre, at a depth of no more than ¼ inch in rows that are 24-36 inches apart. Plugs can be transplanted into 24-inch rows at 12-inch spacing (depending on equipment). | ||
