| Family Scientific Name: | Asteraceae | ||
|---|---|---|---|
| Scientific Name: | Symphyotrichum cordifolium (L.) Nesom | ||
| Common Synonym: | Aster cordifolius L. | ||
| Common Name: | Heartleaf aster, Common blue wood aster | ||
| Species Code: | SYCO4 | ||
| Ecotype: | Natchez Trace Parkway, Mississippi. | ||
| General Distribution: | Found from Nova Scotia to Minnesota, south to Georgia and Missouri. | ||
| Propagation Goal: | plants | ||
| Propagation Method: | seed | ||
| ProductType: | Propagules (seeds, cuttings, poles, etc.) | ||
| Time To Grow: | 0 | ||
| Propagule Collection: | Natchez Trace Parkway, from around Jackson, Mississippi to the terminus in Natchez, Mississippi by B .B. Billingsley, Jr. in 1990. | ||
| Propagule Processing: |
Seed Processing: Seeds were harvested using a vacuum. Pappus attached to the seedsmade direct cleaning with an air screen cleanerdifficult. In 1993 seeds were conditioned before cleaning using a brush machine to remove the pappus, which improved purity. However, the process was very time consuming and was not repeated in subsequent years. Seeds/Kg: 4,400,000. Germination:In 1993=61%, in 1994=44%. Purity: In 1993=76%, in 1994=22%. |
||
| Pre-Planting Treatments: | Seed Treatments: None required, however, seeds of several aster species germinate more rapidly if stratified (Phillips, 1985; Andersen, 1968). | ||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Propagation Environment: Greenhouse and field grown. Container Type and Volume: Seedlings were grown in the greenhouse for planting in the field only. Containers used were cell packs with a 3.8 cmX 6 cm (1.5" X 2.4") cell size. Growing Media: Jiffy Mix Plus. |
||
| Establishment Phase: |
Sowing Date: September to October. Emergence and Date: Most seeds germinate in the spring. Sowing/Planting Technique: Mixed seed with sand and surface applied to plowed areas that had been cultipacked or to areas that had been closely mowed. Rates of 2.24 to 3.36 kilogram PLS per hectare (2 to 3 pounds per acre) would be required to plant a production field. Establishment Phase: Establishment was fairly poor from direct seeding, so greenhouse grown transplants were used for later plantings. |
||
| Harvesting, Storage and Shipping: |
Harvest Date: Late September to October. Seed Storage: Normal cool, dry storage. PMC cooler is maintained at 12.7 C (55 F) and 45% relative humidity. Seed Dormancy: No prolonged dormancy is apparent. |
||
| Length of Storage: | <b>Storage Duration:</b> Unknown. | ||
| Other Comments: | Plants overwinter as a rosette. Normally heartleaf aster is found growing in wooded areas, however, the production field was in a more open site. The plants grew vigorously in the open and required staking. | ||
