ASTER ALPINE BLUE, DWARF ASTER
SKU: 510-010
Description
Aster alpinus (Alpine aster) is an ornamental plant native to the mountains of Europe (including the Alps), with a subspecies native to Canada and the United States.
It grows to be about 6–12 inches tall (15–30 cm). It may bloom in late spring or early summer or, occasionally, midsummer. In the UK this plant has gained the Royal Horticultural Society's Award of Garden Merit.
It does better in generally cooler climates. Usually it is adapted to clay, silt, loam, silty clay, sandy clay, clay loam, silt loam, sandy loam, silty clay loam and sandy clay loam soils, and prefers low fertility. The plant can tolerate a minimum temperature of -28 °C / -18. It can survive medium heat of fire. It is herbaceous and attractive to bees, butterflies, and birds.
Type: Hardy Perennial
Height: 6–12 inches tall (15–30 cm)
Location: Sun or part sun
Hardiness zones: 2-8
Seeds per pack: 10
Note: Ornamental use only. May be poisonous.
Germination: Start these seeds right away for best germination rates. Start indoors. Your planting container should have holes in the bottom for excess water to drain. These seeds require light to germinate. Sow the seeds on surface of a sterile seed-start mix, and water in. Do not bury the seeds. Leave them at room temperature (20-22 °C, 68-72 °F) for 4 weeks. If they have not germinated after 4 weeks then a cooling period is required. Cover them with plastic and place in a fridge for 4 weeks. Be sure they stay moist. After the cold-moist stratification period they are then brought back to a cool room (15C, 59F) for them to germinate. Germination can be 30-60 days after the warming period, though some will take longer.
