Amsonia hubrichtii
BLUESTAR
SKU: 1290-5
Extremely beautiful sky-blue star-shaped flowers! A durable insect and disease resistant perennial. Is dealing better with dryer sites than other Amsonia. This plant was awarded the North American perennial of the year in 2011. The foliage turns a beautiful yellow and bronze in autumn!
Height: 90cm
Hardiness zones: 4-9
Location: Sun or part shade
Seeds per packet: 5
Note: Ornamental use only. These seeds and/or plants may be poisonous.
Germination: Sow the seeds just under the surface and water in. Leave them at room temperature for 4 weeks. This helps break the phytohormones which inhibit germination. They will not grow yet. Then a cooling period is required. Cover them with plastic and place in a fridge for 6 weeks. Be sure they stay moist. After the cold-moist stratification period they are then brought back to a cool room (15-18C, 59-68F) for them to germinate. Germination can be erratic, generally 30-90 days after the warming period, though some can take longer.
