Vernonia Noveboracensis. Native to the stream banks and moist thickets of the Eastern United States, Vernonia Noveboracensis is an upright perennial that produces clusters of purple flowers from August to September. It is a great plant for the back of the cottage garden or planting in meadows or naturalized areas.
Plant in moist soil in full sun. The "iron-like" qualities of this plant help it tolerate deer, clay soil, and wet soil. It will grow 4-6' tall and 3-4' wide.
Seeds require a cold treatment. Sow directly outside in the late fall and cover with 1/4" soil and the seeds will germinate in the spring. The seeds may also be mixed with moist, not wet, germination mix, put in a plastic bag and refrigerated for 6-8 weeks. After refrigeration, sow the seeds into a tray of moist germination mix. When seedlings are large enought , they can be hardened off and transplanted into the garden.
USDA Zone 5-9.
Heirloom seeds are collected, cleaned and packaged by hand at Mount Vernon.
