Description: numerous small purple-violet flowers grow on a branching stalk at the top of the plant.
These perennial,
open, branching plants are up to 4 feet tall, with dense leaves covered by bristly hairs.
Suggested seed treatment: You should provide 30 to 45 days of cold moist stratification. Many prairie wildflower seeds benefit by moist cold stratification, some require it to germinate. Seed that you purchase from Oak Prairie Farm has not received cold moist stratification. Direct planting tips: Plant seed in desired location 1/4 inch deep in the soil, and firm. Transplants: If you grow transplants from our seed: transplant while dormant in spring or fall, trim long roots, plant with buds just below the soil surface, space 2 to 3 feet apart. Very vigorous. Companion prairie plants: Spiderwort, Butterfly Milkweed, Black-eyed Susan, Big bluestem, Indian grass. Comments: Very vigorous. Attractive as cut flowers in the fall. |
