Veronicastrum virginicum - Culver's Root - seed started February 2015 - picture taken April 13, 2016
Height - 5 ft Flower Color - White Blooms - June through August Sun - Full sun, part sun Soil - Moist, loamy
Zone - 3 to 8 Family –Scrophulariaceae (Snapdragon)
Propagation Notes - Cold/Moist stratification for 60 days. House temperature 65°F - Excellent seed germination rate Growth Rate - Very slow - Culver's root was started in February 2015 at the same time as other seedlings. Although I have hundreds of sprouts they are considerably smaller then I would have expected. Either Veronicastrum virginicum is a slow growing native plant or the cool temperature of our house slowed plant development.
