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.
