Keep well-watered during dry periods in the Summer. Will not tolerate wet soils. To help improve conditions, mix in peat moss, compost, or dehydrated manure. May be mulched around the base during the first Winter. Good for naturalizing. Clusters of drooping heart-shaped blooms. Definitely an old fashioned plant - was probably in grandmother's garden.
