    Plants are grown from root cuttings at the nursery. Original source came from seeds collected off a population growing on the edge of bottomland forest in Pender County, North Carolina.

    Comments

    Our plants are from one of the most southern populations of Purple Milkweed and should be more adaptable to southern regions than plants from northern sources.

    Propagation

    Viable seed sown and exposed over the winter to a moist, cool period should germinate in the spring. Pencil thick pieces of root dug up in late winter and potted will slowly form roots and develop into a new plant.
