This species is easily grown from seed. If seeds are to be stored they should be collected when the follicles turn brown and split. Allow the pods to dry then remove seeds. Before planting the hard coated seed should be scarified and soaked in water for 1-2 days. Seeds collected when still green can be sown fresh and will germinate with no treatment. The fruit ripens from August to October. Store dry seeds at about 40 degrees F. Plant 1/4 inch deep in spring or fall. Tip cuttings taken in May, or woody cuttings taken any time, are also an effective method of mass producing Amsonia. Plants may be increased by root division while the plants are dormant.
Amsonia prefers rich soil, high organic matter, and moist locations.
Moist or wet woods or prairie.
