Sow the seeds in moist potting soil, cover them with a thin layer of soil, and water gently. Maintain a consistent moisture level and temperature of about 70-75°F. Germination should occur within two to three weeks. Thin the seedlings to one per pot after they develop the second set of true leaves. Transplant the seedlings outdoors in the spring after the threat of frost has passed.
Division
Lythrum flagellare can also be propagated through division. Divide established plants in the spring before new growth appears or in the fall after the growing season. Dig up the plant and gently pull apart the root clumps into sections with a sharp knife or spade. Each division should contain a piece of the rhizome with at least one healthy shoot. Replant the divisions at the same depth as before, and water thoroughly.
Cuttings
Another way to propagate Lythrum flagellare is through stem cuttings. Take stem cuttings from healthy, mature plants in the summer. Cut a 4-6 inch stem section with two to three leaf nodes. Strip off any leaves on the lower half of the stem, and dip the cut end in rooting hormone. Insert the cutting about an inch deep into moist potting soil in a container. Put a clear plastic bag over the pot to maintain humidity, and place the container in bright, indirect light. Keep the soil moist, and mist the leaves daily. After four to six weeks, the cuttings should root. Transplant the rooted cuttings to their final location in the fall or spring.
Propagation of Lythrum flagellare is relatively simple and requires very little preparation. By following the above methods, gardeners can easily add this beautiful plant to their collection.
