Planting & Care

Sow seeds in a moist seed-starting mix, pressing them lightly into the surface without covering, as light may aid germination. Keep the medium consistently wet and maintain a temperature around 65-75°F. Germination can be slow and irregular; patience is required. Once seedlings have several true leaves, transplant them into individual pots and grow them on in consistently moist conditions.

For direct sowing, scatter seeds onto wet soil in late fall or early spring. Choose a site that remains moist or periodically flooded, such as a rain garden, bioswale, or pond edge. Water regularly to keep soil saturated, especially during the first growing season. Established plants are low-maintenance and generally pest-free.
