Water Hyacinth Care
A frost-tender aquatic perennial, water hyacinth is grown as an annual in Zones 8 and below. It is easy to grow in still water and full sun. Plant it in spring by scattering small bunches of plants on the water surface after the last frost date. Be mindful because they spread quickly in warm water via stems from the main plant, producing numerous new plants. Remove excess plants as needed. Overwinter these frost-tender plants by removing them from the water garden and planting them in containers of moist loam in late fall. Place the container in a bright sunny spot where temperatures stay between 60 and 70-degrees. Many gardeners prefer to grow water hyacinth as an annual by purchasing new plants each spring. Brighten your summer with these beautiful summer flowers and bulbs.
