- Description
-
Southern Swamp Lily is a perennial bulb in the Amaryllis family. It is native to wetlands, swamps, marshes, and stream banks from South Carolina to Florida and west to Texas. The species grows in small groups in still-water habitats and prefers a water depth of 1-6 inches but will grow up to a 12-inch depth.
Although it is native to wet sites it will grow in moist garden environments or it can be planted in containers that are kept moist to wet. Only use a pot 2 inches larger than the bulb. If growing in the garden, mulch heavily in the winter. Otherwise, it can be grown in water gardens, along streams, ponds or bogs. It prefers full sun to partial shade. Do not disturb the bulbs once planted or it may take up to 2-3 years before it blooms again.

- Wildlife Value:
- Submerged portions provide habitats for many micro and macroinvertebrates. These invertebrates, in turn, are used as food by fish and other wildlife species (e.g. amphibians, reptiles, ducks, etc.). After aquatic plants die, their decomposition by bacteria and fungi provides food (called “detritus”) for many aquatic invertebrates. Attracts moths at night with increased fragrance.
