Care essentials
Light
Performs best in full sun but tolerates part sun; in NE Florida, full-sun wet sites such as pond edges and rain garden basins are ideal. Adequate light helps maintain the upright form and prevents flopping.
Water
A wetland native that thrives in saturated soils, shallow standing water (up to 4 inches deep), or consistently moist garden soils. Perfect for pond margins, bioswales, and rain gardens in NE Florida. Will also grow in average garden soil kept consistently moist.
Soil & Fertilizer
Adapts to sandy, loamy, or clay soils as long as moisture is high. No fertilizer required in typical wetland or rain garden settings. Cut back old stems in early spring before new growth emerges; divide every few years if clumps become too large.
