Care essentials
Light
Water hyssop performs best in full sun to part shade in NE Florida. Full sun maximizes flowering; part shade is tolerated in humid, wet spots near ponds or rain garden edges.
Water
This native wetland creeper thrives with consistent moisture or shallow standing water. It is ideal for rain gardens, pond margins, and wet low spots in NE Florida; do not allow soil to dry out completely.
Soil & Fertilizer
Grows in sandy to loamy moist or wet soils with neutral to slightly alkaline pH. Minimal fertilizer needed — light application of a balanced granular fertilizer in spring is sufficient; excessive nitrogen promotes rank growth over flowering.
