Southern water-plantain
Alisma subcordatum
Southern water-plantain is an aquatic or semi-aquatic perennial best suited to pond edges, rain gardens, or consistently wet, boggy soils. It produces delicate white flowers on tall scapes that attract pollinators throughout summer. Plant in full sun to part shade and never allow the soil to dry out; it performs best with its roots sitting in shallow water.
