Blue water hyssop is a great low-growing bog plant for trailing over edges, cascading down a waterfall, bogs or submerged, common to lime sink ponds and the coastal plain, lakes, cypress ponds, ox box lakes, slow moving streams and rivers, and in ditches and canals. It can grow submerged in water as deep as 1.8 m. It prefers full sun and lots of water.It tolerates drought and could be planted in bioswales. It has become invasive in ponds where grass carp have been used to control submersed weeds such as Hydrilla. Blue water hyssop is very hard to control because most treatments use either a contact herbicide that requires repeat applications or an expensive systemic herbicide like fluridone at a high rate and expense.
