Propagation of Redhead Grass (Potamogeton perfoliatus L.) Transplants for Restoration Projects

Abstract

Redhead grass (Potamogeton perfoliatus L. [Potamogetonaceae]) is a perennial submerged aquatic plant targeted for restoration plantings in Chesapeake Bay. We have not been successful using seed to generate transplant material for restoration projects, but stem cuttings are easily started in the greenhouse. Cuttings root in a 1:1 soil:sand mix in about 2 wk, and transplants from stem cuttings can be field planted about 12 wk after rooting. Our simple protocol for rooting and growing cuttings can be used for mass production of plants.
