This species is loaded with interesting alkaloids, and was actually found to have the richest overall alkaloid content in the investigation of Phalaris species conducted by Festi and Samorini. Originally from Portugal, this plant's growth habits and cultural requirements are similar to Phalaris aquatica. It grows most actively during spring and fall, resting during the heat of midsummer and the short cool days of winter. Must be protected from heavy freezes. Makes a good container specimen which can be brought indoors during winter months in cold climates.
