It would be best if you protect them from winds and, ideally, plant them in a location where they can receive four hours of sunshine every day. Water it regularly and remove any wilted flowers to promote further blooming. These cold-hardy plants were created by crossing two highly hardy American species, R. prinophyllum and R. canadense.
