Large Flower False Rosemary (Conradina grandiflora) is an evergreen shrub that may grow as high as 4 feet. It produces showy, purple-lavender flowers that are aromatic and blooms spring and fall. It requires full sun and well-drained, sandy soil. This is a state endangered plant that should be purchased from reputable nurseries that specialize in Florida-native plants. Use it in a wildflower garden or as a border plant and it will attract bees and other pollinators.
