Rock rose plants, Cistus, are flowering evergreen shrubs native to the Mediterranean. The plant's large, colorful blooms only last for one day, opening at dawn and falling from the plant by evening. Rock rose plants are easy to grow, thrive with minimal care and tolerate even the poorest soil.
Only a few species of rock rose plants grow in North America. They grow in hardiness zones 8 to 11 and bloom from mid-spring through early summer. These plants thrive best when planted in full sun. Rock rose plants need regular watering initially, but once established, they need little care. While the plants tolerate poor soil, good drainage is essential to avoid root rot.
