Montpelier Rockrose will not survive winters below 10° or imperfect
drainage. But, where it does survive, it lives with a flourish. This photo
shows a sprawling Montpelier Rockrose that has covered more than 20
feet just by laying its stems in the earth and rooting
wonderful beneficial insect plants. The pollen filled centers are especially
loved by bees. Rockroses flower for about six weeks in spring. As the day
ends the open flower floats to the ground. The next morning a new one will
unfold to take its place.
While extremely drought tolerant, Rockroses benefit from water in the
summer in a dry climate. This encourages the most flowers and expansion of
Rockroses never need pruning but can be pruned at anytime after
flowering for shape. They should not be cut way back. Old wood may not
produce new growth.
