Description White Rockrose gains its name from the white flowers, each with a yellow center.

  Morphology:
This is an evergreen shrub which grows to 5’ in height and width. Multiple plants can be set in line to form a solid dense hedge. In late May as flowers begin to form the effect can be very striking with the plethora of white blossoms, each of which are only open for a day. They are 1.5” across. Flowers form on ends of the branches.
Leaves are arranged in an opposite fashion. They have an ovate shape and are typically 2” long, and up to an inch in width.

  Adaptation:
Select a full sun site. Once established this is a drought tolerant shrub.

  Pests:
None.
