Rhaphiolepis

A genus of 10 species of evergreen shrubs or trees that are closely related to the Photinia. They are often called Indian Hawthorn, a name that is misleading because they do not have thorns. They are tolerant of hard pruning and make excellent hedges.
They prefer full sun and just about any well drained soil though preferring fertile and light, acidic or alkaline. Salt tolerant and moderately drought tolerant, they are tolerant of seashore conditions and are an excellent plant for such environments.
Mulch should be applied to the root zone since they do not like root disturbance and raking, hoeing, and digging over the shallow root zone will harm growth.
Deer do like to eat the foliage during winter, due to this it must be restricted to urban or fenced in yards in areas that deer are abundant. Netting may be a temporary solution for the deer. Leaf spot may also defoliate some species and cultivars by late summer.
Propagation is from semi-ripe cuttings taken during late summer, layering and seed.

  1. Do you know of any Rhaphiolepis that are sterile and do not produce fruit?
