Description

Indian hawthorns are among the most popular and widely planted flowering shrubs throughout the Inland Empire. They are easy to grow, reliable and long-lived. These qualities are greatly appreciated in both residential and commercial gardens and landscapes.

Many cultivars of Indian hawthorn have become available from nurseries over the years; some are large and robust while others are petite. They are characterized by dark green leaves and heavy springtime flowering performance. Depending upon the cultivar, flowers range in color from white to light pink; some plants produce small purple-black berries.

Indian hawthorns are used in many ways including slopes and banks, borders, containers, patio trees and a clipped hedges. They grow best in sunny locations with regular moisture throughout the year, and are adapted to many soil conditions. Some popular cultivars include: R. i. 'Ballerina' is a compact cultivar that grows 2-3 ft. high and has deep pink flowers; R. i. 'Clara' mounds 3-5 ft. high and 5-6 ft. wide and produces white flowers; R. i. 'Springtime' is a robust shrub 5-8 ft. high and as wide and has clear pink flowers.

Water Needs

All species and cultivars of Indian hawthorn grow well in sunny locations with normal winter rainfall and periodic summer water. The chart below provides a baseline irrigation schedule for this species. It should be noted there are several winter months marked by an asterisk (*) when rains can provide sufficient moisture and irrigation is not needed. The high and low range of moisture indicates it can grow with varying amounts of water; higher amounts of water within this range will result in stronger springtime flowering performance and summer foliage character.
