Rhaphiolepis indica is commonly known as the Indian hawthorn. It is a slow-growing evergreen shrub from the Rosaceae (rose) family.
It blooms with attractive colorful white and/or pink flowers in the spring. These are fragrant and showy.
It is perhaps the most popularly grown member of the Rhaphiolepus genus, and belongs to the Maleae (or apple) tribe of the family.
The shrub is a native of temperate and sub-tropical climates, with its origins traced to Southern China and South-east Asia.
It is a useful landscaping plant and is often grown as a ball shaped hedge. Plants are also often used by Bonsai enthusiasts.
In addition to its garden use, the plant is beloved by many home chefs as the fruits of some varieties may be used to make jam / jelly.
Fruits are extremely tart when raw, but are not considered poisonous for dogs, cats, and other animals.
Features of the Rhaphiolepis Indica
The shrub is a low-growing plant that can grow 4 to 6 feet tall and wide (1.2 to 1.8 m).
Rhaphiolepis indica produces beautiful star-shaped flowers, about 0.5 inches (1 cm) wide, in shades of white and pale pink.
When the flowers expire, the shrub bears dark blue berries that are loved by wildlife and have culinary use.
The leaves are broad, oblong with a thick and leathery texture, and the edges are serrated. They grow as long as 2 to 4 inches (5 to 10 cm).
New leaves are occasionally bronze-colored, becoming a deep green on maturity. The whole shrub is generally round in shape.
Where to grow the Indian Hawthorn shrub
The US Department of Agriculture advises cultivation in plant hardiness zones 8 to 10. The plant rarely thrives in temperatures below 0 degrees Fahrenheit (– 18°C).
Usually, the shrub is colorful from late fall to mid-winter (berries) and in spring (blooms).
It is a year-round shrub that can be planted individually or in a group planting.
Rhaphiolepis indica is excellent for seaside landscapes, around the house foundation, or planted close together to form an informal dense hedge.
Why is the Indian hawthorn perfect for gardeners? It is a neat shrub that does not require a lot of maintenance.
As a year-round plant, it can tolerate pollution, salty environments, drought, heat, and high humidity.
This radiant plant also brings much-needed garden color during winter.
Gardener's HQ Guide to Growing Indian hawthorn
This shrub thrives best when grown in full sun, though they also perform well in partial shade.
It does not require a unique soil pH, but compost use is best in locations where soils are dense and porous.
It will thrive where there is good drainage, and it is important to avoid disturbing the roots.
The plant requires a light general-purpose fertilizer feeding in the spring and fall.
As the plant is naturally round, no consistent pruning is required, though it is necessary for desired shapes if carrying out topiary.
If needed, pruning may be done after flowering so as to not interfere with the next bloom.
Occasionally, deadheading may help to make the shrub more appealing.
The plant is relatively pest-resistant, but proper care is vital to ensure no pests and diseases such as leafspot.

Growing Conditions and Location
Best Light Conditions: Full sunlight for best results, or areas with afternoon shade (may become scraggly).
Suitable Soil Types: Tolerant of salty soils. Can grow in most soils but moderately fertile ones should give good results.
Soil Moisture: Moist with good drainage, can tolerate dry soils once established.
Sowing, planting, and Propagation: Take cuttings from well wartered plants in autumn, once plants have stopped growing for the season.
Seeds are usually dispersed by birds. Be aware that cultivars may not stay true if grow from seed.
Sow seeds freshly harvested from the berries in late winter. Sow into flats containing a soilless potting mix. Once sown, cover with a thin layer of sand (0.6 cm, 1/4 inch). Sit the flat in water and locate indoors in an area with light shade at about 21°C (70°F).
Once hawthorn seedlings emerge and sprouted a few leaves they should be repotted into 5 cm (2 inch) pots containing a potting soil mix. As before, provide a top layer of thin sand to help protect from crown rot. Provide an initial watering with a weak fertilizer mix.
Once growing strongly, the seedlings can be transferred (in their pots) outdoors in spring (after the frost). Once they have become weather hardened they can be transplanted to their final location in the summer.
Care: Low maintenance plant. Regular watering for juvenile plants. Fertilize in spring. Light pruning to maintain appearance.
Susceptible to Leaf spot (cut off any infected parts to prevent spread, or use a bactericide).
Fireblight is also fairly common, so don't grow if you are planning to grow fruit tress such as apple or pear nearby.
Wash off aphids with soapy water.
Growing in pots and containers: Not ideal but possible. Use a large round pot filled with a potting mix. Use a bark or straw mulch.
Keep soil moist and use a regular fertilizer. Prune plants in autumn to help maintain shape and to enhance flowering the following spring.
Cultivars and Varieties:
Rhaphiolepis × delacourii 'Coates' Crimson': Slow growing, reaches about 1.5 m (5 feet) in height with a similar spread. Red leaves as a juvenile turning crimson red. Rose colored star shaped flowers bloom in mid spring through early summer. Following flowering, black berries are produced.
Rhaphiolepis indica 'Pink Lady': Faster growing than most Indian Hawthorn varieties. Reaches from 1.2 to 1.8 m (four six feet) in height and width. Tolerates light shade. Produces fragrant flowers that are a deep and dark pink.
Miscellaneous: Considered a weed in many parts of Australia, though may have become naturalized.
Can be distinguished from Rhaphiolepis umbellate (Japanese hawthorn) by its pale pink tinged color at the base of its petals and through having deeper toothed leaves.
This plant can help to attract birds to the garden (seeds are naturally spread by fruit-eating birds).
Fairly drought and salt tolerant.
Family: Rosaceae (Roses, Apple, Strawberry)
Closely Related Species: Rhaphiolepis umbellate.
