Family:Ericaceae

The Strawberry Tree is an evergreen shrub or small tree belonging to the Heath family, primarily found in the Mediterranean region and western Europe. Its vibrant red, edible fruits ripen in the autumn, boasting a high sugar content, though they tend to have a rather mild flavor. These fruits can be utilized for making jams and jellies. However, fruit yield can be inconsistent, influenced by weather conditions, and the fruits are prone to bruising, which limits its commercial cultivation primarily to brandy production in Portugal.

This plant exhibits slow growth, typically adding 12 to 24 inches annually, and generally reaches a height of around 15 feet, although it can grow as tall as 35 feet. It can be cultivated as a shrub or pruned into a tree form to highlight its unique peeling bark.

The Strawberry Tree is relatively easy to cultivate and adapts well to a variety of climates and well-drained soils, including less fertile ones. Once established, it can tolerate full sun to partial shade, as well as salt and drought conditions. Regular light pruning of the shoots helps maintain its appealing shape. It serves well as a specimen plant, for screening purposes, or as a small shade tree adjacent to patios. With its glossy foliage, white blossoms, red fruits, and exfoliating bark, this plant offers year-round visual interest for any landscape.

In terms of pests and diseases, the Strawberry Tree is vulnerable to scales and thrips. It may also face occasional issues with anthracnose, Phytophthora, root rot, and rust. The plant tends to struggle in humid environments, and fruit drop can create a mess near hardscaped areas.
