The Strawberry Tree (sometimes known as the Irish or Killarney Strawberry Tree) - Arbutus unedo is a gorgeous, evergreen tree from the Ericaceae family. Despite its Ericaceae background, the strawberry tree is surprisingly lime tolerant.
There are a number of cultivars available notably 'Elfin King', 'Integerrima', 'Quercifolia' and 'Rubra'.
Be aware that the young plants can be particularly tender and will require winter protection of bracken or straw. Once they have established they will be able to withstand greater cold and exposure.
You should not prune your strawberry tree as this can quickly ruin its ornamental habit, although straggly shoots may be cut back to the main stems in April.
