About

Arbutus unedo, commonly known as strawberry-tree, or strawberry tree, also called madroño in Spanish, is an evergreen shrub or small tree in the family Ericaceae, native to the Mediterranean Basin and Western Europe. The tree is well known for its fruit, the arbutus berry, which bears some resemblance to the strawberry, hence the common name strawberry-tree. However, it is not closely related to true strawberries of the genus Fragaria.

Its presence in Ireland also lends it the name Irish strawberry-tree, or cain, or cane apple, from the Irish name for the tree, caithne, or sometimes Killarney strawberry-tree. The strawberry-tree is the national tree of Italy because of its green leaves, its white flowers and its red berries, colours that recall the Italian flag. The flower is the national flower of Italy.

How to grow it

Arbutus unedo is quite an easy plant to cultivate, and is adaptable to many climates. Once established it is fairly drought resistant, frost resistant, shade tolerant and salt tolerant.

Lower production of fruit mass has however been reported in case of summer droughts, and frosts in flowering time were seen to decrease the amount of fruit.

Where it grows

Arbutus unedo is widespread in the Mediterranean region, in Portugal, Spain, western and southeastern France; southward in Algeria, Morocco, Libya, and Tunisia, and eastward in Albania, Bulgaria, Croatia, Greece, Italy, Malta, Montenegro, Slovenia, Turkey, Israel, Palestine, Jordan, Lebanon, and Syria. It is naturalised in Great Britain and Ireland, being particularly common in western Ireland, where it is an archaeophyte that was formerly believed to be native.
