Erica terminalis is a form of “Tree Heather” and can grow up to 90 cm or more in favourable conditions. The growth is stiffly erect. Flowers are produced over a long season from summer into autumn months. They fade to a warm brown colour and look attractive through the winter. Plants will tolerate alkaline soils and flourish in a sheltered, sunny situation. Sometimes known as the Corsican Heath, native to the western mediterranean. Not too easy to buy a plant nowadays; but, I found some at Bodnant.
