A callistemon said to be hardier than many other cultivars, 'Amarette' offers year-round interest in sheltered or southerly parts of the UK with its slender, aromatic foliage. This evergreen shrub is mainly sought after for its bottlebrush-like flowerheads, which appear over a long period in spring and summer. A compact plant, it could be grown at the base of a sunny sheltered wall in milder regions, or kept in a larger pot and moved to a sheltered position during the colder months.
