Adding a tropical look to the landscape, Callistemon (Bottlebrushes) are evergreen shrubs with aromatic, linear to lance-shaped leaves and spectacular flowers that resemble bottlebrushes. Irresistible to nectar-feeding birds and insects, they bloom intermittently throughout the year in frost free areas. Bottlebrushes make excellent garden plants. Some are dense and compact, making an excellent unclipped hedge, others can be pruned into small trees. All are great accent plants and most can be grown in containers. Callistemons love moisture and grow well in a wide variety of soils, except those which are highly alkaline. Plants grown in full sun produce the best flowers.
