Fast-growing, Callistemon viminalis (Weeping Bottlebrush) is a beautiful evergreen shrub or small tree adorned with pendulous branches clothed with narrow, light green leaves. The plant is covered with dense spikes, up to 6 in. long (15 cm), of bright blood-red flowers that resemble bottlebrushes in late spring and early summer then sporadically. The blooms are a copious source of nectar for birds and hummingbirds. New growth emerges from the ends of the inflorescence and the young leaves are covered with bronze hairs. The flowers give way to woody fruit capsules which release their seeds annually. Weeping Bottlebrush is useful as a screen plant, in erosion control or as a specimen or street tree.
