This young lemon bottlebrush will slowly grow to an ultimate height of about 12 feet.


Lemon bottlebrush is a small tree or large shrub that gets 6-12 ft (2-4 m) tall and 6-9 ft (2-3 m) wide. The leaves are narrow, lance shaped, and leathery, with a distinctly citrus aroma (thus the common name). The bright red fuzzy looking flowers are composed mostly of stamens. These are arranged radially around the stem tips in plump clusters like the bristles on one of those brushes used to clean the inside of bottles. Lemon bottlebrush blooms in early spring when it covers itself in the bright red blossoms and a few flower clusters are also produced sporadically throughout the summer. The bark is somewhat rough and light brown. Other less hardy forms of bottlebrush are available, including C. viminalis (weeping bottlebrush) and C. speciosus (showy bottlebrush). Callistemon rigidus is about equally hardy to cold with smaller flowers.
