Weeping Bottlebrush

Callistemon viminalis

This popular evergreen tree has a dense, multi-trunked, low-branching, pendulous growth habit and a moderate growth rate. Mature specimens can reach 25 to 30-feet tall in 30 years, but most trees are seen 15 to 20-feet high and wide. The narrow, light green, 3 to 4-inch-long leaves tend to grow only at the ends of the long, hanging branches, creating a weeping effect. The cylindrical, bright scarlet blooms, three to five inches long and 1-inch wide, are composed of multiple, long, bristle like stamens. These blooms appear in great abundance March through July, less so throughout the year. The flowers are followed by persistent woody capsules that are not noticed unless you are close to the tree.
