Eye Catching Ornamental Bottlebrush Trees
High temperatures, moist soil, and bright sunlight are the basic requirements for bottlebrush trees to grow well. They are perfect ornamental trees with eye-catching flowers. It is native to Australia but also grows in areas with temperate climates. There are several varieties of these trees, including a weeping form and dwarf sizes. Most cultivars have red, pink, or white flowers. Standard bottlebrush trees grow to an average of 15 feet (4.5 meters) tall, although some specimens can grow slightly taller. Each has a typical tree shape with an average canopy spread. Callistemon viminalis is the weeping form, closely resembling a weeping willow. This variety can grow to 20 feet (6 meters) tall, with long branches drooping toward the ground. Dwarf bottlebrushes are more of a shrub than a tree, growing to only 3 feet (1 meter) tall.
Bottlebrush trees prefers subtropical climates and can tolerate only short periods of frost. It can be killed by exposure to freezing temperatures. Aside from that, the bottlebrush tree is a fairly hardy tree that will grow in sandy or rich soils. Although it prefers regular watering, it will survive short periods of drought. Bottlebrush trees are usually grown from cuttings as most cultivated specimens are hybrids. Trees grown from hybrid seeds may not be true to the parent and may result in a tree that is susceptible to pests and diseases. Rooted cuttings should be planted in the late summer in areas that receive full sun. Mulch placed around the planting help the soil retain moisture.
