Bottlebrush, scientifically known as Callistemon citrinus, is a versatile evergreen shrub renowned for its striking crimson red flowers that bloom from summer through early fall. These shrubs can reach heights of 10-15 feet, making them excellent for use as screening plants. When pruned, Bottlebrush can be shaped into single or multi-trunk trees with small canopies, perfect for creating stunning statement pieces or patio trees in your landscape. Once established, Bottlebrush is highly drought and heat-tolerant, requiring minimal maintenance beyond occasional pruning to maintain the desired shape. Although cold hardy to zone 8b (20°F), severe or late-season frosts may damage the top growth, which can be pruned in spring, followed by fertilization to encourage new lush growth. Additionally, Bottlebrush is a fantastic addition to pollinator gardens, attracting a diverse array of insects, butterflies, and even hummingbirds.
