The Bottlebrush shrub is named for its cylindrical, brush-like, abundant red flowers. It grows fast and is drought-resistant, and requires very little maintenance once established. The Bottlebrush can bring vibrant color to your garden area all year, beginning in early spring and lasting until cold weather. It attracts butterflies, insects, hummingbirds, and other nectar-feeding birds. The tree loves a warm climate, moist soil, and a lot of sunlight. It reaches a mature height of 10 feet.
