Erect bottlebrush is a small tree or shrub typically reaching 15 - 20 feet in height, but potentially much taller. It has a spreading, upright, oval or rounded, moderately dense crown; the trunk has red brown fibrous bark. Leaves are evergreen, stiff, alternate, gray-green in color, linear, 2 - 4 inches long and aromatic. Flowers are red with showy stamens encircling branch stems and form a 4 inch long cylinder which looks like a bottlebrush. Bees, butterflies and hummingbirds are attracted to the flowers. Fruits develop as tight clusters on the stem and are persistent, round hard seed capsules resembling small acorn caps and are about 1/4 - 1/2 inch in diameter. Seeds or cuttings are used for propagation. This bottlebrush tolerates highly alkaline to slightly acidic soils and is quite hardy once established. With its attractive foliage and unusual showy flowers, erect bottlebrush has a variety of landscape uses, including as a reclamation plant, trained as a standard hedge near a deck or patio, a border planting along a fence or driveway, or pruned up as a single-trunked specimen tree. It is not considered an invasive species.
