Crimson Bottlebrush Seeds

Landscape Rating: ⭐⭐⭐⭐⭐ (5/5 Stars)

Plant Characteristics

Crimson Bottlebrush is one of the most colorful and easily recognized flowering shrubs or small trees in the landscape. Native to Australia, this evergreen ornamental is famous for its brilliant crimson flower spikes that closely resemble old-fashioned bottle brushes.

Mature plants typically reach 10 to 20 feet in height with a rounded, graceful form. The narrow, aromatic leaves release a pleasant citrus fragrance when crushed, giving rise to the species name citrinus.

Throughout spring and often again during summer and fall, the branches become covered with striking red flower spikes composed of hundreds of bright stamens. These vivid blooms create a dramatic display against the rich green foliage.

As a specimen lawn plant, Crimson Bottlebrush provides year-round beauty, colorful blooms, and excellent wildlife value.
