About plant names...

Tall shrubs or small trees, red bottlebrushes have bright red flowers that really do look exactly like bottlebrushes. Most of the 34 species of Callistemon originate from Australia; a few are from New Caledonia. In the extreme southern and western United States they are popular ornamental plants, but they have not become naturalized in North America.

Identification: The red filaments in bottlebrush “flowers” are really the flowers, they are the stamens. The flowers themselves are in the core, small and white. The key identifying characteristic of these plants is the cylindrical shape of the brushes. Plants are 6-15' (1.8-4.6 m) high. The seeds are unusual, and remain on the trees for long periods.
