Taxonomic Information

Appearance

Deeringia plants typically grow to a height of 6-10 feet, with a spread of around 4-6 feet. They have glossy, dark green leaves that are ovate or elliptic in shape, measuring 2-5 inches in length. The flowers are tubular, with five petals that are fused at the base, and come in shades of white, pink, or red.
