It has oval shaped leaves that are hairy, with leaf stalks about the same length as the leaf blades. Flowers are bell-shaped, whitish in color, 6 &#8211; 8mm long form at the leaf axils. These flowers generally have a drooping or nodding appearance. Flowering occurs throughout the year, but is most prolific during summer. The fruit is an elongated or egg-shaped berry\u00a0with a smooth surface. These berries (10-20 mm long and\u00a07-8 mm wide) turn yellow or whitish in color as they mature and each contains several seeds. The seeds are brown to pale yellow in color, flattened, rounded in shape (about 2 mm across), and surrounded in a\u00a0sticky substance<sup>6<\/sup>.<\/p>\n<p><em>Salpichroa origanifolia <\/em>was sold in CA nurseries in the early 20<sup>th<\/sup> century.
