Coastal Ground cherry (Physalis angustifolia) is an herbaceous perennial that produces yellow to orange berries, that look similar to tomatillos, but are only edible when fully ripe. If unsure, do not consume the fruit because they are toxic when they are not ripe. Coastal Groundberry requires full sun; it is a species of flowering plant that is a member of the nightshade family. Plant it in moist, well-drained sand, loam or clay. It is the larval host for the Subflexus Straw moth.
