Noteworthy Characteristics
Chrysogonum virginianum, commonly called goldenstar, is a rhizomatous, low-growing perennial which typically forms a foliage mat to 3-4” tall spreading to 18" wide or more. It is native to woodland areas from Pennsylvania to Florida and Louisiana. Star-shaped, daisy-like, bright yellow flowers (to 1.5” diameter) on stems originating in the leaf axils, bloom spring to fall in cool summer climates. In hot summer climates such as St. Louis, bloom is profuse in spring, but usually becomes sparse or stops in the heat of the summer, with a light rebloom occurring in fall. Flowering stems rise above the foliage mat to a height of 8-10" tall. Each flower has five, rounded, slightly-notched, yellow petals and a center tuft of yellow disk flowers. Ovate, toothed, bright green leaves to 3” long.
Genus name comes from the Greek words chrysos meaning gold and gonu meaning joint in reference to the location of the flower stems at the leaf axils (stem joints).
Specific epithet means of Virginia.
Common name is in reference to the star-like shape of the 5-petaled flowers.
