St. Peter's-Wort, Atlantic St. Peter's-Wort
Hypericum crux-andreae (Ascyrum stans)

Hypericaceae

St. Peter's-wort is a small, upright shrub native to moist sandy woods, pinelands, stream banks, wet prairies and pond margins from Southeast and East Texas (and the very eastern edge of North Central Texas) east to Florida, and north to Pennsylvania and New York. It grows from 1 to 3 feet tall, a slender shrub with opposite, pale green oval to oblong leaves and shedding bark on older wood. The light yellow flowers appear from June to October. In its native habitat it is usually found in semi-shade. St. Peter's-wort looks much like St. Andrews's cross, H. hypericoides, and their habitats sometimes overlap. H. crux-andreae has broader leaves, up to 3/4 inch wide and 3-4 styles, whereas H. hypericoides has only 2 styles and narrower leaves only up to 1/3 inch wide.
