plant sale text: Bushy St. Johns-wort is a Southeastern native shrub that adds lively color to the summer garden. Its growth habit is multi-branched and fine-textured. In midsummer, profuse small yellow flowers bloom for many weeks. Although easily grown, bushy St. John's-wort is relatively uncommon. The genus name Hypericum is derived from the Greek and means 'over an apparition', referring to the common belief that St. John's-worts repel evil spirits. The Hypericum genus supports up to 20 lepidoptera species.
