Decumbent St. Andrew's Cross

Hypericum hypericoides (hy-PER-ih-kum hy-per-ee-KOY-deez subspecies mul-tee-KAW-lee)

Family: Hypericaceae Native Herbaceous (1-3 ft)

Reclining St. Andrew's Cross is a native perennial, low-growing, shrub in the St. John's Wort Family (Hypericaceae). In nature, it is found in the central and eastern United States and is common to the dry woodlands of the North Carolina mountains and Piedmont. The stems grow up to 1 foot long and are erect to recumbent, many-branched from the base and matt forming. It can be found usually growing in somewhat acidic sandy loams in forest edges, streambanks, pond margins, roadsides, and disturbed areas. The Genus name is from the Greek: hyper, meaning “above” and eikon, meaning “image,” referring to the practice of hanging these flowers above icons. The subspecies name multicaule means many-branched. The species epithet stragulum refers to the reclining, straggling habit of this plant. This plant will tolerate most moist to dry well-drained soils in full sun to partial shade. Best blooming occurs in full sun. The small bright yellow flowers appear during the summer and attract pollinators. It reproduces by seed. Use this plant in the native pollinator garden, meadows, forest edges and pond edges. Diseases, Insect Pests, and Other Plant Problems: No significant problems. It is fairly short-lived.
