More About St John's Wort...

St John's Wort (the species), Hypericum calycinum, is a stoloniferous groundcover plant that produces very unique and beautiful, large, saucer-shape yellow flowers that have bushy center stamens with reddish anthers. The flowers appear singly or in groups of 2-3 and cover the plant in summer. Oval to oblong leaves (to 4" long) are rich green in sun but are a lighter, yellowish green in shade. Sometimes commonly called Aaron's beard or creeping St. John's Wort this species has been used since ancient times in the treatment of wounds and were apparently gathered and burned to ward off evil spirits on the eve of St. John's Day, thus giving rise to the genus common name of St. John's wort.

St John's Wort is easy to grow and maintain in a wide range of conditions. It flourishes in average, medium, well-drained soil in full sun to part shade. It really thrives on sandy soils in full sun. The plant is less floriferous in part shade. In warm winter climates the plant will be evergreen. It usually dies to the ground or suffers some tip dieback in cold winter climates, but blooms on new growth and comes back nicely each spring. In areas where it does not die in winter, shear or mow plants in late winter or early spring every 2-3 years to renew and induce new growth. Spreads rapidly by underground stems and can spread aggressively in ideal growing conditions. Plant 18" apart for use as a ground cover.

St. John's Wort is esecially useful as a groundcover or in border fronts and naturalized plantings. It is also good for stabilizing and controlling erosion on embankments or hillsides. Good for planting under trees where it competes well with shallow tree roots.

Allan Armitage calls this "one of the finest ground covers available!"
