Hypericum calycinum (St. John's Wort) is a small, semi-evergreen shrub with screaming bright yellow flowers, 3 in. wide (7 cm), for weeks from mid-summer to mid-fall. Each rose-like flower presents 5 petals surrounding a prominent tuft of bushy stamens and reddish anthers. Borne solitary or in clusters of 2-3 flowers, they appear in such quantities that they literally cover the foliage. Arranged along procumbent stems, the oval leaves emerge chartreuse-bronzed but quickly turn to medium green, dark green, then blue-green - contrasting against the yellow flowers. A popular groundcover thanks to its lush dark green to bluish-green foliage and its golden flowers. Evergreen in warm winter climates.
