St John's Wort

Hypericum perforatum. Popularized in medieval legends as an antidote for evil spirits, this European perennial has prolific 1"-wide, stamen-studded, golden-yellow flowers amidst deep emerald leaves on upright, strong, branching stems. Easily grown, St. John's Wort may be started indoors 6 to 8 weeks prior to transplanting outside after the last spring frost date, or it may be direct-sown after the last possible frost date. Once established, it is drought-tolerant and matures into an indestructible butterfly-friendly shrub. Also known as Tiptons Weed, Chase-Devil or Kalmath Weed, its popularity as a medicinal herb skyrocketed in the 1990s when it was said to be a natural remedy for depression. Perennial. Hardiness zones: 4-8. Height: 12" to 36". (OP.)
