St John’s Wort (Hypericum perforatum) - 100 Seeds
•American Grown Seeds
•USDA Zones: 4-8
Shrubby St. John’s-wort is a very small, mound-shaped, deciduous shrub, to 3 ft. tall, with dense, upright branching and exfoliating, red to purple bark. Smooth, dark- to blue-green, fine-textured foliage becomes yellow-green in fall. Large, yellow flowers occur singly or in few-flowered clusters. A dry, dehiscent, three-valved capsule persists all winter. This shrub adapts to a variety of moisture regimes and is even flood tolerant. It has no serious disease or insect problems. This species is pH adaptable but does extremely well in calcareous sites.
St. John's Wort seeds are easy to grow. Plant the herb seeds indoors 6 - 8 weeks before the last frost, or outside after the danger of frost has passed. Press the Hypericum seeds into the soil, but do not cover it as the seed will germinate better with light. Transplant the Hypericum seedlings when they are 2 - 3 inches tall. The plants will tolerate most any soil conditions but prefer moist and light soils. Fertilizer is only necessary in the poorest of soils, and water in prolonged drought times. Grow St. John's wort in full sun or partial shade and in moist, well-drained soil of any kind except very alkaline or salty. Space plants 24 to 36 inches apart, and water regularly so that the soil is constantly moist but not sodden.
