St John's Wort - Hypericum perforatum
150 Seeds.
Sow Spring or Autumn, seeds can take up to four weeks to germinate.
Hardy perennial.
Height 30-90cm (1-3ft), spread 30cm (1ft).
Tolerates any soil but can be invasive in light soils; prefers a sunny position or light shade.
When growing St. John’s Wort from seed, the best time to start germination is 6 to 8 weeks before the last frost. You can either start germination indoors, or you can directly sow your seeds in your garden.
Just place a few seeds in each spot about 1 cm (½”) deep. The soil needs to have to be at a fairly warm temperature of 70 F, and keep them away from bright light in order for them to germinate. Germination will take approximately 10 – 20 days. Keep the soil moist during germination, by misting them with water in a spray bottle daily.
The small leaves are stalk less, covered with tiny perforations, which are in fact translucent glands. The scented yellow flowers with black dots appear in summer.
