Tips for Care:

Hypericum needs to be planted in full sun and a touch of part shade/afternoon shade (especially in warmer climates). Plant in well-drained soil for the best growth possible because St. John’s Wort cannot tolerate wet feet! In cooler parts of the country, Green Hypericum may die back to the ground in harsh winters, but each spring, it will come back strong and true.

A generous 3-4 inch thick layer of mulch retains moisture and insulates the root system from heat and winter’s chill. St. John’s Wort blooms on new wood, so prune while dormant to control the size and shape however, these really do their best in locations where they’re allowed to be themselves.
