Great St. John's Wort Seeds (Hypericum pyramidatum) reaching up to 152.4 centimeters in height with good-sized blossoms and is the largest of all St. John's Worts! The blooms are bright yellow and star-shaped. These wildflowers are quite showy, and the carefree plant is very easy to grow!

This species of St John's Wort features tall plants, and large yellow flowers. The perennial is very easy to grow and is often grown for medicinal purposes. It produces a lot of seed, so spreads readily by reseeding.

This flower earned its name by blooming at the time of the summer solstice when the traditional feast of St. John takes place. Its reputed power to chase away evil comes from its effectiveness as an herbal treatment for depression and melancholy, which at one time were believed to be a sign of demonic oppression. The species name "punctum," meaning "punctured," alludes to the tiny black spots on the leaves and blossoms; in reality, these are not holes but glands that contain the oils of the plant. The term "wort" comes from Old English, referring to a plant commonly used for medicinal or herbal purposes.

How To Grow

Sowing: Directly sow Great St. John's Wort seeds in the fall, pressing the tiny seeds into the surface of rich soil and sprinkling a very thin layer of soil on top; this seed requires light to germinate. Mixing the seed with a small amount of sand may aid in seed distribution. For spring planting, mix the seed with moist sand and store it in the refrigerator for 60 days before planting. To start indoors, sow Great St. John's Wort seeds in a flat, keeping the soil lightly moist and at a temperature of 18-21 degrees Celsius until germination. Transplant seedlings outdoors as soon as they can safely be handled.

Growing: Keep seedlings watered until they have become established. Mature plants also thrive with regular moisture and do well in well-drained, moist soil; they do not grow well in drought conditions. Eventually, this plant may spread by rhizomes, though it does not become aggressive.

Harvesting

These flowers do not fare well when cut, so it's best to enjoy them in the garden.

Seed Saving

Once the flowers have wilted, pointed seed pods will form and transition from green to brown as they mature. When fully ripe, these pods will split open at the top, exposing small brown seeds. To harvest, shake the open pods over a container to collect the seeds. Store the cleaned Hypericum Pyramidatum seeds in a cool, dry location.
