Appearance:

Leaves: The leaves of Hypericum kalmianum are typically elliptical or oblong, about 1-2 inches long. They are dark green and arranged in opposite pairs along the stems.

Fruit: After flowering, Hypericum kalmianum produces small, round, berry-like fruits that turn from green to red and eventually black as they mature.

Growing Instructions

Sowing Seeds: Prepare a seed tray or small pots with a well-draining potting mix. Sow the scarified seeds on the surface of the soil and lightly press them down. Cover the seeds with a thin layer of soil.

Watering and Care: Keep the soil consistently moist but not waterlogged. You can cover the seed tray or pots with a clear plastic lid or plastic wrap to create a humid environment. Place the container in a location with bright, indirect light.

Germination: Hypericum kalmianum seeds may take several weeks to a couple of months to germinate. The germination rate may vary, and not all seeds may germinate.

Transplanting: Once the seedlings have grown large enough to handle (usually when they have developed a few true leaves), you can transplant them into individual pots or into a suitable outdoor location. Choose a spot with adequate sunlight and well-draining soil.

Maintenance: Continue to care for the seedlings as they grow, providing regular watering and fertilization as needed. Protect them from harsh weather conditions and ensure they receive appropriate care for their specific requirements.
