Hypericum × inodorum

Originating from moderately moist environments, St. John's Wort thrives with consistent watering every 1-2 weeks to prevent waterlogging. Typically grown outdoors, it requires more hydration during its active growing season to maintain healthy foliage and blooms.

St. John's Wort does best in spots that receive abundant sunlight for much of the day. It can tolerate reduced light, though this may somewhat impede its growth. In its native range, it prospers in areas with plentiful sun. Excessive exposure can cause leaf scorch, while too little light may lead to stunted growth and fewer flowers.

St. John's Wort is highly adaptable to different climates, from very hot summers to cold winters. However, it still has an optimal temperature range for growth; if temperatures become too high, the plant can suffer heat and humidity stress that may lead to its death. In areas where temperatures near the lower limit of its cold tolerance, providing insulation is important to protect the plant.

Proper timing matters when feeding St. John's Wort. Apply fertilizer in early spring and continue monthly until early summer. Fertilizer promotes attractive blooms and supplies energy during both dormant and active growth periods.

St. John's Wort is a deciduous shrub known for its vibrant yellow flowers and berry-like fruits. To maintain its health and appearance, prune it in early spring by removing dead branches and thinning out one-third of the oldest stems. This practice improves air circulation, encourages blooming, and reduces the risk of disease.
