Hypericum calycinum, commonly known as Aaron's beard or St. John's wort, is a rhizomatous geophyte or subshrub in the family Hypericaceae. Native to southeastern Europe and southwestern Asia, it is known for its large, bright yellow flowers and evergreen foliage. The plant prefers temperate climates and can spread rapidly through its rhizomes.
Hypericum calycinum is relatively easy to care for. It thrives in bright, direct sunlight and prefers moderate temperatures. The plant should be watered when the soil partially dries out, and it benefits from moderate humidity levels. It is well-suited for outdoor growth in temperate climates.
土壤
This plant prefers well-draining loamy soil. It can tolerate a range of soil types but performs best in soil that retains some moisture without becoming waterlogged. Good drainage is essential to prevent root rot.
肥料
A balanced fertilizer with an N-P-K ratio of 10-10-10 can be applied during the growing season to support healthy growth. Fertilize once a month during the spring and summer for best results.
换盆
Hypericum calycinum can be repotted if necessary, although it is typically grown outdoors. If grown in a container, repotting should be done in the spring when the plant shows new growth. Choose a slightly larger pot with good drainage and fresh soil.
传播
The plant can be propagated through division or cuttings. Division is best done in the spring or fall, while cuttings can be taken during the growing season. Ensure that cuttings have at least a few nodes and are placed in a moist, well-draining medium.
修剪
Pruning is beneficial for maintaining the shape and health of the plant. Prune in late winter or early spring before new growth begins. Remove any dead or damaged stems and trim back to encourage bushier growth.
毒性
Hypericum calycinum is generally non-toxic to pets and humans. However, as with any plant, it is best to prevent ingestion by pets or children.
额外的
Hypericum calycinum is a hardy plant that can tolerate a range of conditions, making it an excellent choice for ground cover in gardens. It is also deer-resistant and can help control erosion on slopes.
