It belongs to the Boraginaceae family and is known for its large, rough leaves and striking purple flowers. The plant can grow up to 3 meters tall and is often used in ornamental gardening for its dramatic foliage and blooms.

土壌
Wigandia urens prefers well-draining loamy soil with a slightly acidic to neutral pH. The soil should be kept moderately moist but not waterlogged. Good drainage is essential to prevent root rot.
肥料
A balanced fertilizer with an N-P-K ratio of 10-10-10 should be applied during the growing season to support healthy growth. Fertilize every 4-6 weeks for best results.
植え替え
Repotting is necessary when the plant outgrows its container. This is typically done in the spring. Choose a pot that is one size larger and ensure it has good drainage. Gently remove the plant from its current pot, loosen the roots, and place it in the new pot with fresh soil.
伝搬
Wigandia urens can be propagated through seeds or cuttings. For cuttings, take a healthy stem cutting in the spring or early summer, dip it in rooting hormone, and plant it in a well-draining soil mix. Keep the soil moist and place the cutting in a bright, indirect light until roots develop.
剪定
Pruning is essential for Wigandia urens to maintain its shape and encourage new growth. Prune in the late winter or early spring before new growth begins. Remove any dead or damaged branches and trim back overgrown areas to promote a bushier appearance.
毒性
Wigandia urens is not known to be toxic to pets or humans. However, its leaves are covered in fine hairs that can cause skin irritation upon contact, so handling with gloves is recommended.
追加
Wigandia urens is a striking addition to any garden with its large leaves and vibrant flowers. It can be used as a focal point in landscape design. Ensure it has enough space to grow and spread, as it can become quite large.
