Appearance
Sebaea plants typically grow to a height of 15-30 cm, with a spread of 10-20 cm. They have slender stems that are often branched, with small, lance-shaped leaves that are arranged in pairs. The flowers are usually less than 2 cm long and are borne in terminal clusters. They have five petals that are fused into a tube, and five stamens that are attached to the petal tube. The flowers are usually pink, purple, or white, with some species having dark markings on the petals. The fruit is a small, dry capsule that splits open to release tiny seeds.
Care Guide
Sebaea plants are relatively easy to care for and can be grown in containers or in the ground. Here are some tips to help you care for your Sebaea:
- Water: Water your Sebaea regularly, keeping the soil moist but not waterlogged. Allow the soil to dry out slightly between waterings.
- Fertilization: Fertilize your Sebaea once a month during the growing season with a balanced, water-soluble fertilizer.
- Soil: Sebaea plants prefer well-draining soil that is rich in organic matter. Use a potting mix that is specifically formulated for flowering plants.
- Sunlight: Sebaea plants prefer bright, indirect sunlight. They can tolerate some direct sunlight, but too much can scorch their leaves and flowers.
- Hardiness Zones: Sebaea plants are hardy in USDA zones 9-11. They can be grown as annuals in cooler climates.
Common Pests & Diseases
Sebaea plants are relatively pest and disease-free, but they can be susceptible to root rot if they are overwatered. Here are some common pests and diseases that can affect Sebaea:
- Root rot: This is a fungal disease that can cause the roots to rot and the plant to wilt. To prevent root rot, make sure to water your Sebaea properly and avoid overwatering.
- Aphids: These small, soft-bodied insects can suck the sap from the leaves and flowers of Sebaea plants, causing them to wilt and die. To control aphids, spray your plants with a mild soapy water solution.
- Spider mites: These tiny, spider-like insects can spin webs on the leaves of Sebaea plants and suck the sap, causing the leaves to yellow and die. To control spider mites, spray your plants with a solution of water and neem oil.
Habitat
Sebaea plants are native to southern Africa, where they grow in a range of habitats, from grasslands to forests. They prefer well-draining soil and bright, indirect sunlight. Some species of Sebaea are endangered due to habitat loss, so it is important to protect their natural habitats.
