Taxonomic Information

Appearance

Tenaxia plants have a unique appearance, featuring elongated leaves with a glossy sheen. The leaves are lance-shaped and grow up to 6 inches long, with a width of 1 inch. The plant produces small white or pink flowers that grow in clusters at the tips of the stems. The flowers bloom in late spring and summer and are followed by small, brown, capsule-like fruits that contain tiny seeds.

Care Guide

Tenaxia plants are relatively easy to care for and can thrive in a variety of conditions. Here are some tips for proper care:

• Water: Water the plant regularly, keeping the soil moist but not waterlogged. Allow the soil to dry out slightly between watering.
• Fertilization: Fertilize the plant once a month during the growing season with a balanced fertilizer.
• Soil: Plant Tenaxia in well-draining soil with a pH between 5.5 and 7.5.
• Sunlight: Tenaxia prefers bright, indirect sunlight, but it can tolerate some shade.
• Hardiness Zones: Tenaxia is hardy in USDA zones 10-11.

Common Pests & Diseases

Tenaxia plants are generally resistant to pests and diseases, but they can still be susceptible to a few common issues:

• Spider mites: These tiny pests can cause yellowing and curling of the leaves. Treat with insecticidal soap.
• Leaf spot: This fungal disease causes brown spots on the leaves. Remove infected leaves and treat with a fungicide.
• Root rot: Overwatering can lead to root rot, which can cause the plant to wilt and die. Reduce watering and improve drainage to prevent this issue.
