Triphysaria plants are hemiparasites, which means they obtain some of their nutrients from other plants.

The flowers are typically arranged in a raceme, which is a type of inflorescence with flowers along a central stem. The leaves are opposite, simple, and often have a purplish tinge. The stem is usually branched, and the plant has a taproot.
Care Guide
Triphysaria plants are relatively easy to care for, and they require minimal maintenance. Here are some tips for taking care of these plants:
- Water: Triphysaria plants prefer moist but well-drained soil. Water them regularly, but avoid overwatering as it can lead to root rot.
- Fertilization: These plants do not require fertilization as they obtain some of their nutrients from other plants.
- Soil: Triphysaria plants grow well in sandy or loamy soil that is rich in organic matter.
- Sunlight: These plants prefer partial shade to full sun.
- Hardiness Zones: Triphysaria plants grow well in USDA hardiness zones 9-11.
Common Pests & Diseases
Triphysaria plants are relatively pest and disease-free. However, they may occasionally suffer from the following:
- Aphids: These insects suck sap from the plant and can cause stunted growth and yellowing of leaves. Use insecticidal soap to control aphids.
- Root Rot: Overwatering or poorly drained soil can lead to root rot, which can cause the plant to wilt and die. Improve drainage and reduce watering to prevent root rot.
