Taxonomic Information

Appearance

Thysanocarpus plants are usually small, growing to a height of around 15-30 cm. The leaves are simple and alternate, and they may be hairy or smooth. The flowers are small and white or yellow, and they are arranged in clusters at the end of the stems. The interesting seed pods are long and narrow, with a thin, papery membrane that is wrapped around the seeds. When the pods dry out, they split open along the membrane, releasing the seeds. The pods have a distinctive curly shape that gives the plant its common name, fringepod.

Care Guide

Thysanocarpus plants prefer well-drained soil and full sun. They are drought-tolerant and do not require frequent watering. If you wish to fertilize your plants, use a low-nitrogen fertilizer in the spring. Thysanocarpus plants are hardy in USDA zones 5-10. They can be grown from seed, which should be sown in the fall or early spring. To propagate the plants, collect the seeds in the fall and sow them in pots or directly in the ground.

Common Pests & Diseases

Thysanocarpus plants are generally healthy and not prone to many pests or diseases. However, they may occasionally be attacked by aphids or spider mites.

To prevent damping off, avoid overwatering and keep the soil well-drained.
