Circaea

Description

Circaea is a genus of plants that belongs to the Onagraceae family. It consists of about 15 species of annual or perennial herbs that are found in the Northern Hemisphere. The name “Circaea” comes from Circe, a Greek goddess who was known for her magic powers. These plants are also known as enchanter’s nightshade because of their ability to heal wounds and cure diseases.

Taxonomic Information

Appearance

Circaea plants are either annual or perennial herbs that grow up to 60 cm tall. They have alternate leaves that are ovate to lanceolate in shape, and they are serrated at the edges. The flowers are small and white or pink in color, and they bloom in the summer. The fruit is a bur that has two hooked prickles, and it splits into two parts when it is ripe.

Care Guide

Circaea plants prefer moist, well-drained soil that is rich in organic matter. They also require partial shade to full shade and can grow in hardiness zones 3 to 9. Water them regularly, but avoid overwatering as it can lead to root rot. Fertilize them once a month during the growing season with a balanced fertilizer. Prune them in the fall to remove any dead or damaged branches.

Common Pests & Diseases

Circaea plants are relatively pest and disease-resistant. However, they can be affected by powdery mildew, rust, and leaf spot. These diseases can be prevented by providing good air circulation and avoiding overhead watering. Aphids and spider mites can also infest Circaea plants, and they can be controlled with insecticidal soap or neem oil.
