Taxonomic Information

Appearance

The plants in the Oxera genus are characterized by their large, showy flowers that come in shades of pink, purple, and white. The leaves are typically large and ovate, with a dark green color and a slightly glossy texture. The stems are woody and erect, with a height that can range from a few feet to over 30 feet in some species.

Care Guide

Oxera plants prefer moist, well-draining soil that is rich in organic matter. They also require regular watering, especially during the growing season, but should not be allowed to sit in standing water. Fertilization should be done in the spring and summer months, using a balanced fertilizer that is high in nitrogen. These plants thrive in full to partial sunlight and are hardy in USDA zones 9-11.

Common Pests & Diseases

Oxera plants are relatively pest and disease-free, but they may be susceptible to fungal infections and root rot if overwatered or planted in poorly-draining soil. Aphids and spider mites may also be an issue, but can be controlled with insecticidal soap or neem oil.

Habitat

Oxera plants are found throughout Central and South America, with some species also found in the Caribbean. They grow in a variety of habitats, including wetlands, forests, and savannas, and are often found near water sources such as rivers and streams.
