Taxonomic Information

Appearance

Gunneraceae plants are known for their large, lush leaves that can grow up to several feet in diameter. The leaves are usually rounded or heart-shaped and have a distinctive texture that is rough to the touch. The flowers of Gunneraceae plants are small and clustered on long spikes that rise above the foliage. The flowers are usually greenish-yellow or reddish-brown in color.

Care Guide

Gunneraceae plants require consistent moisture to thrive, so watering is a crucial part of their care. They prefer soil that is rich in organic matter and slightly acidic. Fertilize the plants once a month during the growing season with a balanced fertilizer. Gunneraceae plants prefer partial shade to full sun, but they can tolerate some shade. They are hardy in USDA zones 7-10.

Common Pests & Diseases

Gunneraceae plants are susceptible to a few pests and diseases. Spider mites and aphids can be a problem, especially if the plants are grown in dry conditions. Fungal diseases such as powdery mildew and rust can also occur if the plants are kept too moist. To prevent these problems, keep the plants well-watered but not waterlogged, and prune away any infected leaves or stems.

Habitat

Gunneraceae plants are native to the wetlands and moist forests of South America, where they grow along rivers, streams, and in boggy areas. Some species are also found in New Zealand and Southeast Asia. They prefer moist, well-drained soil and are often found growing in areas with high rainfall.
