Raoulia

Raoulia is a genus of plants belonging to the Asteraceae family, commonly known as the daisy family. These plants are native primarily to New Zealand, with a few species found in Australia. They are known for their distinctive silvery or greyish foliage, often forming dense mats or cushions in alpine and subalpine environments.

Raoulia species are adapted to harsh conditions, including strong winds, intense sunlight, and poor soils. Their leaves are typically small and covered in fine hairs, which help to reduce water loss and protect them from UV radiation.

Several species of Raoulia are popular in horticulture, particularly in rock gardens and alpine plant collections. They are valued for their unique textures and colors, which provide year-round interest. Popular species include Raoulia australis and Raoulia hookeri.

The conservation status of various Raoulia species varies, with some being relatively common and others considered rare or threatened due to habitat loss and other factors. Conservation efforts are underway to protect these unique plants and their fragile ecosystems.
