Raoulia lutescens is a type of cushion plant native to New Zealand and is commonly referred to as "mountain cotton." The plant's dense clusters of silver-grey leaves and woolly texture make it an attractive ornamental in gardens and a hardy survivor in alpine environments. Although its scientific name is Raoulia lutescens, it is also known by various synonyms, including Raoulia hookeri, Raoulia tenuicaulis, Raoulia monroi, and Raoulia australis. These synonyms have been assigned due to minor morphological differences among different sub-species of the plant. Regardless of the name, Raoulia lutescens remains a fascinating and worthwhile plant to observe.
