In the garden
Native to the USA, Yucca filamentosa grows as a clump-forming evergreen with blue-green, strappy leaves and summer flower spikes that bear cream, pendulous flowers. It is a genus Yucca member used for its strong silhouette rather than dense cover. Expect mature plants to stand around 1.2 m and to be a clear vertical accent when in bloom. Plant in a sunny, open site with good drainage; it will tolerate sandy, loamy or clay soils provided they are not waterlogged. Give it full sun exposure and avoid heavy winter wet, as root health depends on free drainage. In UK terms it is fully hardy (H7) and also matches USDA zones 4–10, so it withstands severe winter cold where soils drain well. Handle with care: the foliage can provoke skin irritation, so use gloves and protective clothing when pruning or dividing, and monitor pets since ingestion is harmful. Use Yucca filamentosa as a structural focal point at the back of a sunny border, in gravel beds or where a strong vertical summer display is wanted; its cream flower clusters are most conspicuous from June to August.
