Another species of Yucca commonly cultivated, and long since 
introduced into our gardens. When in a good situation it flowers 
freely. The figure is from a specimen which flowered in the 
Royal collection at Kew. I have grown it for many years, and 
find it quite hardy. For treatment see observations on culture,
