Yuccas are familiar and popular garden plants both here and in America and Europe. Trying to sort out the different species and cultivars can be a bit confusing. The most helpful reference text is Yuccas: Giants among the Lilies by Colin Smith who holds the Yucca National Plant Collection in the UK. This is published by the National Council for the Conservation of Plants & Gardens which has as its patron HRH The Prince of Wales.
Many Yuccas are very cold hardy and will tolerate freezing conditions but the main requirement is that the soil is well drained around the roots .They make dramatic accent plants in landscape designs and contrast well with fine leafed grasses and soft perennials . They were used in this way by the famous garden designer and writer Gertrude Jekyll.
2017 update: I still have a limited number of varieties available though their popularity is less now than in previous years.
