In the garden

Yucca gloriosa 'Nobilis' originates from the southeastern United States and establishes as a multi-stemmed evergreen shrub with a clearly defined, upright outline. It typically grows to about 1.8 m and produces tall flower panicles of white, bell-shaped blooms in mid to high summer (June to August). Plant in a sunny, sheltered spot with free-draining soil; it performs best in sandy or loamy mixes that do not stay waterlogged. Soil should be kept moist but well-drained rather than persistently wet. Exposed full sun encourages compact growth and reliable flowering. In the UK it is rated H6 (very hardy), making it suitable for most gardens except the coldest, most exposed sites. Use Yucca gloriosa 'Nobilis' in structured borders, gravel or rock gardens and xeriscape schemes where its upright form provides contrast with lower planting. Give it room to form a clump and beware of its sharp leaf tips and toxicity when siting near paths or play areas. Expect conspicuous white flower spikes above the foliage in June to August, which work particularly well against pale stone or gravel surfaces.
