Plant Details

A Cistus introduction. Although Yucca rostrata is one of the most gorgeous species available, and definitely one of our top 500 favorite plants, it is exceedingly slow to reproduce from offsets, seed is difficult to come by, and seedlings vary as to their...blue-osity. Yucca rostrata 'Sapphire Skies' is a selection from one of our collections in the early 90s in northern Mexico, out of a seed batch of stunning blue-leaved plants. Through the magic of tissue culture, we now have a reliable source. These vigorous young plants quickly form a 3 ft, multi-leaved rosette of nearly jade-blue, forming 3 to 4 ft plants in 7 or 8 years under good conditions, eventually to 10 ft or more. Excellent container plants, providing fine architecture, or repeated in the dry garden and looking of dusty blue fireworks from a distance. Particularly beautiful reflected in late afternoon/evening light. Full sun to dappled shade. Not particular about soil, excepting standing water. Some supplemental irrigation in dry summer places. Frost hardy in USDA zone 7; has been successful in zones 5 and 6 including the Denver Botanic Garden (Really!).
