Yucca rostrata 'Sapphire Skies'

Beautiful powder blue seed selection made by Sean Hogan of Cistus Nursery, a rounded fountain of narrow, pointed, unarmed leaves slowly to 48 inches or more in warmer climates. Midsummer clusters of white flowers on yellow orange stems are loved by hummers on mature plants. needs well drained soil, warmth, sun and occasional to infrequent water. Deer resistant. Evergreen architectural treat!

The short, powder-blue, succulent "swords" of this, one of the hardiest of the trunk forming (to 4' tall) Yucca, make an elegant statement. S/GDr

Hardy trunk forming. Thin blue leaves.

This selection of the super hardy Y. rostrata has excellent baby blue coloured foliage forming a dome of textural, succulent blue. It will grow to about 16 inches in four years but over time it will develop a trunk and form an amazing, upright, unbranched tree to about five feet. (I have a five footer in my garden that has sailed through six cold winters and it's spectacular!) Needs excellent drainage in full sun.

Narrow blue leaves needs gritty dry site in sun

A beguiling sculptural rosette of powder blue, thin pointed blades, year-round good looks and exceptional hardiness is what this shrubby, fine textured Yucca has to offer. Relatively short, flexible leaves forge a luminous specimen well suited for a vessel or the dry garden. Selected by Sean Hogan of Cistus Nursery from seed he collected in northern Mexico, it will eventually form an upright unbranched plant that prefers to bake in a hot sunny spot with sharp drainage and alkaline soil, while protection from excessive cold-season water and wind helps ensure a successful overwintering.

Yucca Rostrata will grow a trunk up to 18 feet tall and looks similar to a palm tree. They are slow growing, about 2 to 6 inches of trunk each year once the plant begins to produce a trunk. The key to growing this plant is good drainage. It likes full sun and dry soil that quickly drains. We add lime stone gravel to our plants which helps with drainage. Foliage: Thin blue foliage Flowers: White flowers on 6 foot stalk Height: 15 to 18 feet

A gem of a Yucca! Makes a fantastic focal point with flexible blue leaves that look like fireworks. This thornless Yucca originates in Northern Mexico. A blue-leaved variety selected by Sean Hogan of Cistus Nursery in Oregon, from a batch of seedlings. Thanks Sean! I can’t wait to grow ‘Sapphire Skies’ in a large pot on my patio or maybe in the garden, complimented by yellow-flowered Xanthisma texana. Eventually developing a trunk & growing to 10’ tall & 3’ wide. Also produces a tall spike of creamy-white flowers in late Summer that Hummingbirds love. The foliage is green when young but will get bluer as it ages. A great fire-resistant plant for those of you in fire-prone areas. Needs excellent drainage.

An elegant, short leaf selection, with gorgeous powder blue-colored leaves which hold their color year-round. Over the years it will form an upright, unbranched tree with a stout trunk to about 4'. The hardiest of the trunk forming Yuccas. Another rare and exciting plant find brought to us from our friends at Cistus Nursery.

Narrow upright blue gray leaves on this selection create a pleasing contrast with other textures in the garden.

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!).
