Yucca filimentosa 'Excalibur' Seeds

Oregon Blue/Grey form - Cold Hardy -20F!

The Excalibur Adams Needle is a rare and beautiful hybrid species of yucca that can grow a single trunk or multiple trunks and dense but thicker (when compared to regular Adams Needle) crown of foliage, 4-6 ft. tall; Stiff but playable, blue-grey (far more blue than regular Adams Needle) leaves are 1-2 ft. long, have slightly drooping tips and together create a large circular canopy; old leaves persist on trunks for many years unless removed. Striking clusters of creamy-white flowers occur on 2-3 ft. long stalks well above the foliage in early spring.

Yucca filimentosa 'Excalibur' tolerates heat, aridity, humidity, sun, wet, and temperatures to 0°F or below all the way to 100+. It develops striking foliage character and colorful flower clusters that make it popular as an accent plant in southwestern and Mediterranean style gardens, perfect for xeriscaping! It is often grown with other cacti and succulents, in raised planters and around boulders.

These particular seeds were collected from our own parent trees in the high desert of Central Oregon, U.S.A. This variation seems to produce a striking blue/grey color foliage that seem to glow in the sun! Parent trees have been growing in the cold high desert where they routinely see temps as low as -10F! The parent trees have survived -12F with NO DAMAGE whatsoever and we think these plants are cold hardy to well below -20F... zone 5!! These even seem to grow much faster than standard Adams Needle!

When it matures, it is a colorful flowering accent shrub for courtyard and southwestern plantings due to its large flower inflorescence. Monthly deep watering from spring through fall will enhance its spring flowering cycle and help maintain good foliage character.

These seeds are fresh and ready for planting!
