A lovely and tough yucca relative from the Southwest into Mexico, the Red False Yucca is super drought tolerant, though excepting of summer water, architectural and has a look somewhere between a grass and a yucca. Closely related to the yuccas and agaves but a separate genus these will bloom every year with bright neon red to pink flowers that delight the hummingbirds. Very easy to grow in almost any well draining soils in full sun and also surprisingly hardy, all the way down to -20F!

Perhaps the most dramatic focal point one could plant in their garden, Sapphire Skies Beaked Yucca will cause even the most botanically blind among us to drop their jaws! The powdery blue thin leaves radiate from the center to form a perfectly round orb, almost like a freeze frame of a firework exploding! The ‘Sapphire Skies’ variety was selected by the great Sean Hogan of Cistus Nursery from a seed batch for its particularly blue foliage.

In youth it forms a nice little round mound of its gorgeous foliage but in a few years time it will begin forming a trunk and eventually rise to 8-10′ tall! But wait there’s more! It will eventually send out those soft elegant stalks of 4′ tall yucca flowers that whisper to the wind of desert magic and enchantment. While the incredible architecture of this plant may have you dreaming of the sky islands of Arizona and Mexico it is surprisingly frost hardy all the way down to Zone 5! One specimen is even thriving in the Denver Botanical Garden. Its only requirements are good sunlight and relatively well draining soil and, if possible, a slightly alkaline soil. We encourage everyone to plant this incredibly striking and tough plant wherever they need an exclamation point in their garden.

A great color to add to the garden, (who doesn’t need a little more purple and blues?) the Magenta Magic Yucca was discovered at Briggs Nursery and has proven itself one of the easiest yuccas to grow. Yucca aloifolia is actually native to the Atlantic coast from southern Virginia all the way down into Mexico! A great accent plant in the garden and useful for adding a different shade of color to spice things up!

A fantastic selection of Adam’s Needle Yucca, the Excalibur Yucca features gorgeous grey-blue foliage and an extraordinary amount of the beautiful little white filaments that add such a wonderful texture to its already textural rosette. Flower spikes emerge in late spring and hold huge clusters of white flowers for months! Leaves are soft and bendy rather than sharp and poky so can easily be planted near a pathway
