Nodding Texas Yucca (Yucca cernua) was discovered in the early 2000s in the wilds of East Texas. It has spiky blue-green foliage which creates a mound 2' tall by 4' wide. Once mature—after 5 to 10 years, generally—it blooms in spring with a huge 8+ foot tall flower spike of pendulous creamy-white flowers. In it's native habitat, it grows in dry, fast-draining, partly-shady conditions under Loblolly Pines (Pinus taeda).
Grown in-house from seed; not wild collected.
Minimum temperature: 0° F, possibly colder but untested
