Nelson's blue bear grass looks like an arborescent yucca but with finer blue foliage.
From the Mexican state of Tamaulipas comes this really cool and far-out bear grass . This tree-like succulent.becomes 20 feet tall or more, 8 feet in diameter. Slowly develops multiple heads.. When the 10'-12' tall clumps mature, a 4' tall bloom stalk will rocket forth with thousands of tiny white flowers!
