The Yucca Rigida produces flat, blue-gray leaves. As the lower leaves of the Yucca Rigida mature, they turn brown and fall down parallel to the trunk and become attached to the trunk by a glue-like material that is found underneath each leaf. The beautiful Yucca Rigida landscape specimen can form several branches at the top covered with blue-gray leaves like grass filaments, with a height up to 15 feet tall. Yucca Rostrata 'Rigida' grows to huge heights. You can buy your Yucca Rostrata 'Rigida' from the TyTy Nurserytoday. A colony of Yucca Rostrata is often used in commercial xeroscapes. Yucca Rostrata do well in dry soils and are very drought tolerant.
