Yucca queretaroensis was first discovered in 1989 in the Mexican states of Queretaro and Hidalgo between 3,000' and 4,000' elevation. Yucca queretaroensis is similar in appearance to Yucca linearifolia, but has a thicker trunk (10' tall) and a square green leaf compared to the flat leaf of Yucca linearifolia. A 30" flower spike of white bells will top the clump once it reaches maturity. Yucca queretaroensis makes a stunningly beautiful clump and no doubt will be hugely popular once it becomes more widely available. This is so new to cultivation, we don't know the limits of the cold tolerance yet, but we've seen no damage at 14 degrees F.
