Beautiful cycad- has blue-green-silvery leaves that are perfectly arranged in a almost mesmerizing geometric overlapping pattern. This is a moderately fast growing cycad and there are enormous plants in Mexico that tower over a person's head. However, in cultivation, a plant with several feet of trunk is fairly old and considered a specimen.
