Tolerates sun in central Arizona and shows no signs of frost damage down to at least 25F. Supplemental water will allow it to grow faster with fatter, more robust leaves.

The larger and more separated leaves show even more the white pattern left by the leaves that were once on top during development... a very show plant. Slow to sucker, but it seems to.
