Criss & Rick Thompson 1995. A variegated sport of H. ‘Blue Angel’. Begins in the spring as a white-centered leaf that grows greener with light and dark variation, then ends as a medium grey-blue, still with swirls of variegation based upon how much light it does/does not receive. In our display garden, we lost a tree a few years back and the later summer colors of our specimen plant lightened as a result. Available potted in 6 quart pots where you can see the variation of leaf color from some pots/plants that look solid green to others with lots of variegation. Leaves look different every year to us. Give some space as it gets big.
