Answer: Hostas have the reputation for reverting back to solid green if the growing conditions don't suit them or if they have been divided and replanted. I know it sounds odd, but it is quite common with certain hybrids. You might learn to like the ones that have reverted to green but if not, you can attempt division of the variegated ones again. Dig and divide them in late winter while they are still dormant, then plant in the new spot. Hope this strategy works for you!
