Donald, you answered the question I had about variegated ones. They appear to prefer shade during the hottest part of the day, 11:00 AM till 4:00 PM. Since all mine are outside and are never brought in as "houseplants", they receive lower levels of sun as they emerge in the spring and then as they grow, the amount of sun slowly increases. This is what one would do to acclimate their houseplants to sun, moving them from inside to outside. Mother Nature "acclimates" mine.
