 I can't remember for sure, but I may have bought both of mine, the Paper Bark Maple, which is acergrisium, it and the Parodia mail order because none of the local people were handling it. Parodia can take full sun. I got one at the office that's growing in full sun. It's not having a problem at all, but it's just one of those that if you let it get on the dry side, it probably would at least have some cosmetic burn to it that you wouldn't want to have.
