On a recent trip to Hawaii I noticed a lot of palms in full sun that would get torched in full sun back home (Arizona). Yet my body seems to suffer the oppsite when I go to Hawaii I get burned much faster than in AZ. Why? I assume it has something to do with the lattitude and maybe more cloud cover in HI???? The V Merrillii are in full sun all over the place in HI but mine here in AZ is in almost full shade. Thanks
