Well, the ones here are often seen growing on electric and telephone lines, in full sun. The ones I've brought home before I've put in a lot of light but no direct sun and they all died eventually. I was looking at the ones in the trees above my favorite coffee shop and they are in open leafed trees and usually near the crotch with at least partial sun. I may move this pile to an area with partial sun but open to the rain and see how that goes. The last few days it hasn't been an issue because while we have sunny mornings, it has rained every afternoon and evening for weeks.
