6. How far up?

Weeds will sprout at any height within the tree canopy, wherever falling leaves and other debris are trapped by branches and crotches, and whenever seeds can reach the resulting humus accumulations. It's a tough environment that's well suited to fast growing, weedy plants and shrubs, prone to drying out in summer and remaining wet all winter.

I don't know about esthetics-- these are wild trees in dense forest. Really, they're most beautiful from within the tree crowns themselves. Many arboreal humus accumulations are invisible from the ground, hidden within the high canopy.
