As far as height goes, how high d'you want to go? At the mo I scour the gardens for grasses (pennisetum, china etc) but if I need to go higher still I start cutting the trees!! Well, at least some branches/twigs, take the leaves off if I know they don't last and build up the optical illusion of height. I LOVE using apple trees twigs/branches, especially those from an old apple tree. They have so much movement and character! Fall and winter stuff is dominated with beautiful craggly apple tree twigs!
