Catching up to this a little late, but hey, cool work! Grape vines are woody, but they look more like the fern plan than the plum tree. Or, use the plum tree, but hide the trunk and most of the branches. To stand next to them, grape vines come perhaps 4 feet high. Taller with assistance (stuff to climb on). Ferns are probably the best way to go for a base model to work on. and p.s. Glad you're enjoying the goodies! :)
