I take the plastic palm tops that you get from cake supply companies or china,I take them off the trunks on some and glue them ontop of varied length dried flower stems,and some I keep on the trunks ,base and paint a flatter color,and also use golden yarrows (dried flowers ) for high canopy trees. heres a picture of one I made for my india games,and they are cheap. The golden yarrows tops start to slowly fall apart after 12 years,so then I just put palm tops on them. I like them also because it's easy to do ,I am not a patient modeler,so this works for me.
