I found a really great Rhus (Sumac) clump style Bonsai photo on insta-stalker. I like this Bonsai composition. Its different and it looks great. I am not sure what type of Sumac it is, it does seem to look like a Smooth Sumac, but that is just a guess on my part. I hope the photo will give you some great ideas.  I have added the photo to the Sumac Bonsai, Deciduous Bonsai and Bonsai Tree Information pages.
