“It turns out the “poison sumac” (Rhus vernix) of my childhood, which I so diligently avoided, wasn’t poison sumac after all, although R. vernix does grow in Indiana.”
This is from my reply to a comment from Steve at Portraits of Wildflowers. Steve reports Rhus trilobata grows in Texas, but Rhus lanceolata is more reliable for bright reds in the fall.
Steve got me going on a Rhus hunt from his comment on making sumac-ade. See my reply on my original post about Rhus and how it adds color to the autumn landscape.
I wanted to post some identifying photos to show a few of the sumac plants we discussed. I went to the USDA-ARCS Plants Database to make sure my images were accurate. Unfortunately there was no photo for the Prairie flame sumac Steve mentioned… maybe he’ll be able to add one.
Rhus trilobata, three lobed leaves
Poison Sumac has large alternate leaves with 9-13 entire leaflets
Staghorn sumac has 11 to 27 leaflets with serrate margins
