Hi,
This plant started growing in a perennial bed but not sure what it is. It is about 2 feet tall and almost 3 feet wide. There are about 14 little leaflets on each stem and the leaves come out in groups of stems with leaflets. The stem is reddish brown. The leaves are kind of chartreuse with a reddish cast on the new leaves. The leaflets have serrated edges and the veins are very prominent. This is one stem from the shrub for the sample. There is now another one of these plants starting to grow about 2 feet from this plant. This plant does not flower and dies back in the winter. Can you tell me what this plant is? Thanks

Hello,
To help me key it out, would you let me know whether the branches alternate off the stem, or opposite each other on the stem? Do the branches all arise from the base, or do they branch off of larger stems?
Thank you,

The branches alternate off a main stem. There is one main stem with branches alternating from it. So the branches do not all arise from the base - they branch off a larger stem. This stem comes up from the ground and then the branches alternate off this main stem. The stem is not very thick - maybe just 1 -1 1/2 inches thick.

Thank you for the additional info. Based on the photos and info, this is likely Smooth Sumac (Rhus glabra), a native shrub. Below are several fact sheets on this plant to help you confirm. You are also welcome to bring in a sample to the Jeffco Plant Diagnostic Clinic for definitive ID ($7 for Jeffco residents).
