Q.How long does the skunk cabbage plant have green leaves. I’m thinking of entering some plants in a flower show
We plan to dig up some plants that live nearby in a wet shady spot and would like to enter them as part of a garden club display in the Newport (RI) Flower Show, which is in late June. The plants are quite small now – about 6″-8″. This is the kind of skunk cabbage that has unrolls a dark purple swirl.

The flower emerges in early spring, followed by the leaves. I couldn't find a source that said how long the leaves stayed green, but I think it would probably make it to your plant show.
Be aware it has medium poison attributes.
