Why It’s Called Wingstem

Two months before it blooms we can identify this plant even though it has no flowers.  Look at its stem!

Wingstem (Verbesina alternifolia) is already five feet tall and on its way to eight.  It will look like this in August.  Meanwhile the stem gives away its name.

The “wings” are petiole extensions that run the length of the stem.  The newest wings at the top of the plant are straight with a dark margin. The older part of the stem has long white hairs in the margins. Sometimes the wings are wavy.

To me the wings look like flanges.  “Flange-stem?”

Say that three times quickly and you’ll know why it’s called wingstem!
