Ivy growing under our house stairs.
Hi Nick,
your vine is called Virginia creeper, Parthenocissus quinquefolia. Quinquefolia means 5-leaved – so not at all related to the three-leaved poison ivy. Harmless, sometimes weedy, but native. It is actually related to grapes, but not edible.
Sincerely,
Dr. Steven Hill, Botanist, SCNPS
