From Oak Park Public Library:

Plant Swaps are for everyone of all ages! This event encourages plant lovers to come together and trade pest- free plants of all kinds, which can include: Houseplants, potted plants, cuttings, seedlings, starters, succulents, air plants, wildflowers, annual or perennial, etc. No money is exchanged and it is a great way for beginners and expert gardeners to clean out or add variety to their collections. Drop in any time between 1pm - 3pm to give some plants and get some plants.
