Lindsay Winger is organizing Brock's annual Perennial Exchange.

Thinking green has a new meaning at Brock this month as green thumbs campus-wide participate in a plant swap.

The annual Perennial Exchange will be Wednesday, May 25. Brock faculty, staff and students are encouraged to bring in flowers, herbs, evergreens, vines, ornamental grasses and other foliage to exchange for new plants.

The annual event is part of Brock’s ongoing sustainability efforts, said Lindsay Winger, Student Leadership and Engagement co-ordinator. Organizers are hoping more people get involved this year.

“It started as a niche group of staff who like to garden, but we’re trying to get more interest,” she said. “We’re trying to encourage students as well.”

Growers can bring up to five perennials (in pots, clearly labeled with a name and sun/shade preference) to the front of the Schmon Tower from 8:15 to 9:30 a.m. You will receive a voucher for each plant you leave.

From noon to 12:30 p.m., you can return and redeem the coupons by picking up new plants. From 12:30 to 1 p.m., everyone can come purchase leftover plants, which will cost between $1 and $5.

Organizers will accept “anything but invasive plants and weeds,” Winger said. That includes ferns, bulbs, shrubs and pond plants.

Rain barrels will also be sold at the event.
