*Optional birding hike: Meet the presenter, Eric Butler, at 8 am in the WCMGA Education Garden at PCC Rock Creek (just south of Building 9). Eric will lead a one-hour guided birding hike starting in the Ed Garden and then continuing to the natural area at the north end of the PCC Rock Creek campus (weather permitting).

Cornell Farm Houseplant Swap at Bethany Village

Thursday, May 25, 3-6 pm, Bethany Village Center, 15160 NW Laidlaw

At Cornell Farm, we believe in the power of plants to connect people. And that’s why we’re excited to take one of our famous Houseplant Swaps on the road! Any and all indoor plants are welcome, from common finds to coveted collector varieties, but please keep in mind that this is an event about exchanging plants and knowledge, not cash.

All plants should be labeled, healthy, and pest-free! In general, cuttings should be rooted, but if you have fresh cuttings to share from easy-to-root plants, these could be acceptable offerings for the free table (more info below). Be sure to bring cuttings in containers that you don’t care to get back—recycled mason jars, plastic cups, and baggies work great!

Learn more on the Facebook event page here. No sales. This event aims to celebrate the spirit of generosity between plant enthusiasts. Please don’t offer to buy or sell. We encourage trading and giving! What if I don’t have anything to trade? Bring your questions! We all have to start somewhere, and you might just go home with a plant or cutting in addition to your new knowledge.
