Gardener Jodie Gilson will be giving a presentation at the Groton Public Library from 7 to 8:30 p.m. on Feb. 27. Participants will learn about garden design, plant sourcing, and sharing their garden. They will also take home a 4-inch pot planted with their choice of seed. The free event is open to adults and children 8 and older. Participants may arrive a few minutes early to look at the library’s seed lending library.
