Drop by Calloway’s Nursery at 2651 Hulen St. this Saturday (April 3) and trade plants with other gardeners at the nursery’s Perennial Swap. You can bring extras from your own garden and pick up surplus from others, all for free. The swap is from 9-11 a.m.

At 10:15 a.m., the nursery will also hold a Perennials Clinic to teach you about choosing, caring for and selecting perennials.

These events are also taking place at Calloway’s Nursery at 1000 Preston Rd. in Plano.
