This week's Puddledock Park Party theme is Perennial Swap. It's a perfect opportunity for you to dig up those perennials that you no longer love or have prospered a bit too well under the care of your green thumb, and swap them with other folks.

Of course, the Puddledock Park Party is a social event. So even if you don't swap perennials, come swap stories and make community with friends and neighbors. Feel free to bring your own seating, snacks and drinks, and bug spray.

Puddledock Park Party starts at 5pm and runs to ever-earlier dusk.
