Free Plant Swap for Union County Gardeners, June 6

Union County, NJ — On Thursday evening June 6 from 5:30 p.m. to 8:30 p.m., all gardeners are invited to the “Native Plant Swap and Shop” event at the Union County Demonstration Garden, where they can trade an invasive plant from their yard for a colorful native plant, free of charge. Attendees can come at any time during the event and stay for as long as they like.

Pink, lavender, white, red, blue and purple flowering native plants are available for swap including swamp milkweed, wild bergamot, dense blazing star, and hummingbird-friendly foxglove beardtongue and cardinal flower.

Additional native plants are also available for sale at the event, and attendees can tour the Demonstration Garden

“The Native Plant Swap and Shop makes it easy to find the best native plants for your yard and connect with expert, reliable guidance on gardening with native species,” said Freeholder Chair Bette Jane Kowalski.

Gardening with native plants is an effective way to save time, cut yard care costs, and contribute to the health of the local ecosystem.

Native species thrive naturally their home environment. They enable gardeners to avoid using potentially harmful herbicides and pesticides. Native plants can help reduce ponding and runoff, and they also support local populations of butterflies, birds, and other beneficial pollinators.

Non-native plants can be difficult to control and can easily overrun other varieties. Invasive non-natives common to the Union County area include multiflora rose, Japanese barberry, English ivy and garlic mustard.

Chinese silvergrass, purple loosestrife, winged burning bush, and butterfly bush are other common non-natives. Union County’s free, downloadable Plant This, Not That guide includes more information on identifying invasive species and gardening with native plants. Additional information is also available through the Rutgers University native plant program

The Demonstration Garden is located on the grounds of Union County’s Trailside Nature and Science Center, at 452 New Providence Road in Mountainside. Ample free parking is available on site.

The Native Plant Swap and Shop event is hosted by the Union County Department of Parks and Recreation in partnership with the Master Gardeners of Union County. The all-volunteer Master Gardeners tend the Demonstration Garden and provide many other acts of community service in Union County. 

Admission to the event is free but pre-registration is requested by emailing
