More than 16,000 curated selections of unusual perennials and annuals, native Ohio plants and heirloom and organic vegetables will be available at the Chadwick Arboretum and Learning Gardens' annual plant sale and auction May 11 and 12.

The fundraiser will take place at the northwest corner of Lane Avenue and Fred Taylor Drive, next to the Nationwide and Ohio Farm Bureau 4-H Center, 2201 Fred Taylor Drive. Free parking is available in the Gray lots at the Jerome Schottenstein Center across the street.

Auction items include unusual trees and shrubs donated from more than 25 nurseries and landscape businesses across the state.

Chadwick Arboretum horticulturists and representatives from Franklin County's master-gardener program will answer questions about edible and ornamental plants.

The plant sale will be open from 8 a.m. to 7 p.m. Friday, May 11, and from 8 a.m. to 3 p.m. Saturday, May 12.

Premium tree and shrub auctions are set for 4 p.m. May 11 and 10 a.m. May 12.

"We offer varieties that can't be found anywhere else, and new for this year is a focus on plants selected to support the effort to protect and preserve the monarch butterfly," said Trisha Clark, program manager for Chadwick Arboretum. "You'll find a wide variety of fairy-garden plants, such as mosses and creeping herbs, as well."

Proceeds from the event benefit the arboretum, Ohio State University student organizations and local vendors.

This year marks the 31st anniversary of the plant sale. It first was held in 1987 and coincides with National Public Gardens Day.
