Mother of all sales

Plant sale season is in full bloom and one of the big ones is this weekend at the Minnesota State Fair Grandstand. The Friends School Plant Sale features more than 2,000 different kinds of plants across 2.5 acres, including herbs, perennials, vegetables, grasses, climbing plants, annuals, shrubs and trees and those hard-to-find rare specimens. At the Garden Fair, browse exhibits by local gardening organizations and shop for garden ornaments, trellises, planters and supplies. Workshops and demonstrations on Saturday cover everything from gardening for bees to worm composting.

Do your homework before hitting the sale by viewing the catalog and creating an online shopping list on the website. Wristbands will be distributed before the sale opens each day — so come early. Hours: 9 a.m. to 8 p.m. Fri., 10 a.m. to 6 p.m. Sat., 10 a.m. to 2 p.m. Sun. The last day — Mother's Day — plants are one-third off. Free admission and parking.
