The Piedmont Master Gardeners will hold their 20th Spring Plant Sale from 10 a.m. to 2 p.m. Saturday, May 6, at Albemarle Square Shopping Center in Charlottesville. The sale will offer thousands of annuals, perennials, vegetables, fruit-bearing plants, herbs and houseplants, including a large assortment of native plants. Among new offerings this year will be “Habitat in a Box,” a native plant combination that attracts pollinators and provides habitat throughout the growing season. There will be versions for sunny locations and for shade. In addition, shoppers can purchase garden implements, yard ornaments and other “Green Elephants,” and can drop off their tools for sharpening. The sale will happen rain or shine and will feature a Help Desk for answering gardening questions and educational displays on a variety of topics. All proceeds support the many free and low-cost programs the Piedmont Master Gardeners offer to the community. Credit cards, checks and cash will all be accepted.
