Come to Meadowscaping for Biodiversity’s native plant sale and planting workshop on Saturday, June 8 from 10am-2:30pm at the First Parish Church (50 Church St., Waltham). Learn that perennials save time and money — they come up every year, require less water and maintenance, soak up excess stormwater, sequester carbon and serve as food and energy for endangered bees and butterflies. ¬†Find out how important native perennials are to the future of our planet and our food supply. For more information, contact Barbara Passero at 781-209-0052, or Jean Devine at 617-947-6256.
