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.
