Plant for four seasons of interest by including native trees and shrubs with dramatic color in leaves, fruit, or late-blooming flowers. Even the long months of winter can be brightened by native species that have evergreen leaves, interesting bark, striking silhouettes, or persistent fruit. Add interest to the view from your kitchen window, encourage winter birds and wildlife, and improve your home’s curb appeal in the “off season”. Recommendations for planting design and maintenance included. Laura Eisener teaches this class, co-sponsored by the New England Wild Flower Society and the Cambridge Center for Adult Education, at the Cambridge Center’s headquarters, 42 Brattle Street in Cambridge. $22 for members of either organization, $26 for nonmembers.
