Director of Horticulture at the Native Plant Trust in Framingham, Massachusetts, and former Curator of Native Flora at the Brooklyn Botanic Garden, Uli Lorimer has written a new book, The Northeast Native Plant Primer, 235 Plants for an Earth-Friendly Garden. An outstanding introduction to gardening with native plants, it is especially relevant for residents of the northeastern United States but has much to offer to gardeners in other regions of the country as well.
