Effective landscape design includes creative use of vertical space, and vines should be considered from the outset. While touring the Leventritt Garden of Shrubs and Vines, horticulturist Jen Kettell introduces an array of woody vines. She explains their various growth habits and attachment mechanisms which determine how they are best used in the garden. Focusing on floral, foliar, and fruiting characteristics, she recommends vines for a variety of garden settings. The program, taking place Thursday, June 17 from 6 – 8 pm, is co-sponsored by The Arnold Arboretum and by The New England Wild Flower Society. Register on line at www.newfs.org ($20 for members of either sponsoring institution, $24 for nonmembers).
