I need a pretty (hardy) ivy to be planted along a rail fence for year round privacy. Any suggestions?
Boston ivy, Clematis virginiana, climbing hydrangea, and trumpet or coral honeysuckle vine are worth considering. For a rapid effect, the annual cardinal climber, Ipomoea multifida will fill the spot quickly while the perennials are getting a start. Many perennials don't grow upward much their first season; the time is spent establishing roots instead. The perennial vines mentioned in the first sentence are hardy to zone 4, I believe. If you are in the South, additional options are Carolina jessamine, crossvine, Kentucky wisteria and passionflower. Some of these get quite large and need a very sturdy support. The amount of sun that the area gets is an important factor when choosing your vine.
