Title: Vines for a cliff in backyard
Answered by: Nan Hampton
QUESTION:
I have a large (25 ft) cliff in my backyard. Its too large to use a retaining wall and occasionally some of the caliche slides down. I'm planning on planting vines at the top and letting them drape over the edge and cascade downward. Hopefully the greenery will help with erosion. I'm thinking of Carolina jessamine and coral honeysuckle. Both evergreen and aggressive growers. What do you think and do you have other ideas?ANSWER:
Gelsemium sempervirens (Carolina jessamine) and Lonicera sempervirens (Coral honeysuckle) are good choices, although they are going to do their bests to try and climb up something. You might have to continually encourage them to trail down the cliff. Here are some suggestions for vines that are a bit better at trailing. They are all deciduous, however:
Parthenocissus quinquefolia (Virginia creeper) will happily trail down the cliff.
Campsis radicans (Trumpet creeper) will also be happy trailing down the cliff. It can be an agressive plant and you may need to keep it in check.
Merremia dissecta (Noyau vine) climbs by twining but will also trail down retaining walls. Here is more information and photos.
