Ivy
Hedera helix
Another climber, this one evergreen and self supporting, and so even better than honeysuckle for screening unattractive fences and buildings. Ivy produces its pale yellow flowers in winter, food for the few winter-flying insects, and its berries ripen in spring when they are an important food for blackbirds and thrushes.
A good wildlife plant, it may need to be controlled in woodland. Ivy is not a parasite of trees, but its sheer weight may make a tree more liable to wind blow. Ivy grows easily from berries and small rooted branches may also be transplanted.
