Great idea to grow Ivy on your terrace wall, Roarstor!
It is a valuable plant for wild life, bees, butterflies and many other insects feed on the flowers, and the berries (if you let it bloom) are a winter source of food for many species birds in the winter, besides providing nest opportunities.
I have a lot of Ivy growing in my garden, different types in different locations and conditions, all do well in full sun and even deep shade. The English Ivy, Hedera helix and its cultivars, the Irish Ivy, Hedera hibernica with larger foliage. Hedera canariensis probably would not be hardy in Norway..
Personally I find Hedera helix the most attractive especially the cultivar 'Saggitifolia'.
