English Ivy is rather delicate for this climate and will do well only against the south side of a wall, or on the ground where it may be readily protected in Winter. It is particularly effective against bricks. You may be able to find some variety of Ivy in the neighbourhood of your home, in some old yard or garden, some vine that has the characteristics of the English Ivy yet has become acclimatized and is hardy. Get cuttings of this and use them on your brick wall.
Do not use Boston Ivy (Ampelopsis Veitchi) in the country; it is a boulevardier among vines, and is at home only in the neighbourhood of asphalt and lamp-posts.
