English ivy (Hedera helix) is one of the most commonly used ivy plants for growing up walls and the sides of houses. English ivy is an evergreen creeping vine that can climb walls up to 50 feet high.

They found ivy acted as a thermal blanket, warming up walls by 15 per cent in cold weather and cooling them in hot weather by an average 36 per cent.
