The latest thing in architecture is green buildings—covering walls and roofs with a carpet of plants to prevent heat, absorb rain and provide a home for wildlife. Many such buildings need complex systems for holding and irrigating the soil.
Ivy is a group of evergreen climbing plants, whose power to live is hard to beat. Firstly, it can live in almost any surroundings, whether in shade or full sun.It grows well in both dry and damp soil. Moreover, it doesn't need supports as it grows aerial roots that can be attached to most things. For these reasons, ivy can be widely grown to beautify an ugly wall or a fence.It is a heaven for bees and butterflies in summer and its berries are a valuable food source for birds in winter.
However, there are some concerns about growing ivy. Ivy has a reputation for damaging buildings, but according to the UK's Royal Horticultural Society, this doesn't usually happen unless the walls already have cracks.But Blanusa at the University of Reading, UK, who has examined the effects of plant climbers, finds that ivy raises humidity next to the wall by only a small amount.
