I have just taken down an old pyramid cedar hedge at the front of my property on the advice of 2 arborists who advised that one of the main problems was too much shade from surrounding trees. I would like to replace it with an informal hedge entirely of rhododendrons - total of about 40'. I live on a very busy street and the rhodos would get part sun or dappled shade depending on their position. Does anyone have any advice on using rhodos as a hedge? Preferred height at maturity is 5-6' and I love vibrant colours, such as red, purple or hot pink. I am thinking one colour and one variety all the way across is the way to go - any comments on this? I found a variety called "Nova Zembla" which "grows in difficult areas" and sounds very hardy. Is this easy to acquire in BC? I am not much of a gardener and am not looking for complicated plantings or high maintenance plants.
