Most people don't like them but they are good for a quick screen. They grow 3 foot a year or more and can be clipped to any height. They also come in green or gold.(its actually a hybrid genus,a cross between cupressus and chamaecyparis- xcupressocyparis)

I am a huge fan of leyland cypress, but I don't think they are fully hardy in central Ohio...I tried growing them in the Cincinnati area and they all died during our winter. They grew like weeds when I lived in south carolina though...great screen plants...I might try something a bit more reliably hardy for central OH though.

Thanks--am crossing the leyland cypress off of our list.
Thanks again for helping with our decision.
