You can plant a mixed hedge of leylandii without a problem. Efford Horticultural Research Station tried out lots of different cultivars (varieties) of Leylandii about 30 years ago and planted mixed hedges. These were all very successful. All leylandii is fine if it is looked after and trimmed once or twice a year. There is good advice on how to trim your leylandii hedges at www.leylandii.com and www.evergreenhedging.co.uk . It is true that the green leylandii grow faster than the golden leylandii, so if you want a tall hedge, and you plant small plants, the green will get to the height quicker than the gold. This is not a problem in the long run as they will just merge in together. I hope this is not too late to help.
