I have a drop into my garden from a hard standing of .5m deep by 2.5m long, a wooden picket fence has been their for the past 20+ years and is now beyond repair. I was thinking of planting something evergreen that l could train along horizontal poles, must be very narrow, slowish growing and wildlife friendly, sun morning and evening in a dry, light neutral soil, open to the elements so must be 'hardy' and no more than about 2m tall. Can anyone help?
