Hi, I would be grateful for some help on deciding which berberis to buy. I live on a corner plot and want to plant a hedge around it. I think I've decided on berberis because it's prickly but there are so many varieties. I only want it about 1 meter high. I've read that it's quite hardy and grows in most soils. Also ive never purchased online before and I'm a little worried because I'll be spending a lot of money. Any advice would be appreciated.
