Hiya,
I am looking for a plant which is a bit resistant to herbicides which could be used as a hedge. My mothers property has some highly unpleasant, drug cooking and doing neighbors to one side, she has a large fence which she had planted climbing roses all over but is currently heartbroken as they have all been killed by said neighbors via herbicides. She is not in the financial position to move sadly (and her property is lovely) so I suggested a hedge to help screen her out further, I know some plants are more sturdy against poisons, we would plant them a bit away from the fence line so they wouldn't be as vulnerable as the roses were but still need to be tough. We live on the west coast of New Zealand and her property gets very cold and wet over winter so it has to be something that can endure that.
Any suggestions?
