I have two old and brown round box hedge shrubs either side of two steps leading from the patio to a lawn area. Can't stand them as they always look half dead. Looks like rust. Thinking of replacing them. I like the idea of something evergreen and leafy but compact. Other plants near them are summer perennials or roses. I have been looking at hebe shrubs or some kind of mini conifers. I like the idea of them looking 'matching' either side of the steps. Needs to be hardy.......and low maintenance!Any ideas greatly recieved.
