Calluna vulgaris ‘Sister Anne’ In all the time I’ve been designing gardens, I have never had anyone tell me, “please, no heathers!”. Thank goodness, because heathers are my secret weapon for extending any season’s interest. By the end of summer many perennials have stopped blooming, but the winter bloomers and fall colors haven’t started in earnest to continue the show. If you’ve got some autumn bare spots in your garden, how about tucking a few heathers into the foreground? They even work in seaside or deer gardens.
