A real treat for lovers of mint, aniseed and liquorice! Hyssops are great for adding vertical accents to a border, with whorls of long-lasting, tiny flowers arranged like a bottlebrush and pointed, aromatic fresh green leaves that are a magnet for butterflies and bees. 'Morello' has loose spires of deep-pink flowers from July to October and peppermint-scented leaves. This upright, bushy perennial is perfect for the middle of a sheltered, sunny border. Try it as part of a Mediterranean scheme, with grey-leaved plants, or among ornamental grasses.
