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 attractive to butterflies and bees. They are short-lived though, and may need replacing every few years, especially after a cold or wet winter. 'Blue Fortune' has loose spires of lilac-blue flowers from June 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.


  • Garden care:
    Plant in a well-prepared bed, lightly conditioned with well-rotted compost or manure. Keep cutting the old stems out to encourage repeat flowers through the summer. Once the flowering period is over, resist the temptation to cut back the faded flower-stems until early spring, as they provide interest in the winter months. Once established, lift and divide congested clumps in spring. Protect roots during the winter with a thick layer of organic mulch around the root zone.
