Agastache aposBlue Fortuneapos Mexican giant hyssop

Position full sun Soil well drained, fertile soil Rate of growth average Flowering period July to October Hardiness hardy borderline 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 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. Garden care Donapost cut back the faded flower stems in until early spring, as they provide interest in the winter months. Lift and divide congested colonies in spring.
