This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring. Position: full sun; Soil: well-drained, fertile soil; Rate of growth: average; Flowering period: July to October; Hardiness: hardy (borderline) This new hyssop is dependably hardy to -5C, and it produces its fattened spikes of deep violet-blue flowers over a long period from midsummer. These not only look great, but they will also help attract lots of beneficial insects, so it’s perfect for a wildlife-friendly garden, while the rich green foliage, which releases its licorice-like aroma when gently bruised, makes it valuable for sensory gardens; Garden care: Don’t 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.
