Lavandula × intermedia 'Grosso'
Grown across Provence, a billowing mound of dark-blue tapering flowers, held on long stems, splaying outwards in late summer and autumn above a close mound of foliage that can be shaped for winter interest.
- Position: full sun
- Soil: moderately fertile, well-drained soil
- Rate of growth: vigorous
- Flowering period: July to August
- Hardiness: fully hardy
This vigorous English lavender produces masses of long, slender stems, that are topped with clusters of vivid violet flowers between July and August, above mounds grey-green leaves. It makes a gorgeous, flowering, informal hedge, especially along a path, where its fabulous fragrance can best be appreciated. It works well in a Mediterranean garden, or clipped into a formal sphere for a contemporary look. The highly scented flower-spikes are also a magnet for bees and other nectar-loving insects.
- Garden care: Cut back the stalks after the flowers have faded to retain a compact shape. Carefully trim back in April, taking care not to cut into old wood.
