With one of the strongest fragrance among Lavenders, Lavandula x intermedia 'Grosso' is a vigorous grower which produces exceptionally large and rich, deep violet flower spikes up to 6 in. long (15 cm), hence its common name of 'Fat Lavender'! A favorite variety for wands or sachets as the flowers retain their fragrance and color when dried.
- Evergreen in warm winter climates, it typically grows 24-36 in. tall (60-90 cm) in a tight and tidy mound of silver-green foliage that bears the most attractive foliage colors of all the lavenders.
- Thrives in full sun and blooms from mid to late summer. It performs best in dry to medium, poor, light, sandy, alkaline, well-drained soils. Excellent drainage and air circulation are essential, specifically in hot, humid climates.
- Drought, deer, rabbit and dry soil tolerant and a real magnet for bees and butterflies!
- It is a great candidate for herb gardens, borders or rock gardens and provides a stunning effect in mass plantings. Individual plants also make good showy specimens in the garden, but leave some room around the plants to enable the flower stems to fully display their natural, glorious curves.
- Remove faded flowers to encourage further blooms. Prune to shape in spring after the new leaves appear.
Lavandin (Lavandula x Intermedia) is a popular hybrid lavender combining the cold-hardiness of the English lavender (Lavandula angustifolia) and the heat tolerance of the Portuguese lavender (Lavandula latifolia), therefore providing an answer to the gardeners' worldwide quest for a Provencal atmosphere in their gardens. These Lavender plants are usually taller than the English Lavender and grow in shrubby compact mounds up to 36 in. tall (90 cm). They are adorned with long, loose spikes of highly fragrant flowers, ranging from dark violet to white from early to late summer. The cultivars of this group of Lavenders tend to be more tolerant of acidic conditions.
