Lavandula x intermedia 'Grosso' is a world-famous, sterile hybrid lavender prized for its exceptionally strong fragrance, long sturdy flower spikes, and abundant, deep violet-blue blooms. This vigorous Lavandin cultivar forms a dense, upright, mounding shrub of aromatic, gray-green to silvery-green foliage (leaves emerge green, aging to silvery-gray). From mid to late summer, it produces an impressive display of long, thick, densely packed flower spikes rising well above the foliage, covered in small, tubular, deep violet-blue flowers. The flowers are renowned for their intense, camphor-rich lavender fragrance, making 'Grosso' one of the most popular lavenders for commercial essential oil production, dried buds (culinary or sachets), and cut flowers. Highly attractive to bees, butterflies, and other pollinators, it also has excellent tolerance for heat, drought, deer, and poor, well-drained soils. It is an outstanding choice for low hedges, borders, mass plantings, slopes, and containers.

Q: What is 'Grosso' known for?
A: It is world-renowned for its exceptionally strong, camphor-rich lavender fragrance and is one of the most popular lavenders for commercial essential oil production, dried buds, sachets, and potpourri.

Q: How is it different from English lavender (L. angustifolia)?
A: 'Grosso' is a Lavandin (hybrid) with longer flower spikes, a stronger, more camphorous fragrance, higher oil yield, and a more vigorous growth habit. It is sterile, so it does not self-seed.

Q: When does it bloom?
A: It is a mid to late summer bloomer (typically later than English lavenders), producing its abundant flower spikes from mid-summer into early fall.

Q: How much sun does it need?
A: For the densest growth, best flower production, and strongest fragrance, plant in full sun (at least 6 hours of direct sunlight daily).

Q: Is it good for cut flowers?
A: Yes, its long, sturdy stems and densely packed flower spikes make it an outstanding choice for fresh-cut bouquets and dried flower arrangements.
