Description
Lavandula x intermedia ‘Grosso’—often called Fat Spike Lavender—is a powerhouse hybrid between English (angustifolia) and Portuguese (latifolia) lavender. It’s prized for its exceptionally long, deep violet flower spikes, intense fragrance, and robust growth habit.
Here’s what makes ‘Grosso’ a standout in your landscape palette:
- Size & Form: Grows into a dense, rounded shrub about 75–90 cm tall and 60–75 cm wide.
- Blooms: Produces 6-inch (15 cm) flower spikes from mid to late summer, ideal for drying, distilling, or dramatic garden displays.
- Foliage: Silvery-green and aromatic, offering year-round texture.
- Fragrance: One of the strongest among lavenders—perfect for sachets, oils, and potpourri.
- Conditions: Thrives in full sun, alkaline, well-drained soil, and tolerates drought, frost, and even snow.
- Uses: Excellent for mass planting, herb gardens, rockeries, or as a specimen shrub. Also, a magnet for bees and butterflies.
