Lavender Grosso: The Aromatic Fat Spike Lavender for Stunning Gardens
Lavender Grosso, also known as Fat Spike Lavender, is a fast-growing perennial herb that captivates with its striking dark purple flower spikes and intense fragrance. This hybrid variety, scientifically named Lavandula x intermedia ‘Grosso’, combines the best traits of its parent species, offering gardeners a resilient and adaptable plant that matures quickly and provides long-lasting beauty. Recognized for its silvery-gray foliage and densely packed purple blooms atop elongated stems, Grosso Lavender stands out as a premier choice for both ornamental and aromatic purposes.
As one of the most fragrant hardy lavenders available, Grosso Lavender excels in multiple landscape applications. Its deer-resistant nature and ability to thrive in dry conditions make it an excellent choice for low-maintenance gardens. The plant’s robust growth habit and ample flower production render it ideal for creating fragrant hedges, mass plantings, or as a standout specimen in herb and rock gardens. Moreover, its flowers are perfect for drying, preserving, and using in sachets, perfumes, and aromatherapy, offering a versatile addition to any garden or home.
Lavender Grosso typically reaches a mature height of 24-30 inches with a spread of 18-24 inches, forming a dense, multi-stemmed evergreen shrub with a mounded form. It blooms prolifically from mid to late summer, producing an abundance of aromatic flower spikes that are longer and thicker than those of many other lavender varieties. This lavender variety not only attracts butterflies but also resists rabbits and deer, making it a valuable addition to pollinator-friendly gardens.
Growing Success Tips:
- Plant in full sun and well-draining, slightly alkaline soil for optimal growth
- Water sparingly once established to prevent root rot
- Prune annually after flowering to maintain shape and encourage reblooming
- Space plants 18-24 inches apart to ensure good air circulation
Lavender Grosso offers gardeners a low-maintenance, high-reward plant that combines beauty, fragrance, and versatility. Its ability to thrive in both hot and cold climates makes it an excellent choice for a wide range of gardeners. For best results, shear the plant about halfway down after flowering to promote bushiness and encourage a second bloom.
