Lavandula x intermedia 'Grosso' (Lavender)

Bold color, long stems, and exceptional harvest potential.

Lavandula x intermedia ‘Grosso’ is one of the most widely grown and trusted lavandins—and for good reason. Renowned for its deep, saturated violet blooms, this variety offers some of the richest color available among lavandins, paired with long, sturdy stems ideal for harvesting, drying, and crafting.

‘Grosso’ produces abundant flower spikes with dark violet-green calyces and vibrant violet corollas, creating dramatic contrast in the garden and striking results when dried. It is especially valued for fresh and dried arrangements, lavender wands, sachets, and large-scale harvests. In favorable conditions, this cultivar can bloom twice in a season, extending the harvest window and increasing yield.

Its tidy, compact growth habit makes it easy to manage despite its larger size, while its drought tolerance and deer resistance add to its reliability in diverse landscapes. This is a workhorse lavender—productive, resilient, and visually impressive—making it a top choice for commercial growers, crafters, and gardeners who want strong performance with minimal fuss.
