What sets Grosso apart is its exceptional fragrance intensity and versatility, making it the go-to choice for perfume production, sachets, and culinary creations. The long, graceful stems crowned with bold violet-blue spikes create stunning cut flower arrangements and serve as natural pollinator magnets. This drought-tolerant beauty thrives as a fragrant hedge or in mass plantings, offering evergreen structure year-round while remaining deer resistant and incredibly low-maintenance once established.
Grosso excels in perfume making and sachet creation thanks to its intensely concentrated oils, while culinary enthusiasts incorporate its flowers and leaves into teas, baked goods, and savory dishes. The long stems make exceptional cut flowers for fresh or dried arrangements, and the plant serves beautifully as a fragrant hedge, border planting, or container specimen. Essential oil production and craft projects like potpourri showcase its enduring fragrance.
Plant transplants in spring once soil temperature reaches at least 60°F and the threat of frost has passed. Mix compost or organic matter into the planting area and space plants 36 inches apart for optimal airflow and mature spread.
Harvest stems when about half of the flowers are open, particularly if planning to dry them for crafts or culinary use. Cut no more than one-third of the plant at any time to maintain plant health. Morning harvest captures the most concentrated oils, making it the ideal time for collecting lavender flowers.
Prune annually after flowering by cutting back to half the plant's size to maintain shape and vigor. In warmer climates, prune in the fall, while in colder zones, wait until spring as new growth appears and prune only the new growth on established plants.
