Lavender Grosso Description
With one of the strongest fragrance among lavenders, Grosso is a popular French hybrid with gray-green evergreen leaves and fragrant, dark blue spikes that are nice and long - perfect for cutting, and for sachets and lavender wands. Flower spikes are larger and more plump than other lavenders, and rise well above the foliage mound. Grosso grows up to 36" tall x 36" wide and makes an aromatic, low growing, hedge plant or border plant. Known for high disease resistance, and recommended for the best dried flower bundles.
Lavender is heat, drought and wind tolerant. It needs full sun, and excellent sharp drainage. Shear faded blooms after flowering for a dense shape, and to promote reblooming.

Ideas and How-to's
Recommended for You:
Soil: Grow in average, dry to medium, well-drained, alkaline soil (pH should be 6.5 or higher). Prefers a light, sandy soil with somewhat low fertility.
Light: Full sun
Water: Dry to medium -- Root rot commonly attacks plants grown in poorly drained soils. High summer humidity in southern growing zones is not appreciated. To combat high humidity, consider using rock instead of organic mulch.
Spacing: 18 - 24 inches
Fertilizing: Feed with a light application of general purpose, or time release fertilizer before new growth begins in spring.
Winterizing: Plants may not survive in winter if soils are not well-drained and/or if temperatures dip below zero degrees without protective snow cover. Prefers southwestern exposure and protection from winter wind.
Maintenance & Pruning: Remove faded flowers to promote continued bloom. Prune once or twice a year to keep plant shapely. Prune option #1: in the spring after the lavender wakes up. Wait until the lavender has signs of new growth (do not worry if it takes a while to wake up). Prune option #2: in the fall around early October. The rule of thumb in pruning is 1/3 of the plant or about 2 inches above the wood. If you prune into the wood you run the risk of the plant not coming back.
