Organic Grosso Fat Spike Lavender

Organic Grosso Fat Spike Lavender is a certified organic lavandin selected for substantial deep-violet flower spikes, long stems, and silver-green foliage. Often called Grosso lavender, it is especially useful for dried bundles, lavender wands, sachets, and bold mass plantings because the stems hold their shape and the flowers retain noticeable color after drying.

Grosso is a perennial listed for USDA Zones 5–9. Give it full sun, open air movement, and dry-to-moderate soil with rapid drainage. It performs well in warm summer conditions once established, but wet crowns can cause decline. Verify local winter conditions with the USDA Growing Zone lookup. No pollinizer companion or chill-hour total is required.

Transplant at the existing root-ball level and water thoroughly to settle soil. During establishment, check the actual root zone and irrigate when it begins to dry. Mature plants generally need less frequent watering, adjusted for heat, wind, soil texture, and container exposure. Avoid rich, nitrogen-heavy conditions that create soft stems. Space plants so the broad mound and tall flower wands have room to develop.

Cut spikes when buds are colored and the first lower florets begin opening for drying; harvest later for fresh display and garden color. Tie only small bundles so inner stems dry completely. After bloom, remove spent wands and lightly trim green growth without cutting deeply into leafless wood. Watch for spittlebugs, mites, leaf symptoms, and root stress. Review the small-plant transplant guide for establishment and the herb harvest and drying guide for preservation.
