Water Saving Tip:

Change spray sprinklers to low-flow bubbler or drip systems. Shrubs and trees are ideal candidates for this type of irrigation because the water is applied directly to the root zones.

  • Description

  • Notes

Grosso has the the darkest blue flower spikes of the French Lavenders. A heavy bloomer, the flowers have a strong lavender fragrance, and coupled with their long stems, they are excellent for arrangements or making lavender wands. Also excellent dried. It is very drought tolerant and is a great plant to create that Mediterranean effect. 30 inches tall by 24 to 30 inches wide.
Lavenders can resent pruning, so use a gentle hand. If pruning is necessary, only prune back 1/3 of new growth. When more growth is evident, prune back to just above new growth. Grow in full sun in well drained soil. Deer and rabbit resistant.
