Why We Love It:
Teucrium cossonii is one of those plants that quietly transforms a space. Its soft, silvery foliage forms a dense, flowing mat that looks perfectly at home spilling over stone walls or softening the edge of a pathway. The lavender-blue flowers add a subtle layer of color, but it’s really the texture and movement that make this plant stand out. Exceptionally drought tolerant and deer resistant, it’s a dependable choice for waterwise landscapes where structure and softness matter just as much as bloom.

Additional Info:
Native to the Balearic Islands in the Mediterranean region. Performs best in dry conditions with sharp drainage and minimal supplemental water once established. Deer resistant, highly heat tolerant, and excellent for gravel gardens, crevice plantings, and sunny slopes.
