From early spring to early summer rich ocean-blue flowers form a carpet bloom. Well adapted to hot dry conditions but also cool climates to USDA Zone 6a. Excellent for growing in garden beds and truly spectacular in pots, planters and other containers where its foliage adds intriguing texture and form.

Can also be grown in well-lit indoor spaces. A fine evergreen addition to herb gardens, fragrance gardens, Asian gardens, cottage gardens, cut flower gardens, blue color theme gardens. kitchen gardens, and the Xeriscape (low water needs).
