Interesting herbaceous perennial with a neat, compact form and gray-white leaves that resemble thyme. Diminutive violet flowers form in mid-summer and continue through fall into winter. Difficult to establish and temperamental, requiring well-drained soil and full sun, but worth the effort. Consider planting in containers or dry rock gardens. Requires occasional supplemental water especially during prolonged dry spells. Hardy to perhaps 25F. Mexican provinces of Puebla and Oaxaca.
