Tough and hardy, snow-in-summer is a vigorous, mat-forming perennial native to Italy. Its low-growing, fine, wooly, silver-gray leaves often persist through winter. In late spring to early summer, it blooms showily with five-petalled, star-like white flowers on stalks, covering the plant so densely that it resembles a mound of snow. This selection, ‘Columnae,’ lifts the flowers slightly higher than the parent species. The flowers draw many pollinators.
Give ‘Columnae’ full sun and average to poor soil with sharp drainage. Like other silver-leaved plants of the Mediterranean, it is quite drought tolerant once established. Use it in sunny rock gardens, to fill pockets in stone walls, or as a sun-loving groundcover for contrasts of texture and color in beds and borders.
Perennials are plants that complete their lifecycle in three or more years.
We carefully select perennial varieties that will do well in our Western New York Gardens. All our perennials are hardy to Zone 6 for those of us nearer to the lake, and most are hardy to Zone 5.
