Woodruff

This delicate-looking alpine forms low, spreading mats of fine, needle-like green foliage. In early to mid-summer, it produces an abundance of tiny, tubular, four-petalled flowers that are typically a soft, pale pink. The overall effect is a misty, ethereal cloud of colour that looks beautiful spilling over the edges of a stone trough or softening the lines of a rockery. It is native to mountainous regions and prefers a well-drained, gritty soil that does not dry out completely in the height of summer. In a UK garden, it is best placed somewhere where its subtle beauty can be appreciated up close. It is relatively easy to grow compared to some of the more temperamental high-alpines but still requires excellent drainage at the crown. It is a good companion for smaller bulbs and other mat-forming plants. The foliage has a pleasant fragrance when crushed, similar to its larger woodland relative, Sweet Woodruff. Although small, it is surprisingly tough.
