Long, slender spikes of palest blue flowers, almost white but with an unmistakable hint of blue. Flowers are produced freely in early summer over green mats of foliage. Spreading, but not too widely. It will die back for winter but is very hardy and will expand slowly year on year.
An easily grown plant for any sunny, well-drained site. About 12cm high (5") spreading to perhaps 35cm (14") wide in time.
