Sunny Border Blue Speedwell has masses of beautiful spikes of royal blue flowers rising above the foliage from early summer to early fall, which are most effective when planted in groupings. The flowers are excellent for cutting. Its narrow leaves remain dark green in colour throughout the season.
Sunny Border Blue Speedwell is a dense herbaceous perennial with an upright spreading habit of growth. Its medium texture blends into the garden, but can always be balanced by a couple of finer or coarser plants for an effective composition.
