Veronica Sunny Border Blue (Spike Speedwell)

Highly popular, Veronica ‘Sunny Border Blue’ (Spike Speedwell) is a bushy, upright, clump-forming perennial producing dense, slender spikes of star-shaped, vivid violet-blue flowers from midsummer to fall. Attractive to butterflies, the flowers open from the base upward and sway above the luxurious foliage mound of lance-shaped, dark green, crinkly leaves. Prized by gardeners since its introduction in 1946, it deserves a place in every garden.
