Veronica 'Sunny Border Blue' (Spike Speedwell)

Spike Speedwell 'Sunny Border Blue', Veronica spicata 'Sunny Border Blue'


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.

  • 1993 Perennial Plant of the Year
  • Grows in bushy, upright clumps, up to 18-24 in. high (45-60 cm) and 15-20 in. wide (37-50 cm).
  • Performs best in full sun, in average, medium moisture, well-drained soils. Tolerates light shade. Best performance occurs with consistent moisture combined with sharp soil drainage.
  • Perfect choice for borders, cottage gardens, coastal gardens, rock gardens, or containers. Good edging plant too. Exceptional as cut flowers. Best when planted in groups.
  • Easy to grow, Speedwell requires very low care and is fairly pest and disease-free (some susceptibility to mildew). It is attractive to butterflies, but resistant to rabbit and deer.
  • Remove spent flowers to promote additional blooms. Shear back the foliage if it becomes worn-looking after flowering.
  • Propagation is easily achieved by division or vegetative cuttings.
