Veronica spicata 'Royal Candles' (Spike Speedwell)

Spike Speedwell 'Royal Candles', Veronica spicata 'Glory' PP18932


Regarded by many as the best upright form of Speedwell, Veronica spicata 'Royal Candles' (Spike Speedwell) is a bushy, upright, clump-forming perennial producing dense, slender spikes of star-shaped, deep blue-purple flowers from early to late summer. Attractive to butterflies, the flowers open from the base upward and sway above the bushy foliage mound of lance-shaped, deep green leaves. Unlike some other veronicas, the bottom foliage of this variety does not die out. This quality coupled with its compact habit makes it ideal for the front of the border, as an edging, or in containers where it will create a dramatic impact.

  • Grows in bushy, upright clumps, up to 15-18 in. high (37-45 cm) and 15 in. wide (37 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.
