Veronica spicata subsp. incana 'Pure Silver' (Silver Speedwell)

Silver Speedwell 'Pure Silver', Spiked Speedwell 'Pure Silver'


Grown for both its foliage and flowers, Veronica spicata subsp. incana 'Pure Silver' (Silver Speedwell) is a compact perennial forming a low mound of narrow, toothed, lance-shaped, silver-gray leaves. The 3 in. long leaves (7 cm) are covered with many long white hairs, giving them an overall silver appearance. From mid to late summer, small blue flowers are borne in 3-6 in. long (7-15 cm) terminal racemes and persist for about 4 weeks. 'Pure Silver' is a popular edging plant that also provides good foliage contrast. It performs poorly in high heat and high rainfall areas because its hairy leaves trap moisture, resulting in foliar disease.

  • Grows in bushy, upright clumps, up to 12-24 in. tall (30-60 cm) and 9-12 in. wide (22-30 cm).
  • Performs best in full sun, in average, medium moisture, well-drained soils. Tolerates light shade. Thrives with consistent moisture but with sharp soil drainage. Water plants at the base in an effort to avoid wetting the foliage.
  • Perfect choice for borders, cottage gardens, rock gardens or containers. Excellent fresh cut flower.
  • No serious insect or disease problems.
  • Remove spent flowers to promote additional blooms. Shear back the foliage if it becomes worn-looking after flowering.
  • Clumps may be easily divided in spring or early autumn.
