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.
