Family

Scrophulariaceae

Botanical Name

VERONICA spicata ssp. incana

Plant Common Name

Silver Speedwell

General Description

Forming handsome carpets of fuzzy silvery semi-evergreen leaves, this herbaceous perennial is native to the steppes of Russia. In summer, it bears plumy spikes of purple-blue flowers in candelabra-like clusters. They attract bees and butterflies. Silver speedwell has been crossed with spike speedwell to produce several silver-leaved cultivars, including the pink-flowered 'Minuet' and violet-blue-flowered 'Sarabande.'

This beautiful perennial does best in full sun and well-drained soil. Avoid over-watering. Silver speedwell can be used in the mixed border, rock garden or as a small-scale ground cover. It looks beautiful when mixed with yellow- and pink-flowered perennials such as Dianthus and potentilla.
