Veronica umbrosa 'Georgia Blue'

All veronicas, or speedwells, are undemanding perennials which love sunshine and well-drained, moist soil.

Introduced from Georgia by Roy Lancaster, Veronica umbrosa 'Georgia Blue' forms a low cushion of bronze-tinted green foliage, from which masses of intense blue flowers appear from late spring to autumn. It's ideal for edging paths or borders, and makes a fine specimen for a rockery. The RHS has given it its prestigious Award of Garden Merit.

Grow Veronica umbrosa 'Georgia Blue' in moist but well-drained soil in full sun. Cut back growth at the end of the season and divide congested clumps in spring or autumn.
