VERONICA Rockery Speedwell

If drainage is satisfactory then you will have no trouble with Speedwells – no trouble to grow them, but you may well have difficulty in keeping them under control. Many are exceedingly invasive, like the small Speedwells in the lawn. The larger Speedwells are grown in the border , but a few of them, such as V. incana and V. teucrium, are occasionally planted in the larger rockery.

VARIETIES: The basic Rockery Speedwell is V. prostrata – height 4 in., spread 1.5 ft.

Flowering period: May- July. The basic colour is blue – choose from ‘Spode Blue’, ‘Kapitan’ and ‘Royal Blue’. There is also ‘Alba’ (white) and ‘Mrs Holt’ (pink). V. fili-formis grows only 1 in. high but it will quickly carpet an area of 3 or more sq. ft – definitely not for the small or choice rockery. For a non-aggressive ground cover, choose V. pectinata (height 3 in., spread 1 ft.

Flowering period: May-June). Blue and pink varieties are available.

SITE AND SOIL: Any garden soil – thrives in sun or light shade. PROPAGATION: Divide clumps in spring.
