Veronica longifolia Blauriesin

Veronica longifolia is an easy-to-grow perennial which prefers rich and light soil with a slightly alkaline tendency (limestone). It likes humid atmospheres and being close to water, but requires light soil. It develops and flowers better in the sun. Veronica longifolia can be planted almost all year round in the garden, except during periods of frost and summer drought. Cut back the faded flower stalks to promote new flowers. Adding compost to the base of the plant every spring gives it vigour. Avoid using nitrogen-rich fertilisers as they will weaken the vegetation and make the stems bend more easily. In late winter, cut the plant back to the base and fresh foliage will emerge in spring.
