Veronica longifolia

Veronica longifolia is an easy-going perennial that prefers rich and light soil with a slightly limestone tendency. It likes humid atmospheres and being close to water, but needs light soil. It develops and flowers best in the sun. Veronica longifolia can be planted in the garden almost any time of the year, except during periods of frost and summer drought. Cut the faded flower stalks to promote new flowers. Adding compost at the base of the plant every spring gives it vigour. Avoid using nitrogen-rich fertilisers as they will weaken the vegetation and make its stems more prone to bending. In late winter, cut the plant back to the base and fresh foliage will emerge in spring.
