Azure blue spikes
This upright herbaceous perennial forms generous clumps and in early summer produces a multitude of tubular flowers borne on long spikes.
Veronica longifolia (long-leaved Veronica) is native to the northern hemisphere, from Northern Europe to Siberia, China and Korea. It prefers damp conditions (wet meadows or waterside).
Not to be missed, it's a great addition to a mixed border to contrast with perennial Achillea, Echinacea, Helenium and geraniums (flat / spike flower contrasts) or behind varieties with a rounded habit (Phlox paniculata, Artemisia). For the best effect, we recommend planting in groups of three, five or seven.
Veronica longifolia 'Blauriesin' produces deep azure blue flower in July (Height of the foliage: 40 cm. Height of the inflorescences: 70 cm.
Easy to grow in good, not too dry, garden soil in the sun or slight shade. It can cope with damp, heavy soils if you add drainage elements when planting.
Maintenance: prune the dried inflorescences to encourage a second flowering in August-September. Mulch with leaf mould at the beginning of spring. Divide the clumps every three years in the autumn.
