Veronica longifolia

Description

Veronica longifolia, commonly known as long-leaf speedwell, is a clump-forming herbaceous perennial that typically grows to approximately 2-4 feet tall, on stems clad with oval, toothed, medium green leaves. Lower leaves are opposite, but the upper leaves just below the flower spikes are sometimes whorled. Stems are topped in late spring to early summer by a showy bloom of small but abundant funnel-shaped, lilac-blue flowers. Sporadic re-blooming through to September can often occur.
