Veronica longifolia

Veronica longifolia, commonly known as ‘longleaf speedwell’, is a hardy perennial from the Plantaginaceae family, recognized for its tall, elegant flower spikes and vigorous upright habit. It thrives in full sun, well-drained soil, and moderate fertility, offering long-lasting color from early summer through fall. Veronica longifolia is well-suited for perennial borders, cottage gardens, and pollinator-friendly plantings, adding vertical interest and continuous blooms to the landscape.
