Veronica longifolia | Long-leaf Speedwell ‘First Glory’
Long-leaf speedwell, sometimes called Garden Speedwell, is an upright, herbaceous perennial that forms a low mound of attractive lance-shaped green leaves with upright stems bearing numerous tall, tapered spikes of deep blue flowers that rise well above the foliage. The showy flowers reach up to 14 inches tall and typically bloom from June to August. They are attractive to bees and butterflies.
The genus name honors Saint Veronica who reportedly gave a handkerchief to Jesus so he could wipe sweat from his face on the way to Calvary, with some plants having markings that resemble the markings on the sacred handkerchief.
Grows best in average, consistently moist, well-drained soil in full sun. Requires adequate winter drainage. Will tolerate light shade. Deadhead for repeat blooms.
Ideal near the border edge, in containers and rock gardens. Spreads via slow-growing root-stock and self-seeding.
