Dark Blue Speedwell
Veronica longifolia ‘Vernique® Dark Blue’
Dark Blue Speedwell is celebrated for its vibrant, deep blue-violet flower spikes that stand like bold exclamation points in the summer border. This hardy perennial combines intense color with a tough, adaptable disposition. Forming a compact clump of greenery, it delivers weeks of dramatic, pollinator-attracting blooms with very little care, making it a classic and dependable choice for adding cool-toned drama to sunny landscapes.
Vivid Blue-Violet Flowers: Produces strikingly dense spikes of deep blue to purple flowers that command attention from early to mid-summer.
Long Blooming & Compact: Offers a generous flowering period while maintaining a manageable, clump-forming habit, typically growing 1 to 1.5 feet tall and wide.
Tough and Reliable: Highly resistant to deer, drought, and heat once established. It is also winter-hardy and not prone to pests or diseases.
Versatile Sunny Spot Perennial: Performs best in full sun. Ideal for mid-border placements, rock gardens, and informal naturalistic plantings. Attracts butterflies and bees.
Effortless Garden Performer: Requires minimal maintenance. Deadheading can prolong blooming, and the plant can be cut back in early spring for tidy new growth.
