Long Leaf Speedwell is a clump-forming perennial that brings months of continuous color to sunny borders, blooming from June through September with abundant lilac-blue funnel-shaped flowers on tall, architectural stems. Growing 36 to 48 inches tall and spreading 12 to 24 inches wide, this hardy perennial thrives in zones 4 through 8 and attracts butterflies and hummingbirds while remaining unappealing to deer and rabbits. Its medium green, lance-shaped leaves create a sturdy presence even when flowers fade, and gardeners appreciate its cut-flower quality for fresh arrangements.

The real draw here is the extended bloom season, June through September, delivering weeks of pollinator-friendly flowers from a single planting. Lilac-blue spikes rise on strong stems above deeply toothed foliage, creating a naturally architectural presence that doesn't require fussing. Deer and rabbits leave it completely alone, making it a reliable choice for gardens where wildlife pressure is constant, and removing spent flower spikes triggers repeat blooms rather than requiring you to wait for next year.
Long Leaf Speedwell excels as a cut flower, with sturdy stems and showy spikes that hold up well in arrangements. In the garden, it functions beautifully in mid-to-back borders where its height can anchor color schemes, and its pollinator-magnetism makes it a thoughtful addition to gardens designed to support butterflies and hummingbirds.

Remove spent flower spikes regularly to trigger repeat blooming throughout the season. Every third year, lift and divide plants, working in fresh compost and manure to maintain strong growth. In areas with less than full sun, taller plants may need staking to prevent flopping, particularly if soils are overly rich.
