Veronicastrum virginicum 'Red Arrow' brings bold vertical structure with slender, branching flower spikes that read as white to pale blue in bloom. You will see whorled, lance-shaped leaves stacked along upright stems, giving the plant a strong architectural look even before it flowers.
Plant it in full sun for the sturdiest growth, and keep the soil evenly moist, especially during its first seasons. This is a perennial that can be slow to settle in, but once established it becomes a dependable, long-lived accent. It performs well in average to wet, well-drained soils and is a natural fit near low spots that do not dry out.
At maturity, expect it to stand about 36-48 inches tall with an upright habit and a moderate footprint. If you grow it in too much shade or in soil that dries, stems can lean and may need support. A mulch layer helps even out moisture and protects the root zone in hot weather.
Use 'Red Arrow' as a vertical anchor in borders, meadow-style plantings, and native-inspired gardens. It pairs well with moisture-loving perennials and grasses, and its flowering stems offer good seasonal height without looking heavy. Deadhead spent spikes to extend the show, then cut back after flowering for a tidy look and fresh basal growth.
