A tall, upright perennial with narrow leaves and spikes of small blue or purple flowers held above the foliage. It's excellent for adding vertical structure to borders and attracts pollinators.
Why grow it
Long-leaved Speedwell offers reliable vertical accent among lower-growing border perennials, with flower spikes that persist longer than many Veronica species. Its narrow foliage creates a finer textural contrast compared to broader-leafed companions, and it tolerates average garden soils without demanding rich fertility or supplemental feeding.
Watch out for
Plants may become leggy or decline in vigor after several years and benefit from division every 3 to 4 seasons to maintain compact form. In humid climates with poor air circulation, powdery mildew can affect foliage, though this is typically cosmetic rather than severely damaging.
