Veronica longifolia - Long-leaf speedwell

Veronica longifolia is a striking plant as it develops flower spikes that take the plant’s height to an easy 4 feet. Generally hardy to at least Zone 4, long-leaf speedwell tolerates average everything but will thrive in richer, moister soil than average. It also will benefit from deadheading, encouraging more blooms for a longer show, which usually starts sometime in July in Maine. Tiny blue flowers cover the racemes, and as pictured above you can see the flower has tipped sideways due to the partial shade conditions under which it is growing. To keep the blooms upright, plant in a full-sun locale or stake the plants to keep them from tipping.
