American alpine speedwell
Veronica wormskjoldii
American alpine speedwell is a delicate subalpine wildflower that produces charming blue-violet flower spikes in summer, best suited to cool, moist rock gardens or alpine troughs. It requires consistently moist, humus-rich, well-drained soil and cool temperatures, making it challenging to grow outside of mountain climates. Avoid hot, dry conditions and ensure good air circulation to prevent crown rot.
