SHOWY is right! The gorgeous purple foxglove-like flowers are around 2" each and cover more than half the 2 foot height of the plant during the bloom season (May through July). Likes sun, well-drained soil, and is drought tolerant once established. Attracts pollinators, hummers, and hosts checkerspot butterfly larvae.
