Penstemon procerus, Small-flowered Penstemon

From early to late summer, pink-purple-blue, tubular blooms burst forth in whorls on upright stems. Leaves form a low mat of narrow, evergreen, grey-green. Native to W USA. BEE-loved. Note: Penstemon procerus, like many Western natives, may enter a semi-dormant state in the hottest part of the summer but usually returns to bloom with the start of the rain.  Mature size: 2-12 in T & W Minimum temperature: -20° F Photo of flower close up by Peter Stevens from Seattle, CC BY 2.0, via Wikimedia Commons Photo of blooms & leaves Matt Lavin from Bozeman, Montana, USA, CC BY-SA 2.0, via Wikimedia Commons
