Found in higher elevation localities of inland Northern California, royal penstemon is a vibrantly colorful addition to the dry, full sun garden. In summer, the large, saturated blue-purple florets are held in clusters on stems rising almost 2’ tall above a low, evergreen rosette of glossy, strap-like foliage, reaching 1′ – 2′ wide. Attracts a multitude of pollinators. Does best with decent soil drainage, and inland sites that provide seasonality—colder winters, and hotter summers. Drought-tolerant once established.
