Penstemon kunthii

One of our very favorite of all perennials at Xera. This extraordinary Penstemon is actually native to south central Mexico, but glory be its actually cold hardy here. Smaller, profuse tubular intense red flowers line strong stems. This bushy plant expands with the season and there will be scores of bloom spikes. To 2′ x 2′  but it can and has exceeded that. This EVERBLOOMING perennial is incredibly adaptable as well as an almost over performer. The flowers are small enough that they create a haze of red rather than a wall of red and it finds color compatibility with purples, and oranges. Full sun in rich to average soil that is never boggy. Slight improvement to the soil will result in a cloud of flowers for months. Irresistible to hummingbirds and pollinators in general.  Bloom which is constant can even extend well into winter shrugging off light frosts. Considering its native origin in Oaxaca its fantastic that it thrives to perfection in our climate. So far its happily weathered temperatures down to 5ºF. This is a outstanding perennial with a sophisticated flower color and a massive display of bloom for months. Cut back by 2/3 in early spring. It will resume growing almost immediately. We obtained this plant from our friend David Mason and we are forever in his debt. Glossy thin foliage is handsome.
