One of only a handful of plants endemic to Oklahoma, this is truly a special plant. Blooming late April to June with long narrow white flowers that open from yellowish buds it is found only in specific tallgrass prairie sites. Oklahoma Penstemon is a unique species in that its flowers have closed throats, opening with the weight of a honeybee, and limiting nectar access to large bumblebees. Help perpetuate the existence of this native perennial by growing it in a raised bed of unamended well-drained soil.
