This penstemon selection shares complicated genetics with the other similar popular garden penstemons. It is likely that these hybrids were derived from a combination of P. hartwegii, P. cobaea, P. isophyllus, P. gentianoides and/or P. campanulatus. All these hybrid selections are extremely showy and relatively durable in the garden. ‘Midnight’ is a tall, vigorous selection, combining broad, deep green 4 inch leaves and velvety purple flowers. It will bloom in repeated waves from late spring to fall, carrying large, bell shaped blossoms in thick spikes. It was selected by Nevin Smith at Wintergreen Nursery. Best in sun, in reasonably well drained soil with moderate watering.
