Penstemon  Blue Midnight

Penstemon Blue Midnight

Penstemon Blue Midnight (Midnight) has medium sized dark purple blue flowers and medium width foliage. Of all the garden hybrid Penstemons, Blue Midnight along with Penstemon Garnett have been the most cold hardy for us. The plant has narrow leaves that may indicate the influence of Penstemon campanulatus or Pestemon kunthii in its genetic makeup. An ideal candidate for adding to moss animal topiaries. All of the garden hybrid Penstemons need full sun and well drained soil. We mulch the crowns with 1 and 4 to 10 crushed gravel which discourages crown rot by letting water drain off the crown quickly. When planting Penstemons we fertilize them only lightly and then never again. Over fertilizing Penstemons promotes the development of lush soft growth which leads to excessive die back in the winter. Seasonality is Summer to first frost. Measurements are around 2.5 feet x 3 feet Colors are Dark Purple Blue flowers Hardiness Zones: 7, 8, 9
