One of the very choicest of all penstemons and a challenge to grow, this fabulous semi dwarf plant opens largish flowers of the most intense sky-blue from crimson calyces. Native to the foothills of the Rockies, and adapted to sunny, dry conditions, the leaves are an attractive blue-grey. This is probably the earliest of all penstemons to bloom, in the wild flowers often emerging in late April, sometimes being covered with a late snow. Must have perfect drainage, and is a good contender for a pot for the spring show-bench. Very few good seeds collected.
Seeds are best sown in winter or early spring as they benefit from a cold spell in the wet compost after sowing to break their dormancy. We advise covering seeds very thinly indeed with sand or fine grit, a good guide is about the depth of the seed size. They may also be sown at any time and if the seeds do not come up within 4 to 12 weeks the damp seed tray can be given cold treatment in a fridge for about four weeks. These seeds may still take several months to appear so please keep the pot or tray safely. This plant will not stand winter wet!
