Penstemon Confertus
In stock
Description
This very rare but surprisingly easy-to-grow species, bears densely crowded spikes of a true lemon-yellow, making it the only genuinely yellow penstemon. In the wild it grows locally in moist open or wooded places, sometimes in meadows or by streams, and in lowlands and foothills in the Rockies, as well as in Montana and Alberta to British Columbia, Oregon and the Wenatchees of Washington. Very few seeds collected.
Sowing Advice
Seeds can be sown at any time but are best sown in winter or early spring to benefit from a cold spell in the wet compost to break their dormancy. We advise covering seeds very thinly with sand or fine grit to about the depth of the seed size. If the seeds do not come up within 6 to 12 weeks the damp seed tray can be given cold treatment in a fridge for about four weeks. They may still take very many months to appear, so please never discard the pot or tray.
