Penstemon Barrettiae
$4.10 / packet
In stock
Description
This rare, beautiful, and newly-introduced penstemon has thick, leathery bluish-grey leaves and long, tubular rose-purple flowers. In the wild it clings to cliffs and rocky outcrops and would make a beautiful introduction to gardens as it is hardy, drought tolerant, and easy to propagate. This seed was obtained from a reliable specialist nursery.
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.
