Penstemon Hirsutus Minimus
This rare and tiny plant has long pale purple tubular flowers, darker on top, in early summer. Making a compact cushion of small-leafed stems, it is ideal for a small rock garden or pot on the porch, and although bone hardy from the cold, it prefers a dryish, wel-drained spot.
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.
