Penstemon Pygmaeus Alba
This dwarf, shrubby, evergreen plant is a perfect choice for rock gardens, opening its pure white, tubular flowers in May, and it can continue flowering into autumn. Unless seed is needed, dead-heading after flowering will keep it compact and healthy.
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.
