Description

This is the true, large-seeded form of the truly dramatic species, that opens its spires of dazzling, blue-purple flared flowers on strong stems which carry thick leathery foliage. Although this plant is frost hardy, it absolutely demands a dry spot if frozen in the winter. 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.
