Clusters of pale blue to dark mauve, tubular, funnel-shaped flowers are borne from early summer until autumn on this showy much-branched plant. In the wild it grows up to nearly 5,000m in the Himalayas.
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.
