Lewisia Tweedyi Alba

Description

This is the very rare form of one of the most exquisite of all alpine plants, these gorgeous specimens opening large pure ivory-white flowers in April and May above fleshy evergreen leaves. Mature plants can flower at any time right into the late autumn. They are surprisingly bone-hardy with frost, but prefer to be kept in a pot in the alpine house or on a window sill, or grown on a sheltered scree bed or trough in the garden. They always prefer a rich well drained soil where the crown can be kept dry. Just a very few individual fertile seeds are collected each year which come 100% true white.

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.
