Erysimum 'Bowles Mauve' (or "Cheiranthus" as it used to be known) is one of the perpetual favourite garden flowers. But it has invariably been sterile producing no seeds, or at the very most the odd one. We now have a strain that DOES produce seed, so you can grow new forms for yourself and propagate the best ones from virus-free cuttings! All habits, from tiny to tall, and colour variations, including some bi-colours, from pale mauve to deepest purple.
