Erysimum Bowles Mauve is one of the longest flowering Wallflowers available. Bowles Mauve can flower from as early as April and has been known to flower until at least October. If it is in a very sheltered city/town garden it can flower for even longer.
Bowles Mauve has grey/green foliage topped with long spires of purple flowers. It is a great plant for pollinators.
