The perennial wallflower ‘Bowles Mauve’ is just showing its first purple flowers of the year. I expect a show from now until October and as the flowers drop off the bottom of the stem but continue to open further up I will snip them off as there will be more stems thrown up. The plant is related to the biennial wallflower but has this constant performance rather than one quick hit. It isn’t as scented as other wallflowers.

Yellow ‘Dwarf Erysimum’.

Tips

• It is vigorous making a 3′ mound in the first year but becoming leggy & woody in future years.
• Fortunately it is easy to propagate from from cuttings
• It is worth putting a few in a pot or in a spare patch in case the parents don’t survive a hard winter
• It will thrive in poor soil and flower well after deadheading.
• It can suffer from club root so don’t compost infected plants and don’t replant in the same spot
• Try other Erysimum such as ‘Moonlight’ or ‘Gold Shot ‘  yellow flowers
• Bowles Mauve is 30″ tall, evergreen with blue grey leaves and can flower in every month of the year in a mild winter

• It can be grown from seed as well as cuttings T&M

• Wallflower Seeds

 

Other Erysimum

• Erysimum Constance Cheer has dusky orange flowers that fade to smoky purple. It grows 14″ tall and is less woody than Bowles Mauve.
• Erysimum Parish’s has almost black buds that open deep red then fading. It grows taller at 2 feet high.
