Wallflowers as a potted specimen

historyman

I have just recently watched a repeat of Carol Klein where she planted up a large container with wallflowers etc. Any advice how can I achieve a single large specimen of wallflower in pots. I have always bought them bare rooted - can one of these be coaxed on to make a specimen plant?
Thank you

Carol was using perennial wallflowers, Erysimum, which are woodier than the biennial wallflowers and make a more substantial plant. My Bowles mauve  was nearly a metre high and wide, but some others are a bit smaller. I have seen Orange Twist, but haven't 'met' the one she used. They cost a bit more to buy, but last longer, though they are not very long lived. My BM went a couple of years beyond its expected demise though

I've always found individual bedding wallflowers (not the shrubby ones like Bowles' Mauve" to be rather thin plants, best planted en masse. You could perhaps try several plants spaced out in a big container.

Thank you for that info. I do have Bowles mauve, but it rather a large shrub. I will look out for the Orange Twist.
