Is it Cheiranthus or Erysimum Bowles mauve?
Mine was labelled the latter.

I always knew it as the latter.
Both are informally wallflowers and are related.
Erysimum is ? Siberian wallflower ?

I bought my two plants as
Cheiranthus 'Bowles' Mauve' (also listed in the RHS encyclopedia under
this name)
and
Erysimum with no specific name. It is yellow-flowereed, has the same
plant size and flower stem length as Bowles' Mauve. I suspect that
it is E. x allionii. Who would want to gainsay me?

The RHS Encyclopedia treats Erysimum and Cheiranthus as separate
species.

Both of them are teeming with butterflies at the moment.
