Erysimum mutabile Lemon Delicious
Clusters of lemon flowers fading to cream top this lovely wallflower, narrow grey green leaves on a stout little hardy shrub.
I found this one in an old garden in Victoria some years ago and have been trialling it ever since, soundly perennial, it's a favourite with the bees and me. It just needs an odd trim to retain its shape.
