Overwinter Erysimum Bowles’s Mauve?
Good evening! I planted Erysimum Bowles’s Mauve in the spring which was lovely but now looks somewhat lacklustre, as you’d expect. Can I move these out of the border for winter and put them back in spring? I realise I can only expect 2 or maybe 3 seasons from this plant and have taken cuttings to see if I can grow new plants for 2021, but ideally I’d like to look at something prettier over the winter. Any recommendations much appreciated thanks!
