Yes. Replace with say, summer bedding and you could replant with something else in early autumn with something like Pansies (Viola x wittrockiana), double daisies (Bellis perennis), or Sweet Williams (Dianthus barbatus). Leave replacing (in the same spot) the Wallflowers for one year as being related to Brassica's, they don't always do so well in the same spot.
