What's in flower on 1st of month?

I've got busy lizzies, marigolds, tagetes, gazania, salvia, dahlia, Japanese anenome, begonia tuberous & fibrous, antirrhinum, penstemon, sedum, cyclamen, polyanthus,yellow buddleia and a couple of roses. Admittedly all are a bit confused by the weather, bedraggled and neglected. I may have a single tomato flower on a forgotten plant in the gh, does that count? Also a rather magnificent Christmas cactus indoors.
