My verbascum 'southern charm' are floppy and not even flowering well. I planted them in sandy soil and have not fed them because I read somewhere that they like poor sandy soil. Is there anything I can do to help them?

Thankyou Loosestrife, I'll try that. Need to get some indoor potting compost first.

Replant them in indoor potting soil that contains a fertilizer in it. Lightly mist the soil so that it is neither too dry or too wet and see what happens then. Do not do any other application of fertilizer once you have done that.
