I also treat these as annuals. Mine, planted last October, have been flowering ever since, through rain, snow and frost. They are still going strong,in pots, underplanted with spring bulbs which are all coming through now. The two flowering together will look great. I much prefer the little violas to the winter pansies. I expect mine to last at least until May when I change the pots to summer flowering plants, then they go in the compost bin.
