"Tommies" (Crocus tommasinianus) are usually a feature of February's round up of plants in flower along with Snowdrops and Winter Aconites. I must have planted hundreds in my garden in London over the years.

 The flowering has been brief this year, wilting in the hard frosts. Those in pots and containers in sheltered spots seem to have fared a little better than naturalised in grass and borders. But they're tough and will be back next year.
