Wild Daffodils start flowering when the soil temperatures reach around 10C, usually in February or March. In a warm winter like the one we've mostly had this year, we are seeing buds nearly ready to open at the start of February.

The earliest flowering cultivars (cultivated varieties) of Daffodil reliably flower earlier, even in January sometimes.
