Crocus tommasinianus, the woodland crocus, early crocus, or Tommasini's crocus, is a species of flowering plant in the family Iridaceae. It is named after the botanist Muzio G. Spirito de Tommasini (1794–1879). It is native to Bulgaria, Hungary, Albania, and the former Yugoslavia. It is often referred to as the early or snow crocus, but these terms are shared with several other species, although C. tommasinianus is amongst the first to bloom. Multiple plants are often called tommies in the horticultural trade.
