Narcissus February Gold is a reliable early flowering daffodil. It's parentage is N. cyclamineus x pseudonarcissus. There are several dozen daffodil species in the wild but hundreds and possibly thousands of cultivars developed by plant breeders crossing and re-crossing different ones over time.
 Most are rather crass in my opinion but the act of hybridising one wild species with another has resulted in some pleasing varieties. Nature does this anyway sometimes though February Gold was probably given a helping hand back in the day; it doesn't seem to be recorded when or by who.
 It lends a splash of bright colour to the garden at this time of year when the sun is still in short supply.
