More than 50 properties are showing off their snowdrops, driving footfall from locals and tourists alike.
New entrants to gala of Galanthus include Fyvie Castle in Turriff, House of the Binns in Linlithgow and Castle Kennedy in Stranraer. Dunninald Castle in Angus has returned to the festival after a break.
The festival, which runs from 28 January to 12 March is supported by VisitScotland and the festival is being organised for the first time this year by garden tourism organisation Discover Scottish Gardens.
Research shows that one in three visitors to Scotland make a trip to a forest or woodland park during their stay while 42% visit a country park or garden.
VisitScotland chief executive Malcolm Roughead said: "The festival provides a welcome boost for attractions during a traditionally quieter period of the year,"
Scottish Snowdrop Festival founder Catherine Erskine, from Cambo Estate, who is chair of Discover Scottish Gardens said: "We are very lucky in Scotland to have a fantastic climate for snowdrops, with many species thriving here and creating stunning displays. And this year, due to a mild winter, snowdrops are certainly popping their heads out earlier than they have for many years."
