(Imperial Group). The third oldest extant snowdrop cultivar. In 1858, Frederick Bedford, head gardener of Straffan House, County Kildare in Ireland, found a snowdrop among G. plicatus that produced two flowers. The name 'Straffan' is not officially used until Bowles in 1956. It is a sturdy and late-flowering snowdrop, usually with two flower stalks. Clearly grooved inner petals, the mark is in the shape of a horseshoe.
