Galanthus nivalis and Primula veris
A stamp issued together with another three by Romania in 1956.
Looking through my archives I came across photos of both plants.
The Snowdrop, Galanthus nivalis, was one the one and only Snowdrop I have ever managed to grow.
The photo of the Cowslips, Primula veris, was sent to me by a friend who snapped them near Pitlochry, in Scotland,
Both these plants are mentioned in THE MEDITERRANEAN GARDEN number 82, October 2015
