These stamps and the souvenir sheet will be issued April 9th. From Israel Post: The issue “reflects that season and the element of revival.
“The flora of Israel includes some 2700 species, more than half of which bloom in the spring. The springtime conditions suit and encourage the development of flowers as well as the plethora of insects that visit them. Spring flowers come in different sizes, colors, shapes and scents. Their characteristics attract different insects. Competition among flowers during this blossoming season leads to the evolution of different shapes and colors.”
