Why is it customary to give flowers on March 8? Roses, chrysanthemums, carnations and other flowers fade into the background when it comes to March 8. Mimosa became the symbol of this day. Although it is not known for certain why. Perhaps because it is she who first blooms after the winter cold and in many countries symbolizes the onset of spring. The tradition of giving mimosa on March 8 came from abroad. This plant is not afraid of frost, and can withstand up to -10C. But girls may like different flowers, so on such a day you can move away from traditions and give your favorite flowers for your significant other, even if it's not a mimosa!
