The original Kalanchoe was brought to Paris from Africa in 1927. In 1928 seed merchant Robert Blossfeld from the German town of Potsdam saw this Kalanchoe and turned it into a houseplant, which he introduced in 1932. His name was also attached to the plant: Kalanchoe blossfeldiana. The well-known houseplants are referred to as blossfeldiana breeds by growers. (via HERE)
Wish I had a Paris apartment to display these flowers/plants in!
