Eine Blume, die es gerne warm mag

Fast unglaublich, es gibt Blumen, die sich selbst so einheizen, daß sie 35° wärmer als die Umgebungstemperatur sind und das alles nur um flotte Hummeln anzulocken.

Plant Physiology Online: Temperature Regulation by Thermogenic Flowers: "Over 200 years ago the French biologist, Jean-Baptiste de Lamarck, wrote that the blossom of a European arum lily warmed up during the sequence of blooming. Since then, botanists have recorded significant self-heating in the flowers, inflorescences or cones in several families of plants, including the lotus (Nelumbonaceae), many species of arum lilies (Araceae), and a few species of water lilies (Nymphaeaceae), Dutchman's pipes (Aristolochiaceae), palms (Arecaceae and Cyclanthaceae), custard apples (Annonaceae), magnolias (Magnoliaceae), Illicium (Illiciaceae), Rafflesia (Rafflesiaceae), winter's bark (Winteraceae) and cycads (Cycadaceae).
