Plant Story: Not Always Just Plain Vanilla

     Good vanilla is one of my favorite flavors, and the idea of "plain vanilla," vanilla as the no-flavor flavor, has always been somehow annoying.  And it wasn't always the case.

The vanilla orchid is the plant in the middle,
hanging down over the tree branch. (In the
Conservatory at the Smithsonian in
Washington D.C.)

   Vanilla is native to the Americas and although probably in use for millennia there, it only reached Europe after 1492. At that time it was a rare and highly desirable flavor.


   Vanilla comes from “beans,” long thin bean-like pods, but vanilla is not at all a bean (legume, plant family Fabaceae), but an orchid (plant family Orchidaceae). In fact, it is the only orchid used as a food, or used by commerce in any other way than as ornamentals (flowers) even though there are more species of orchids than species in any other plant family, legumes and grasses included.  

   Vanilla is a climbing vine with fleshy leaves longer than my hand, but 2-3 fingers wide. We grew a vanilla orchid in the greenhouse at the University of Nebraska. It climbed up to the ceiling. Then its stem connecting it to the pot broke, so the plant was hanging from the wall and ceiling without being rooted in soil at all. It lived like that for years. And that was fine until we wanted to move it...which is of course one function of flowerpots, mobility.

      The flowers of the vanilla orchid are cream-colored recognizable orchid flowers ( vanilla flowers on Google).  The fruit develops as long dark pods.
