Avoiding SAD - Visit a Greenhouse

Seasonal Affective Disorder, the winter blues, has never gotten me down, although winter simply goes on too long. But one certain remedy is to spend some time in the nearest greenhouse. All that organic material, the humidity, the smells of plants and earth, have a very salutory effect upon your brain. Maybe this is why botanists are not too prone to depression?

So while curing my SAD today this beauty caught my attention - Thunbergia mysorensis. Sorry if it has a common name, it isn't known to me (anyone?). The inflorescences hang down nearly 2 feet and the colorful flowers open bottom (which is at the top) to top, but this poses a problem for such flowers because usually their stamens and stigma are on the dorsal side of the flower. This is solved by having the flowers rotate on their stalks 180 degrees. This is not uncommon and other plants with dangly inflorescences do the same thing (e.g. Wisteria). Note also how the red calyx contributes to the overall display. You can grow this outside in warm climates.

Relief from winter doldrums: 2. Visit the greenhouse


Lincolnland is still in the grips of cold and snow, although it does look pretty right now. Usually the midwest is just sort of snowlessly bleak. But for the second in my series on seeking relief from the winter doldrums, let's visit the greenhouse and see what's going on that isn't monochromatic.

This is a pretty spectacular flower, Thunbergia mysorensis. As the specific epithet suggests, this vine is native to southern India. A pair of reddish bracteoles encloses the base of each flower providing a constant display as the flowers open sequentially bottom to top. Morphologically; the inflorescence is pendent so the bottom is at the top and each flower twists 180 degrees to attain the correct orientation. The flowers produce copious nectar, often enough to drip over the bottom lip of the corolla, and are bird pollinated. The stigma and stamens occupy the top of the corolla tube where depending upon the stage of flowering (pollen accepting or pollen dispersing) one or the other makes contact with the visiting bird's head. Enjoy.
