#SmellingTheBouquet Vanilla planifolia is the only orchid that bears edible fruit, and is endemic to SE Mexico & Belize. The cylindrical fruit pods containing tiny black seeds are the source of vanilla used in food and perfumery, commonly (and incorrectly) called beans. Pix: Shutterstock: Jiri Hera

#SmellingTheBouquet Vanilla comes from the fruit of the orchid Vanilla planifolia. Over 600ya, it was integral to the Totonac, Mayan & Aztec people in the plant’s native region of Mesoamerica. They practiced curing methods to enhance the aroma, making a paste to be blended with copal for incense.

But in the climbing ecstasy of thought, Ere consummation, ere the final peak, Come hours like this… —Nan Shepherd, “Summit of Coire Etchachan” published in WANDERERS: A History of Women Walking, by @kerriandrewsuk.bsky.social 11 Dec is #InternationalMountainDay #poetry www.un.org/en/observanc...
Summit of Coire Etchachan
Nan Shepherd

But in the climbing ecstasy of thought,
Ere consummation, ere the final peak,
Come hours like this. Behind, the long defile,
The steep rock-path, alongside which, from under
Snow-caves, sharp-corniced, tumble the ice-cold waters.
And now, here, at the corrie’s summit, no peak,
No vision of the blue world, far, unattainable,
But this grey plateau, rock-strewn, vast, silent,
The dark loch, the toiling crags, the snow;
A mountain shut within itself, yet a world,
Immensity. So may the mind achieve,
Toiling, no vision of the infinite,
But a vast, dark and inscrutable sense
Of its own terror, its own glory and power.
