green shoots

Watching this plant recover and slowly start to grow again once moved from the window sill to the balcony, it's new bunch of leaves ready to unfurl like something inchoate from a chrysalis, and the venerable, old cactus sprouting a new pseudo pod, has got me think about the different cues of light and temperature that plant-life has outside of seasonal fits and bursts. Perhaps there are things more subtle in the senses that yield good horticulture and horticulturists.
Our geraniums were looking a bit unremarkable, healthy but late-bloomers, and learned that if during transportation, the flowers are kept in the dark for more than forty hours, they hold off on further growth after the first spurt. Despite any amount good care and coaxing, they need to normalize their cycle on their own terms. That too made me think about the curious story of tropical poinsettias (Weihnachtsstern), which will only flower or develop those trademark red leaves when exposed to equal amounts of diurnal sunlight and dark night, like the conditions near the Equator.
