Here in the tropics there’s a shrub that bursts into sensational bloom in the heart of winter. It’s called the snowflake shrub*: when flowering, it resembles a mass of delicate white snowflakes.
The interesting thing about this shrub is that if you plant it beside a light source that isn’t natural – like a street light – it refuses to flower.
It will only flower on the side away from the artificial light.
It only responds to the real thing; artificial input shuts down its natural instinct to bloom.
I bow deeply before the savage wisdom of this little shrub.
