Wednesday/ a touch of spring

We had 58°F (14°C) at the high here in the city, and sun all day.
The little crocuses with their flowers have popped out of the ground, just a little bit later than they were last year.

And how do they know when to flower? It’s very complicated. Flowering plants have a master gene called APETALA1 (AP1). A combination of sunlight, soil temperature and water, prompts the AP1 gene to generate proteins, which in turn, switch on more than 1,000 other genes that are involved in the flowering process.
