If you’re anything like us, you may be sad to see the summer blooms come to an end in the Northern Hemisphere.
How do flowers know when to bloom (and when to stop)? When environmental conditions are optimal for reproduction, flowering plants send proteins to their growing shoots. These proteins signal to the developing plant tissue that it should become a flower, rather than a leaf. As the days grow colder and shorter, these proteins can be stored, halting flowering until conditions are favorable again.
So fret not! The blooms will be back in spring, when light, temperature, and other conditions are just right.
