Aster family STEM
For any of you that aren't current, we're not talking about plant stalks. STEM is science, tech, engineering and math. It's an acronym in common use in today's schools. Aster family plants are amazingly well schooled. Their math, physics and chemistry work together to determine how many spirals there will be in the discs. The math part is the Fibonachi sequence; 0, 1, 1, 2, 3, 5, 8, 11, and so on. Each number the sum of the previous two. The physics and chemistry of translating this into flowers is way beyond me, but not beyond the daisy!
