Can we skip to the part when it's spring again! Ever wonder why flowers bloom at different times? The weather warms up, the snow pack melts and flowers emerge. But they don't all come on and bloom in the same week. So, what tells them to bloom every year at around the same time? Scientists believe that plants have an internal circadian clock that helps them know when sunlight is increasing and days are getting longer. They believe this internal clock works because of proteins that work as photoreceptors activated by sunlight. This was first suspected by scientists in the 1930's who called this protein chemical "florigen". Once the photoreceptors proteins tell the plant to bloom, a molecular process begins to create the bloom. Specifically, the plant begins to produce a protein they now call "Flowering Locus T" in their leaves. The protein then travels to the tips of shoots, where it undergoes molecular changes that spur cells to begin to form flowers. In a nut shell, they're smart. They have an intelligence we don't yet know or understand as 'scientists'. However, people have been communicating with them for centuries. We have learned when plants bloom and when its best to harvest them, with permission, for their highest yield of benefit to us. So, what about you? If you were a flower, when would you bloom?
