The angle of mid-day light.
It is a delight
at this time of year!
I have a theory about plants and light: they are like kids, they grow in the dark. It will need judgement by someone with more horticultural knowledge than I've got but my idea is that photosynthesis takes place in sunlight (of course) but growth occurs in darkness or shade.
We all know that sunflowers "turn towards the light." Well, why do they do that? My idea is that they are energized by photosynthesis but that growth takes place on the shady side. So, they are "pushed" towards the light. When the sun sets, the sunnyside of the plant begins to grow and pushes the plant back to the east - kind of, waiting for the morning sun.
So, what does this have to do with mid-day sunlight at the equinox? Probably not much but, hey, it is 4am! I'm trying to look on the bright side!! . . .
. . . Actually, it is kind of fun to look on the darkside - of plants, that is. Look south at mid-day and the leaves of the growing grass, especially, sparkle! At least here, the angle is so low that whatever is reflected off those freshly growing grass blades is coming right towards you! The plant's growth is dominated by the south because that is where most of the energy is coming from. You may have to wait a few weeks in more southerly locations but I think you will find it delightful to notice that.
