daffodil mystique

The daffodils have been up for about a week or so now propelling Athens into spring. The yellow wonders are so ubiquitous and ever lasting that sometimes they indicate where a house once stood. A new highway razes all structures in the way, but the buried treasures don't give away their location until March and go into hiding by June. 

The mystique came as I walked around town yesterday. How does a daffodil know which way to point its golden head. The likely answer is toward the sun, but I have some on the north side of my house that point north. Maybe the shadow of the house gives an indication and the flowers point toward what it thinks is the sun, the unshaded north. In my unscientific, limited observations, it seems that most flowers, if planted near a house will point away from the house, as if it knows where the observer will stand. But one planted in an open field could face any direction but most likely south. I wonder if I dig them up and turn them around will they point the same way or the way I turned them? 

Grow on.
