Today was officially the first day of spring. I never usually pay attention to the official dates as our Gregorian calendar seldom syncs with nature. I prefer to use the cues that nature provides as I need to know when to plant the spring crops without a late frost hitting the seedlings.
The most accurate indicator has been the exotic Liquid Amber (Liquidambar styraciflua) tree in our garden. It can be seen in its autumn foliage in the photo at the top of the page. The buds only break once Spring really has set in and no more frosts are expected. So far it has not let us down. I know that day length plays a large plant in a plants sensitivity to season but I would like to know what other mechanisms may play a part.
The photos were taken today on a Blackberry phone.
