As befits a diary based around the four seasons there is a cyclical aspect to these entries. Thus I generally note the emergence of this patch of Winter Aconites (Eranthis hyemalis). They appear on a particular verge in Hertfordshire round about now, give or take a week or two depending on the weather.

 Most years I make a point of walking out from Hitchin to look at them; a cheerful sight with their bright yellow flowers and ruff of green.
