Our cherry tree is in full bloom now, March 23, 2012. In 2011, the cherry tree came into full bloom around April 22. In 2010, peak date was April 4.
The first crocuses appeared on February 19 this year. In 2011, they showed up around March 17. I don’t have records for 2010.
From these two data points, it looks like 2012 is about a month ahead of 2011, but perhaps only 10 days or two weeks ahead of 2010. I’ll track the early native flowers in the next few weeks and see if this pattern holds true.
May 2, 2012 update: The Shooting Stars are at their peak now, just about two weeks ahead of their peak in 2011. Maybe the cooler, rainy weather of the last couple of weeks has slowed down the spring arrivals! Alas, my Pasque Anemone has not flowered this year. My guess is that dividing it last year took away the flowers this year. I do have a new plant under the plum tree, and the original patch, so I’m hopeful I’ll have blooms next spring.
