There really is no such thing, winter-blooming daffodils. There are species of daffodils that bloom early, in the past sometime mid-March, depending on weather. A good rain, even with cold temperatures, could coax greenery out of the ground long enough so that sunshine would bring a bud to the surface.
This year, traditional blooming patterns are kicking off the year even more unpredictably than they were last year. Hellebores, which usually start blooming mid-January were not setting bud until a month later. Daffodils, which don't bloom until mid-March, the beginning of spring, were nodding their bright yellow heads a month early, which inspired me to call them winter-blooming. That was also confusing because although mid-February, temperatures were in the 60s, breaking yet another record for the warmest recorded days.
Ok, I'm not loosing my mind. According to the National Phenology Network, "spring continues to arrive three or more weeks early – now making an appearance in Missouri, West Virginia, and the southern parts of Illinois, Indiana, and Ohio. Washington DC is 22 days early."
USA National Phenology Network has a simple mission: "We bring together citizen scientists, government agencies, non-profit groups, educators and students of all ages to monitor the impacts of climate change on plants and animals in the United States."
Nature's Notebook, a citizens involvement program, is quantifying what gardeners and beekeepers have been doing for years, collecting observations and comparing notes. In the case of spring-time, they are suggesting this trend will continue:
"By mid-century, early springs and late-season freezes will likely become the new normal, which may result in more large-scale plant tissue damage and agricultural losses."
Let's hope we also will continue to have winter-blooming daffodils. Hard to think of spring without lovely yellow cheery daffodils.
