There is a large range of dates when the first ones flower, although I've only been noting dates down in my garden diaries recently. But by far the earliest was the year we moved in (1994) when the first one was out on December 30th.
Of the dates I did note, the latest was 2014 when it took until February 16th and February 14th in 2011, but the average is around the January 20th.
I'll take a photo when it stops raining (not forecast until Friday)
