I started this thread "Spring Crocus 2010" to post photos and information on the popular spring crocus. This year has been the mildest and earliest spring flowering ever, advancing the season for "first bulbs" by two full weeks over the last 10 years, with lots of species and hybrid crocus pushing the season to an extraordinarily early start. One species that is barely visible one day and all of a sudden after a warn day leaps forward into full flower is Crocus kosaninii.
I received the plant as C. biflorus ssp. pulchricolor, however it is a mistaken ID, the plant illustrated is most likely C. kosaninii. The first photo shows early anthesis with lots of very small perky flowers, with many more buds coming. It is a bee magnet.
