Two days after Christmas, the Pink Pearl hyacinths have really filled out. I guess pink hyacinths are the earliest. My earliest blooms in past years were Ann Mary, also pink.
Purple Sensation are also early.
Even after all my obsessive record keeping I found I had a number of question marks for which variety was in which vase and have tried to sort them the best I could, below. I guess I was in a hurry to get the vases in the cellar after waiting so long for the bulbs in September. And I was still buying vases and bulbs until the last minute so things got confused.
As of December 27:
Delft Blue
City of Haarlem
Sky Jacket
Aiolos
Blue Star
