I'd sure be willing to trade to a camellia..
Late winter and early spring blooms are the most important during the early part of the year,. Late summer and autumn blooms are just as important for storing food for the winter.
Also anything that blooms during a drought period in your area is also important because they will be more bees gathering water to cool the hive than there are gathering food.
If you are interested I have a database of plants for honey bees started on ATP's sister site Cubits. The link is below this post. You can search by common name, Latin name, type of plant, hardiness zone, and time of bloom. I also have articles on ATP written last year for the months of January through September that list plants that begin to bloom during those months. Just click on my user name to go to my profile pate and scroll down to find the list of articles.
The database is a work in progress and by no means complete yet.
