Wow... I can't believe they are already blooming! I don't even have flowers on the raspberries and I usually have my first round of berries come May. However, I did see flowers on my neighbor's blackberry canes, which she won't be happy about. She tried to have the canes cut out since they grow through her front walk. I may go try to cut them out for her again, we'll see.
For now, I'll stare jealously at your pictures and dream about blueberry season.
