I enjoy reading your accounts of which plants are feeding the bees in your warmer climate.
Some of those plants either:-- do not grow well here in zone 3, or they flower later here.
I am wondering if there is a source for info suitable for northern climates?
I would especially like to find some which flower early in the season when bees first show up in spring. And also for the end of season too.
In the mid season there are lots of flowering plants.
