I'd be grateful if you, or anyone, could point me to a good resource for identifying tiny flowers, especially wildflowers. I have the Audubon guide to wildflowers of eastern North America, but the coverage is limited, so we wind up saying "it's those purple ones we don't have a name for" and "I found some blue flowers that look like a child's drawing of a flower" in between "there are violets" and "the dandelions have started ridiculously early" (by which I meant early February).
