I agree with Zuzu.
I was thinking for instance. I have no interest in Houseplants but I know Houseplants are very popular. But if I did grow houseplants I would grow African Violets. In fact I once did many years ago. But don't think an African Violets week would be overly popular so just include it in an article during Houseplant week. That would be if there is a Houseplant week.
That is why I like the Daisey's week idea. Can include coneflowers and all sorts of daisy type flowers.
And shade garden week can include all sorts of plants that thrive in the shade, not limited to one plant like Hosta week might be. But then Hostas are very popular.
