My husband is a botanist who has been watching our yard for the past 5 years. He has compiled a rather extensive data-base of almost 250 species of plants on our one acre yard. He has also started a blog, which he is posting regularly about currently blooming plants. He is very funny to read and it would be cool to see other naturalists around the world connect about the plants in their neighborhoods.
Go here to see a botanist's renaming of the seasons based on observation. He is up to 5 so far, starting March 26.
