I don't believe Dickinson could have justified spending hours outdoors observing such things unless she was gardening. I could be wrong...
In any case, the article above introduced me to the exhibit Emily Dickinson's Garden: The Poetry of Flowers, which is jointly sponsored by the Academy of American Poets and the New York Botanical Garden. It's almost worth a trip down to the Bronx!
Instead of traveling, though, I can borrow Collected Poems of Emily Dickinson [811 DIC], Kate Greenaway's Language of Flowers [635.9 GRE] (Greenaway and Dickinson were contemporaries), or Garden Flower Folklore by Laura C. Martin [398.242 MAR].
Since it is now May, I thought I'd end with this Dickinson poem:
MAY-FLOWER.Head over to Random Noodling for this week's Poetry Friday Round-Up.
Pink, small, and punctual,
Covert in April,
Candid in May,
Dear to the moss,
Known by the knoll,
Next to the robin
In every human soul.
Bold little beauty,
Bedecked with thee,
