Poor little Heart — Floating-Heart

This poem describes a plant called heart-leaf, or floating-heart. The last stanza shows Dickinson's intention. As the only one (like a floating-heart) who cared about her poems, she arrayed them with twisting and bright words.

Poor little Heart! 1
Did they forget thee?
Then dinna care! Then dinna care!

Proud little Heart! 4
Did they forsake thee?
Be debonnaire! Be debonnaire!

Frail little Heart! 7
I would not break thee-
Could'st credit me? Could'st credit me?

Gay little Heart-10
Like Morning Glory!
Wind and Sun-wilt thee array!
(F.214/J.192)
