"Nobody knows this little Rose--" is the first of the twelve Dickenson poems that are known to have been published during Dickenson's lifetime. It was published anonymously in the Springfield Daily Republican under the title "To Mrs. ---- with a Rose." The poem was heavily edited compared to the original version in Dickenson's own writing found in her fascicle. There is no acknowledgement in any of Dickenson's letters that she approved of these edits, or even the poems publication, leading some scholars to theorize that these things may have been done via a third-party actor without her consent.
