What is the proper way to cite a title of a poem, written in lowercase, from a book of poetry using MLA?

If the title of the poem were "apple and trees," would it be best to write it as "[A]pple and trees," or is there a preferred method?

The MLA Handbook (8th ed.) 1.2 Titles of Sources (emphasis mine):

Whenever you use the title of a source in your writing, take the title from an authoritative location in the work, not, for example, from the cover or top of a page. Copy the title without reproducing any unusual typography, such as special capitalization or lowercasing of all letters.

In other words, MLA says to ignore the unusual lowercasing and present it as you would any other title.

In this case, the title would be cited as Apples and Trees.
