The poem seems to me a "parody" only in an older meaning of the word, not meant to ridicule anything. Rather, it describes the true artist as a kind of hermit, primarily striving to satisfy her/his own standards. In times of Corona, many of us have turned hermits against their will, others became virtual exhibitionists.

As for botany (in which, as usually, Google is my scholarship), the plant seems to be Helleborus niger. Needless to say that this one, like all others, is able to procreate; so are many apparently "hermetic" artists.
