This poem is beyond me, but I have learned that P. vulgaris is a carnivorous plant that grows in cold, rocky places. The last two verses say:

No finger plucks me for a maiden's wreath.
No girl takes me to the line dance.

And when I perish, I cause no pain.
I bloom and die for myself alone.

Yes, I doubt if anybody outside the Addams family puts carnivorous plants in a bouquet.
