I think Chat-GPT might help out:
Entropinnium" could be a fusion of "Entropy" and "Petunium." In this case, "Petunium" might be a fictional flower with characteristics inspired by the concept of entropy, like vibrant and unpredictable color patterns.
Another option could be "Entropinnium" combining "Entropy" with "Dianium." "Dianium" is a fictional name inspired by the genus "Dianthus," which includes flowers like carnations and pinks.
"Entropinnium" might also be a blend of "Entropy" and "Echinium." "Echinium" is a name inspired by the genus "Echium," which includes flowers like the bluebells or pride of Madeira.
I hope this solves the mystery ^^
