I can’t offer any pansies for your search but I can offer solidarity, lol. Tracking down common flowers (specifically yellow ones I feel like??) can be so tough. Finding the right yellow rose was a hassle, hopefully your pansy search is easier!!
Hey (since the thread got locked), I just wanted to add, not to sound rude or anything, but to correct you, I think you mean breathing in your own carbon dioxide-carbon monoxide is actually quite dangerous and deadly.
Thank you for letting me know!
