Hm, well, I heard they give off oxygen in the day but take in oxygen at night, which is why some advise not having plants in the bedroom, robbing your O2 while you sleep.
As for getting pelargonium to grow, they are like weeds. Just stick a bit in the ground and ignore (they don't like to be watered or fussed at), and they will grow into a new plant (another orangy-red legacy from the previous owners of our house, yuck, but they do smell great).
And Snowwark, yes, the original quote was "savage breast":
AUTHOR: William Congreve (16701729)
QUOTATION: Music hath charms to soothe the savage breast,
To soften rocks, or bend a knotted oak.
