That low T is enough to bloom charlesworthiis indoors for me.Hmm. Not sure what you mean? I don’t grow my slippers outside. But I don’t turn on my indoor heat until outdoor temps fall below 33.
Lowest indoor temps to which charlies have been subjected would be between 45 Fand 55 F, cool fall nights. They had some weeks of this coolness. They have it every year. Everybody gets to get cold in that front window.
