I’m near Philadelphia, PA and need more information about your edible plants besides lettuces that are happy at lower temperatures.
I get very little sun and know from experience that plants like basil, etc. will not even germinate on my windowsills much less grow in colder weather. So I want to work with what I do have.
My green lettuce planted on October 28 is growing well—in between my kitchen and living room—with 3 more pods and 6 romaine waiting for space in my gardens.
The windowsill temp in my coldest room—which is the only space left—dropped to 64° F last night and will drop lower in the really colder months, but certainly not as low as in Toronto, Canada.
So what edible leafy plants besides the two lettuces would be good on a northern climate windowsill in cold weather? And just how low a temperature can they germinate at and tolerate?
