I have 3 pots of Geraniums that we took out of ground last fall. We put them in a unheated attached garage that does not get below 35 degrees. they were on a shelf with no light(no windows)
They continued to stay green ( however a much paler green.)
Is there a chance that if I put them back outside this spring that they will flower again?

They should flower again. Introduce them back into the sun slowly.

Daisy is quite right about introducing them to sunlight gradually. I have some that were overwintered in a well lit area, and even they are having to be introduced to the great out doors again quite slowly. I put a couple out in what I thought was a fairly sheltered area, and they got very droopy looking when the sun found it's way onto them.
