Yes, I do have an unheated garage, too.
I was wondering myself about starting in a warm house.
They would make for neat containers.
The garage might go below freezing if we have a cold snap, but I think those planted in the fall must experience freezing too?
I can get larger containers into, and out of, the garage easier than house too.
Great idea! I can WS some low annuals, or add petunias later.
Thanks to all of you:-- for helping me to think through my absurd purchase!
