how cold can a room be for angel begonia to survive
I have some beautiful angel and devil begonias that have done well outside and moved them into my unheated room to the south and west. Does it have to be "warm" for them?
It doesn't have to be warm, but the temp should stay above 45F. Begonias are tropical plants. Here's a resource you might find interesting: https://www.gardeningknowhow.com/ornamental/flowers/begonia/
