Calibrachoa is a tender South American perennial. You could think of it as a tomato plant.

With little stress -- undo summer heat and dryness and extreme winter cold -- it'll peter out much as a true annual.

But with comfortable summers and not-overly-frosty winters, it will continue for more than a year, much as it does in its South American home.

I have friends who've kept Calibrachoas three years. Up until last winter, that is.

I have a peach one and a white one, both in large containers with other plants and they even went right through last winter. This is their 4th year.
They look ugly in winter, but I just prune them back in spring and fertilize them.
My peach one died about a month ago, but I think I may have overwatered it.

If yours has stopped blooming, you might want to give it some fertilizer. I gave mine MaxSea once or twice a month.

Thank you Joe and Wanda. I'm going to try to overwinter them. Speaking of which, I have a coleus that survived outside last winter (in spite of three straight days of freezing weather) and this year it's a giant!
