Petunia Growing Information and PhotosPeople routinely claim that petunias are annuals, as if they completely drop dead once September rolls around. However, I have had MANY petunia plants last through the winter and the next summer, as long as I bring them inside. I'm in Massachusetts, so they'd turn into crispy ice cubes if I left them out. Instead I bring them in, and they even flower in the winter.
Petunias originally hail from South America, and intriguingly they're a relative of the tomato! They were only brought to Europe in the early 1800s. So this wouldn't have been a plant that the medieval English nor the Renaissance dandies would have known about.
I use my petunias in hanging baskets. In the summertime they go out on shepherd's crooks and decorate my back porch. The hummingbirds love them. I "dead-head" any dying flowers by pinching off the whole bud area (not just removing the flower part). Then, when it gets chilly, I bring them in.
Here's a photo of my petunia in January 2013, making a fresh flower. It's the first flower of the winter. So yes, during much of the winter they are simply green foliage, but that is fine with me :).
Then it burst into life in the spring! These photos are from April 2013.
