I posted a picture of this same dahlia on Monday, September 18, 2017, so you’ll have to excuse the repetition. Although it’s not particularly large for a dahlia flower, it’s very pretty. Also, the plant has very dark purple, not-quite-black foliage. It’s lovely overall and we definitely need to dig up the tuber and try to keep it for next year. We’ve never actually done that before and I’m not sure how successful we’ll be. They are supposed to be stored in a damp place all winter in temperatures that are between 45°F and 50°F, which is a pretty narrow range and not something we have naturally in our house. Our basement is cool but not that cool and we do our best to make it dry, not humid (it’s currently at 38% relative humidity). So, we’ll see what we can do.
