That's a cultivar of Hibiscus acetosella. Should have beautiful pink flowers in the fall, but it's mostly grown for its foliage. It's one of he edible hibiscus, with the leaves and flowers being edible. It puts out lots of seeds and can get a little invasive if left to its own devices. If you cut that one back by half, it will branch out into a bushier shape. Then just strip all the leaves except the top few off the part you cut off, stick it into rooting hormone and into a pot -- or just in the ground. They root easily.

Don't eat too much of the leaves. They contain oxalic acid crystals.

What a nice name! Leaves are very sour for sure - but that looks very much like the generic H. acetosella I grew from seed from Pinetree Garden Seed....?

Still have plenty of it around because it reseeds easily.

I picked one up from a vendor at the Wings and Wildflowers last weekend. He had it labeled Maple Leaf Hibiscus, but I recognized it as Cranberry Hibiscus. The I like the flavor of the tender, younger leaves more than the older ones, but I have heard that the flowers are where the real flavor is. Still, I think they would work better as an addition to a salad.

I wasn't aware that it reseeds, but it supposedly roots from cuttings easily enough as well. I will have to keep an eye out for reseeds so it doesn't cause a problem. I have read that they get 3-5 ft tall, but one of the presenters od Gardening Australia had a stand of them that looked easily 10ft tall.

Iam laughing here thinking.... iam not eating my plant!... But maybe I will get curious and want to sneak a nibble, my luck my hubby with catch me licking the plant... Lol

The seedlings are easy to pull
