Can anyone identify this
I am hoping that someone will be able to identify this plant. I noticed it growing in an old tarmac driveways that is now more like a gravel bed. I transplanted it into an old breezeblock and its really taken off. I am no gardening expert and have no idea if its a plant or a weed. It looks nice and is thriving so eitherway it gets to keep its new home.
Any help would be appreciated. Many thanks.
