In my bamboo hedge (yes, I know. It came with the house), there was a twining vine which I always unthinkingly ripped out when I saw it getting too frisky. I just assumed it was a morning glory, so I never looked at it too closely.
But the other day, there were round-oval, slightly ribbed seed pods on the vine, about 3 to 4cm in diameter: so, not a morning glory after all. So I've kept an eye on it and yesterday took the attached 3 photos. It's lovely: a dark red-purple, vase-shaped flower, like an orchid or one of the carnivorous plants, heart-shaped leaves. Stupidly, I didn't take photos of the seed pods.
Can anyone identify it?
