Purple moby dick

I would have to agree with everyone who posted before me. Nothing to worry about. It's just the odd seed. I wouldn't germinate any seeds its produced though cos your going to have a 50/50 chance on it being male, and a greater chance of it going hermie

Btw, I'm reluctant to tell you to squeeze that to feel what it is (coz there's a chance it might have pollen nearby that you could disturb)...but if you're not concerned about that seed entirely maturing, cut that off and check if it's a seed, somewhere else (and also if there are some nanner looking things near where it was).

Yeah looks like a seed. If you can, take some better photos with close ups of flowers, I might be able to spot stealth nanners.
