What type of pea?

[7238SM]

Last year, this trough had climbing sweet peas, so when I saw 2 round seeds in autumn, I assumed they were sweet pea seeds. They sprouted over winter and now look like this. I have a pot of climbing sweet peas for comparison. Google lens says they're an edible pea, sweet pea or a perennial pea. What do you think they are?

I can’t see a picture

@PersephoneParlormaid Yes, the pic would help! 😜

To get a different type of pea, the seed would have to be a different species to the parent plant which just doesn't happen. They are Sweet peas.

Thank you. Yes, I realise they're likely sweet peas. They are just so much more fleshier/thicker than any sweet pea I've ever grown so thought there was a slim chance it might be one of the many other peas I grow. Maybe they are just so vigorous from the autumn start?
