when is a sweet pea not a sweet pea?

I sowed  5 different packets of sweet peas, dotted around the garden. One packet looks like it was some sort of vetch. Should I pull it up or leave it? It is entwined around the normal sweet peas. Have I caused an infestation or is it safe?

    It looks more like a perennial one.

    Many people have had problems with vetch seeds being mixed with the sweet peas, so it’s probably that.

    it's a vetch. Others have had the same thing this year

    Yes, I thought as much. Thank you for confirming.

    The seeds are so similar

    if you think it's pretty, just leave it. It's doing no harm

    I've just read that vetch is invasive, and can take 5 years to eradicate because it spreads via rhizomes.
    I think I'll keep the ones in pots but dispatch the ones in the main bed.
    They are pretty but there are plenty of proper sweet peas. Thank you all for your help.
