all lettuces are pretty much identical to prickly lettuce. they revert back to the wild form if you leave them to grow feral for a few generations.

Fig trees seem to have a lot more latex than dandelions, I wonder why they don't use them to make rubber.

Woah, cool! Do you know if that’s true of like, brassicas and stuff? Like would broccoli become wild mustard? Just as an example, I know you don’t like brassica much.

And yeah hmm. I think the article said something about having to test the dandelion latex to see if would work—perhaps something about fig latex just isn’t amenable to rubber making.

I let my collards and kales self seed and they remain collards and kales generation after generation. They don't seem to readily cross pollinate with the wild mustards that grow nearby, but it is possible to hybridise them so I imagine they'd eventually revert to a wild form:
