no, they won't, they're freaks of nature, they last maybe 3 days. And they need exactly the right weather and temperature. So you're lucky.
You took fantastic pix of 'em too, so that's lovely,

Try comfrey or seaweed if they need feeding.
Or just pot them up (in bigger pots) in fresh fertile compost and water well.
