What you can do is dig up the taproot and use that to plant in a indoor pot under lights it will grow leaves it can also be baked in the oven and ground up as a coffee substitute
But in this day and age its dangerous to dig up plants just anywhere because of weed killer and other things I would be wary on it just my opinion
Dandilons are great fun with many many uses not just greens but be careful with wild foods some types have dangerous look alikes or are weeds which means they could have been sprayed I would buy seed of Dandilons and plant them indoors belivie it or not they do sell seed of Dandilons
