Found this Lily bulb root that has grown its own roots. No stem piece of bub nothing but a piece of Lily bulb root where I dug the bed up last year. Y'all ever seen that happen? Will it eventually grow a plant?

Duane - my 'guess' - and I'm not a botanist by any means - is that there were probably enough nutrients, sugars, starches, etc. in the main root for it to keep growing some after it became severed from the bulb. But it won't keep growing like this (I think you dug your lilies 6 weeks or so ago?) and it will eventually rot. For it to produce a new bulb there needs to be a piece of the basal plate still attached, just like you have when producing new bulbs from scales. Hope this helps.

Substantial roots of most plants may easily stay alive for 3 months even during the growing season and more so during dormant periods, when conditions are right. I am not surprised. It is exactly this reason why some prefer kill virused lilies in specific situations with chemicals rather than digging them out.
