This 'Rabbiteye' blueberry was the victim of a wayward lawn tractor 4 years ago. When were were digging the hole for its replacement, I found the chopped off base and it appeared to be alive. The mower had chopped it artfully, so it went into a bonsai pot. (There are 8 other plants out there, and we have picked several gallons of blueberries this summer. I'm actually getting a little tired of blueberry cobbler. Just a little, though. Most will be frozen for cobbler in December.)
There is a LOT of work yet to do, but here is the little plant 4 years later.
