Pineapple Express auto - post harvest re-grow!

Harvested my Pineapple express about a month ago.
Left the stump outside with a tiny bit of green left on it and it started growing new buds but with weird leaves!
Anyone seen this before?
Would you smoke it!?
Looks pretty frosty & smells good!

its just foxtailing from running so long ..... let it go longer and it may throw nanners

"foxtailing", that's a new one for me
thanks for the info

Cool, I have never seen that, I can see the pistols but what is up with those leaves? I guess you found a plant that keeps on giving, I have pineapple express but have not yet tried to grow it, I'm about to chop some bubblegum I'll leave a bit of green and try and duplicate your results under lights.
