Does your Mom own the house? If so, she could lose it! The cops have a nasty habit of seizing property- it's all $$$ in their collective pockets. Does she rent? She could be evicted without notice! Ever been homeless? If she had left them, she would have been contributing to the delinquency of a minor and more! You obviously didn't stick them in the "back 40" of your yard- she found them. Mom's flower garden- not the brightest place to put them- try going for a "picnic" in the woods next growing season.

I will give you some semi-good news. Usually, the taller seedlings are males. Now I'd suggest that you start looking for an alternate growing site, cause she'll pull the rest as soon as she spots them. - Granny:hippy:
