You can keep it if you move it away from your other girls. I grew one out and harvested a few weeks ago it was great and I'll bet I didn't get but 4 or 5 doz. seeds. Of course I should point out that I tried to pluck all those little footballs off before they opened, naturally I missed a few and thats where I got the seeds. I got about 2.5 oz. off of the little tranny. Just my 2 cents
