They seemed to grow rather slowly in my garden. The seed packet said 2
months, but they were still far from grown at that time. I think I've
been letting them grow for well over 4 months now, maybe 5 or 6 months.
I think some of them are 4 inches in diameter now. The leaves are still
green and healthy looking. I'm just wondering, what if I just kept
letting them grow indefinitely? How big could they get?
