I have had a yucca plant for about a year now, that has gone through some tough times: it moved, then it suffered some cat bites, then a bug infestation. When the last thing happened to it, I moved it outside, since it was May. I carefully transplanted it, washing it's roots even more carefully, and it's lived through all of this trauma and is thriving again.

Now on to my real question. When I got the plant, there were two different plants growing from it. Does that make sense? Two stalks, I guess I mean. In May I realized that the plant had produced a small offshoot, and when I removed it was when I discovered the bugs. The smaller of the two original stalks did not survive. (The bugs were those millipede looking hairy things that we get a lot in the humid northeast, I'm not sure what they are.)

Now I have the larger plant and the offshoot planted separately. However, recently I got to wondering about yucca reproduction, and wondered how it produced the offshoot, if it needs a partner to produce another offshoot, and if I should put the offshoot back with the larger plant.* I would love it if the plant produced more offshoots!
None of my container gardening books have any information on this, all they say is that the plant "may produce offshoots."

Thanks :)
