That surely is the largest Pony Tail I have ever seen. I used to have one that weighed over 50 lbs. but it was a midget compared to that whopper. That plant is in full sun. I have two small ones that I grow in bright shade. Can I acclimate mine to full sun? I guess the downside is that the Pony Tails may suffer when they have to brought back inside in the fall, though I could grow them in one of the greenhouses if I had to. I like to grow my two on the porch so that they can be enjoyed more.
