A Fascinating Plant: Update 3

To read the original story about this indoor sweet potato plant and to see the updates (Update #1 and Update #2) click on the links.

In Update 2, I shared how the plant was sending out so many shoots that I had put up a trellis to support them in going up rather than taking over the dining room floor. Since then they have continued to grow. A few of the lower leaves have begun to wilt. These photos were taken on December 6th.

And the ones below were taken December 13. Notice in the last photo that some of the leaves near the pot have dried and fallen off.

One of the shoots has grown about 15 inches since November 28 when I put the trellis up. Between December 6th and December 13 it grew 4.5 inches. Since then it has grown another 3.5 inches. In fact, you can see a difference between how it looked this morning and how it looks this afternoon. It has almost reached the top of the trellis!

I wonder if the plant is likely to produce sweet potatoes. Does anyone know?
