Ok, here are the pics. These were taken about a month ago and all have grown since then, but it gives you the idea.
The first pic is a new growth just emerging from the side of an old one. The side of the old stem seemed to split open to reveal this emerging growth.
The second shows a similar new growth that had progressed further. Both of these now have leaves which are curled into a tube. From my MILs (which was ahead of mine on growth) I think these leaves will get much biger than the tiny ones on the growth from under the ground before, before they uncurl.
My final pic is of the growth coming out of the soil from mine. I forgot to say above, that I repotted mine and could see the stems growing under the soil starting from somewhere connected to the old growths.
Finally, mine as a healthy plant seemed to do nothing for a long while, and I was really starting to think it would just sit there doing nothing, when it finally started these growths.
