Several months ago, my family and I visited a local garden shop and bought a number of succulents. My son found a small piece of a succulent on the ground and brought it home with him. We potted it, and it has grown substantially (see picture). The problem is that it has grown a very long and thin stem such that it falls over without support. I do not know the plant's species but doubt that this growth is normal. I cannot believe the elongation is due to light deprivation. The succulent is placed by a south facing window that gets the most light in our home. We have many other plants, including other cacti and succulents, situated by the window, and these have not been experiencing any growth-related problems.
Can anyone identify what the problem might be? My only other thought is that the clipping came from a branch and that it will continue to grow as a branch (long and thin) rather than replicate the main form of the plant it came from.
