I recently purchased a Sempervivum Tederheid plant, and seemingly overnight, it has sprouted a long tall stalk out of the middle. (similar to the plants on the left side of the picture to the left of the Mamajack's CoOp picture. Can anyone give me some insight as to care for this? Should I be trimming it back and replanting the taller portion? I can't seem to find a good answer anywhere online, so any suggestions would be greatly appreciated. Thanks in advance!
Best,
Lindsay
