Super Glue to the Rescue!

[Tess]

I have this cute houseplant I got recently as a gift. Not sure what type it is. Half of one of its biggest leaves broke off clean, so my son super glued it back on for me! This is a few weeks after the procedure and the plant is thriving - including that leaf!

Most interesting. Perhaps the glue held the tissues in place well enough to create a 'leaf graft', if that is what to call such a rarely performed procedure. This would likely work best on thickened or succulent leaves, such as those of your Kalanchoe blossfeldiana cultivar.
