So, how do we know for certain which scientific name is the correct one? The ATP database entry shows it as Kleinia petraea and lists Senecio jacobensii as the synonym:
Trailing Jade (Kleinia petraea)
When I google I find most places show the name as Senecio jacobensii but a few list it as Kleinia with Senecio being the synonym.
I will go ahead and add my photo's to the database at the Kleinia petraea location and hopefully someone will be able to figure it out for sure at some point because it's really confusing to me.
