Do you have a pic? My plant isn't big enough to propagate yet but it IS a cutting, as I think any PP plant would be. Doesn't seem like the kind of thing that would have enough volume (profit) to use lab methods.
Technically, my plant could be made into several plants at this point, but it's not of a size I would like to cut, if that makes sense. The store where I got it has a GIANT one, and in Jan I asked if I could buy a cutting and got the privilege of visiting "the back" where they'd already put many cuttings in pots.
In structure and habit, it's exactly like another one I have that I've propagated many times that just doesn't have spots on the leaves. Philos in general propagate easily, no hormones needed. PP on the right, NOID burgundy Philo on left. The plant on the left is several cuttings from another plant. (Huddled in the baby pool under a cover where I do repotting so they aren't drowning in all of the rain and water standing/flowing through the yard.)
The nodes are where roots form. Aerial root nubs are visible along this stem.
