You may have been very lucky!

I have never heard of P. edulis being propagated that way, and it has
never formed such roots on my plants. It sounds more like P. alkekengi
(also called P. francheti) the one that is commonly grown for decoration,
which is propagated like that and can become a pest. Some reports are
that it is edible, and others that it is significantly poisonous.

I believe that it is now called P. peruviana, but I have also seen
references which had two species, called P. edulis and P. peruviana.
So what else is new?
