I'm brain dead this a.m. Propate is shortspeak for propagate. Sorry

Sedum 'Matrona' can be propagated via the stems and the leaves...but...

What I would do is remove all of the leaves on one side of the stem and lay that bare side in the soil...leaving the "good" side at soil level, but not covered. Tuck it in a bit, water it gently so the the soil will keep it in place...you might even place a piece of wire over it to keep it still...

Then, just wait...it will eventually grow into a very lovely clump...
