Greetings, I've got a single stem garden phlox, sapinaria officionalis. It's come back each spring for 3 years but has not multiplied. There was still only a single stem last summer.
Any ideas how to propagate this plant? Thanks!

Dan, Why would you want to propagate a poisonous weed? Ah, building a playground, are we? Any how Saponaria officionalis has a hollow stem so cuttings won't work. You could pinch off the new growth and force branching or you could dig the plant up and try to divide the rhizomes. I would wear gloves. Pretty flower, by the way, looks like Pinwheel Jasmine (T. divaricata) that we have in zone 10.
Searching on "saponaria propagation" (note spelling) on Google produced
1,400 links. You might try the same.--beeky

Thanks for the spelling correction! I did some searching and found many sites that listed sapinaria officionalis as soapwort and a few other common names but none called it phlox so...... I searched for gargen phlox nicky and found many hits with pictures.
(We also have soapwort and it propagates itself just fine!! In fact it's invasive so we've put a root barrier around it to keep it in check.)
Obviously the label that came with the plant was wrong. What I have apparently is Phlox paniculata 'Nicky' Summer Garden Phlox and I'm still searching for ways to multiply this fragrant flower!
Thanks again! Peace!! Dan D. Louisville KY good ole USA
What did you use as a root barrier?

Cuttings should work.
root cuttings and division in spring seem to be the recommended method.
