How do I propagate a Solanum rantonnetii?

I have this beautiful bushy plant with purple flowers. Im pretty sure its a Solanum rantonnetii or a blue potato bush.

I would like to have more of them around my house. How do I do this? Do I take cuttings? Or do I have to buy another one from the store?

Thanks for your advice!!!

Also known as deadly nightshade, why you'd want a poisonous plant in your yard i don't know, keep the kids away

Try tip cuttings or seed if you can gather it, shouldn't be too hard from cuttings
