I'm from north of Toronto as well. They can get up to 3 feet. They flower during summer for about a month or so.. They are so very easily propagated and I got mine by snipping off a couple of stems from downtown parkette.

Hi Ianna, thank you for the reply.
Can you please tell me how do you propagate the stems?
And are they from old grow or new grow stems?
And also what time of the year did you do that?

Thanks

I used soft stems (green wood) cuttings. Removed the tip and left only 2 leaves on a 6 inch cutting. I sunk the bottom with leaf nodes in a pot of soilless mix, topped with a plastic cover. It was around summer since I took the cuttings when the plants were just about done flowering. Didn't need to use rooting hormones but if you feel you need them, do get the appropriate type for greenwood.

They grow from both new and old wood. Old wood just takes a longer time to propagate than say green or semi green wood.
