Just a pipedream at this point, but will have some space to grow pretty soon... got a couple n00b questions.
Wondering if a rhizome is needed to get started, or can you start with a clipping? These will be purely decorative. Thinking of having a 2nd story deck planter running them down to the 1st story. Figured gravity would do it's thing... is twine necessary?
Need a rhizome, which is a root cutting. So if you know someone who has a good root structure developed, they can make you a rhizome.
I have a couple growing in pots, and they are doing very well. One didn't survive the winter, but I left them out the whole season (and we're in Minnesota). Get a big pot, as the roots need a lot of space.
The bines want to go up, so twine is good. I would start them on the 1st story, and run your twine up to the 2nd story. The bines die every year, so it's nice to be able to cut down the twine. The roots are a perennial, but the bines are annual.
