M longiflora isnt hardy for me and multiflora doesnt seem permanent in my one attempt but it does bloom first year from seeds. M longiflora tubers get huge and can be dug and stored bare in the garage--in fact I have to plant them out after I make a big sand pile for them to crawl around on. They dont need sand but it does make it easier to dig the tubers in fall. It also does sprawl quite a bit.

The percentage of viable seeds in multiflora is sometimes low, but since the seeds germinate within hours after the seed coat is nicked, and the seeds are soaked in warm water overnight, it’s not necessary to wait for any length of time to be disappointed.
