Answer: Since this plant is only considered to be hardy to zone 8 and your zip code places you in zone 6B which is significantly colder than that, I do not think you will find it offered as a landscape plant in your local area. It is sometimes propagated by seed and sometimes suckers (from the base of the plant) are divided off and transplanted in the spring. You might find it as a houseplant however. I'm sorry I can't be more specific for you but I hope this helps.
