Thank you! I thought it was C. virginiana, but one of the women at the swap where I got it said it was C.flammula. I am happy to have you confirm it.

I was able to get two small plants today so please disregard my post. Mike

I overwinter stuff in pots every year. There always seems to be a "pot ghetto" hanging around. Last November, I bought 55 plants at a local nursery on sale for $3-5 each! Some were in small pots, but most were 1-3 gallon pots. Most of them were native perennials and grasses. No chance of something like warm season grasses growing and establishing roots that late in the season! So I planted a few cool season grasses, then sunk most of them in the ground in their pots. I put some on the north side of the garage, surrounded by a heavy mulch of leaves and also bags of leaves. This is what I do with the pot ghetto every year. The idea is to insulate the plants from temperature extremes. We had persistent snow cover all winter last year, which helped to protect all these plants in pots. I didn't lose anything but some Scabiosa columbaria 'Pink Myst' - which is not a native and is notorious for dying over the winter anyway, even when established in the ground.

Sue, if you want to add that info to your profile so that it shows automatically by your name, here's how: Go to Your Houzz in the upper right of every page, click Edit Profile, and on the left side click advanced settings. Well down the advanced settings page is a blank labeled Climate Zone for Garden Forums along with a link to find your zone. If you add info on your state or the nearest large city you will get even better information since zone only relates to average coldest winter temperatures. Then return to the top of the page and click Done Editing.
