I live by Peoria, IL and these minis survived -22F temps for a week this past January. I only had oak mulch at their feet and oak leaves that blew in as winter protection.

Dan Keil grows a large numbers of minis and mini-floras and posts here on GW; he lives in Zone 5 also. You can e-mail him also for a list; he is the Consulting Rosarian for our area and would be glad to help you.

Thanks so much!! my list is started! I know that busy bee does just fine as does a few others, but wanted to hear from others who have some miniatures. Bought a bunch from noreast and am waiting for them, wanted to know which ones need extra winter protection. Will contact Dan Keil, and thanks again! Deb

I've grown hundreds of miniatures this past decade or two - too many to list. It got below -20 F this past winter.
I've found that roses from certain hybridizers tend to be hardier than others. And the really old micro miniatures like Tom Thumb and Cinderella are incredibly hardy.
Anything by Harm Saville is winter hardy - that was important to the Savilles. Wendy White's roses have all proved hardy for me. The roses I have that are Frank Benardella's are also hardy.
But I also have quite a few individual miniature varieties from other hybridizers that have proved quite winter hardy. Pucker Up is quite the monster. Jean Kenneally has proved wonderfully hardy, as well as producing an abundance of nearly perfect blooms.
Post your list and I'll see if I have any of the same ones.

Hi, thanks for the reply -- here is my list of the roses I've ordered (it's a lot!!). Asked the question because I noticed after I ordered them that some say zone 6. I'd like to keep them in the ground if possible, with mulch, etc. Any help on any of these -- how to help them, will be appreciated. Thanks!

Thanks -- if you have any that are less winter hardy than others and need more protection -- let me know (and also, what do you do -- extra mulch?) We also get -20 degree weather on a pretty regular basis!!

I've had some of those for a long time.
Cinderella and Sweet Fairy are very very hardy.
Others from your list I've had for years are Chasin Rainbows, Live Wire, Overnight Scentsation, Pacesetter, Ralph�s Creeper, Red Minimo, Sachet, Scentsational, Irresistible, Mary Marshall, Minnie Pearl, Rose Gilardi, Starina, SunnyDay, Toy Clown, Denver's Dream, Jean Keneally and Jeanne Lajoie.
I could never get Ring of Fire to survive the winter, and I tried several times.
FWIW, I rarely have snow cover in the winter. I've gotten some pretty tender stuff through the winter by putting a foot of maple leaves (they don't matt) on top of the plant. Also, some things have done well by being on the south side of my brick house where stays considerably warmer.

Thanks so much... well, I'll look into doing something w/ Ring of Fire. Bring it in? put in a pot, store in the garage?? I'll figure it out. I thought of maybe putting it in a pot, overwintering in a garage,, but beforehand getting a cutting from it, just in case it doesn't make it...

and good idea w/ the maple leaf mulch! I thought of getting chicken wire and making a cage around the rose (the ones that are more tender...) and piling up the mulch. The purpose of the cage would be to ensure that the mulch stays put.

X-Rated may also need some extra care. For several years I felt it was very hardy - a big, robust bush. However, a couple of years ago I almost lost it over the winter even though it had a mound of chopped oak leaves on it. Fortunately one cane came through and it is now rebuilding itself, but apparently it can have problems under the right winter conditions.

I have around 200 minis and mini flora roses in my yard out of the 400 roses I have. I have been growing minis for years. They are on their own roots so they are hardy. I do not cover mine at all during the winter. Just make sure the plants are not dry going into winter.

thanks for the info!! we'll see how mine do over the winter. Deb
