Good for you on the no spray. Most minis won't survive in Florida without spray unless you grow them in pots. Don't know why the pots help but it does. In the ground I can grow Green Ice, and Apricot Twist.

Perhaps you could try some of the older polyanthas. I've found them to be very trouble-free over the years, many with complete neglect. There are so many varieties in all sizes and bud form, but I'm sure you know that. I'm just a newbie, but have maintained my original rose plantings for years. I''ve added a few more polys this year and intend to continue with that. We're VERY humid here in the summer, btw with a lot of rain.

There is some thought that because the minis tend to be smaller and the leaves are closer to the ground they are more susceptible to fungal diseases because the water splashes the dirt up on them more easily. I don't know if that's true or not. And I haven't found that growing them in pots makes them less susceptible either. They're still close to the soil in the pots. Minis are just not particularly disease resistant. I do have Softee in the ground and it does pretty well but is not spotless.

Bees Knees gets an excellent rating

Bred by Zary. For some reason it isn't patented. Ralph Moore was the Mini Hybridizer, but his climate wasn't appropriate for finding disease resistance. I think that most of the other hybridizers either had good climates for growing roses or were exhibitors who routinely sprayed their roses. And those Grocery Store Minis were designed to be grown in a greenhouse environment, and discarded after soon after purchase.

I have 27 minis and the only disease free one is Green Ice. Some are pretty good but most will completely defoliate without spraying. I just thought there might be some more out there as good as Green Ice.

Bees knees and Denver Dream are free of disease for me. As is green ice, and my lavender parade mini.

I was going to say Green Ice. Bees Knees defoliates if I don't spray it here in central NJ.

My favorite mini is 'sweet nothings'. It's disease resistant, purplish/mauve blooms, heat tolerant, flowers drop off and nicely scented.

Lupo is BS resistant for me, and is a vigorous, hardy plant. Such a pretty shrub. It's a big mini though; I need to find another spot, it's outgrowing my mini garden.

Lupo is recommended in the book: Roses Without Chemicals as well as these minis Flirt 2011, Oso Happy Petit Pink, and Roxy. I don't grow any of the latter so can't recommend, but the author got it right with Lupo.

Of course, disease resistant is a regional question. A perfect example is Denver's Dream - free of disease for ordphien, whereas mine completely defoliates from BS (even when sprayed!) Green Ice is pretty clean for me.

This mini

should be sufficiently disease resistant.

It also appears on the spreadsheet (at the top) linked here:

I have all the Vigorsa Kordes roses but they are all spreading ground cover roses. I'm hoping to find some that stay no bigger than 2x2. I want them for the front of beds I have HTs in. I may have to consider the idea of the Vigorsa roses though. Thanks for the reminder.

Newflora describes Roxy as "very compact mini" and "1x1".

I realize this doesn't mean it won't exceed 2x2. I remember the original KO was described as "3x3", and I've seen them 9x9.

A Felco #2 is always an option, especially when SternruBtau (hopefully I did the German justice) resistance is considered.

These might not be considered as minis in the strictest sense but I'll throw out a couple that work for me.

One is Gourmet Popcorn. I have it planted in dry rocky soil that was somewhat amended and it is the rose that is on the edge of the bed nearest the woods. It gets only several hours of sun a day. It is clean and blooming right now and I'm hard pressed to remember when it isn't. Kind of a "plain vanilla" little white rose but I like "plain vanilla". It has very few thorns.

Another is a Ping Lim rose called "Little Mischief". It reminds me in size and shape of a small polyantha. It's planted in a different bed but in a very similar situation. It blooms in cycles, covering itself with little red and white flowers. It's in full bloom now and, while not a show-stopper, is very attractive.

I assume you know about Sweet Chariot. Mine is a little bigger than 2 x 2 but could still be planted in front of a larger rose. Mine is planted in front of rose de rescht and it's a very nice combo.

I don't spray. I don't require my roses to be spotless but extreme defoliation means that it's a rose that can't stay here.

Thought I should add- For me "Little Mischief may need an asterisk. First summer, it just settled in and didn't change much. Second summer it put on new growth, but nothing remarkable. This year it seems to be pushing out, but not up. Some of the Ping Lim roses have a tendency to be "all about that base" and can get pretty wide. I'll let you know after the third year leap.

Paula Smart (aka Smart & Sassy) is new for me this year. Bought it because my few minis are all bad to blackspot & Chamblee's site shows this one as being very disease resistant and moderately fragrant. I see now that Kes posted on HMF a couple of weeks ago that it blackspots badly, though. If it's a blackspot magnet in E TN, probably will be in NE AL, too...but must be good somewhere for Chamblee's to list it as VERY resistant
