I don't know why these roses are growing either though I wonder if some are treated with something that stops them from growing. Perhaps you got roses that had been treated with fewer chemicals. Anyhow, I hope your babies grow strong and well! Wish I could supply you with my organic roses during your pregnancy! Of course that would have to be next spring now and suspect your babies will be due before then. I hope you will keep us informed of how your little gardeners are doing. What a wild adventure you are started on!

be patient and continue caring for it like your other roses and it should do fine it takes mine about 2 years to grow into nice size bushes.

It's better planted outside than inside for sure even at this late date. I don't know where you are so I don't know when your first frost date is but in my zone 6 it's usually not until mid October or later. That would give it a good 6 weeks to get established and I think you'd be OK. Dig a big deep hole. You want to plant it a little deeper than it is in the pot now. When you take it out of the pot try to keep the root ball intact as much as possible. The less you disturb the roots the better. After it goes completely dormant you can winter protect it by either mounding up with soil around the plant or with some kind of mulch. Leaves will work fine. Since it's a mini you can pretty much bury it in leaves but put a stake there so you'll know where it is come spring. And if you get a lot of snow it's OK to pile it on. Snow is a very good insulator and will protect and hydrate the rose all winter. In the spring when the ground thaws and night time temps stay consistently above freezing (that's April here but may be different for you) you can start to uncover it gradually. Once you start to see some new growth uncover it completely. Prune off any dead wood and she should give you a summer of lovely blooms!

Not only are there multiple cuttings per pot (sometimes up to five), but multiple varieties are substituted for each name. What you find in April as "Red Kordana" (or whatever other name the specific producer calls the rose) isn't necessarily what you will find as "Red Kordana" a month later. The names are trademarked and the outlet simply orders them by quantity and color, or as a quantity of mixed colors. Whatever the company which owns the patents substitutes for that color at that order time has ready is what the retailer receives. From a marketing standpoint, it's great. From yours, perhaps not so much. If the one you found is ideal for whatever use you have for it, you may, or may not, be able to find it again. That was one of Ralph Moore's huge complaints about how the mini market was changing before his death. He believed in creating a specific good rose and offering that rose under its name. Not in making a name and offering a dozen different "disposable" roses under that name. Your rose may remain healthier due to not being as crowded, or it may return to the black spot issues. Only time will tell. Many of these grocery store minis will perform outdoors, but not all. They weren't bred nor selected for garden use, so finding one which doesn't either become a "Jack and the Beanstalk" plant with small flowers; a diseased mess; or one which won't grow or flower in less than greenhouse conditions, is likely to be a hit and miss proposition. My youngest sister filled her front yard with those nearly twenty years ago. They receive virtually no care, pruning, fertilizing, etc., and they have lived and produce flowers. Hers aren't "pretty plants" but they fill volume, occupy space and require nothing of her other than the sprinkler irrigation they receive.
