How tall is it ?

I didn't know what "hannaford" was, but coincidentally, it was mentioned in an article in yesterday's NY Times about supermarkets.

The mini is probably one hybridized by Poulsen Rosen, from the Poulsen Parade series of miniature roses.
The plants were grown indoors, in greenhouses. They are own root. Although typically sold as "throw away gift" plants, they can (and should) be grown outdoors.

well when i posted this message it was only about 8 inches tall. NOW its about 15 inches growing like a weed!!!! and ty diane nj. ive noticed lately that the supermarkets carry alot of the "parade" variety's :)

I actually had the same one, it didn't survive our move. I got it at the supermarket. Mine was not tagged with a name, don't recall if I ID'd it at the parade site or not. My computer went down in March, haven't gotten it running yet

Since you are in NH you might want to make sure you winter protect it.
