Yes, Peaches and Cream!! Check out DG under 'other details' it says suitable for growing indoors. LOL. It does not surprise me because they often have weird data.
I bought a tree for my back yard based on their data of 15-20 feet and it was wrong, it gets 40 feet tall and it is too big for me to dig up at this point. I reported it last year, their own vendors even had it listed as 40 feet but no one bothered to verify the data, they just leave it there till someone, like me disputes it. I do not have time for that. I look every thing up at 4 places now and I do not dispute anything. If their data is wrong it will stay wrong. For one thing I can not click on edit like here, so I do change stuff here if I find it is wrong and one of the administrators will verify every single thing I do or change, as it should be.
Thanks for the information about the clumps, I did not know anything could grow it self to death, what kind of food do the tubers like anyway?? Bone-meal??
