The website says: "Ludwig’s Roses, est. 1971, is the largest container-grown-rose nursery." They're grafted roses, so they'll be too big for bands. They'll be growing in larger containers, but I don't know whether they'll be shipped in those containers. It'll be interesting to find out.
The descriptions are vague, but maybe they'll be fleshed out. The height descriptions make me laugh: "above head height," "hip height," "shoulder height," etc. Whose shoulder? Whose hip? Your shoulder's more than a foot higher than mine JD, so that's vague in the extreme.
