Zuzu ...
When I talked with Kim about Ludwigs the other day, he told me that the roses would not be bands, but would be container roses. The roses are going to be produced in Canada, but distributed out of Arizona.
As for the measurements, I think it has to do with the metric measurement system vs the US measurement system. The heights they are using are probably what they see in South Africa which is similar to Socal. They are probably over-stated for more northern gardens.
To me, the interesting thing is that they may be carrying a lot of roses that have never been available in the US or are no longer in commerce in the US.
No one has any info about the quality of the plants.
