You are so right! If only someone with that information would pass it along to HMF. As it stands now, HMF does not list any gardens that grow the rose or any nurseries that offer it for sale. The usual sources, such as Modern Roses, don't mention the dimensions of the plant.

If you have more information, please pass it along. HMF will be the better for it. In case you don't know, users contribute the most valuable information about the roses included here. HMF welcomes comments and contributions from gardeners.
