Hi, have you grown or seen Princesse Louise ? I was reading about it while hoping to identify a found rose. The 1836 reference seems to include it in the 'Autumnal Flowering Roses' and I was wondering if anyone noticed some reblooming.
I think this file may perhaps be merged with the 'Princesse Louise' (H. Sempervirens, Jacques, 1829) One of the nurseries listed are carrying that earlier rose and I can find no reference to an 1868 rambler.
