I absolutely adore this rose. I first obtained 'Lillian Gibson' in 2005 from Suzy Verrier's North Creek Farm in Phippsburg, Maine. From that one rose, twenty years later I have probably over a dozen plants. It doesn't sucker like a gallica, but if you dig it up to move it, and in the process leave a few roots behind, well you will have new roses sprouting up in that spot in no time! I've found the North Creek Farm catalog description of 'Lillian Gibson' to be spot-on: "star of the garden"; "the very finest of the hardy climbers" with "beautiful semi-double cupped blossoms of clear, soft salmon pink -- over a very, very long period of bloom but technically non-repeat. Very healthy, bright green foliage and nearly thornless red canes."
This cultivar is listed as diploid in the paper 'Pollen diameter and guard cell length as predictors of ploidy in diverse rose cultivars, species, and breeding lines'
