Yes, that's correct, but he did mention 'Goethe' in the GST 'Rose Book'
" A rather unsuccessful merging of two dissimilar parents, R. multiflora and a moss rose. Very vigorous, excessively prickly with much bristly brownish-green moss. Panicles of flowers are born freely; they are small semi-double or nearly single, light crimson to pink, with some scent. 5 feet"
I am intrigued: where does he say that? The "Rose Book" is a compendium of his two books on Shrub roses plus "Climbing Roses Old and New" and I could not find a mention in any of These.
Those two are on p. 187 of "Old Shrub Roses" and there is nothing in between. It seems GST did not just add the 3 books, but revised the text. I will have to get the "Rose Book" too.
Thomas, Graham Stuart. The Graham Stuart Thomas Rose Book. Portland, Or.: Sagapress/Timber, 1994.
The ISBN is 0881922803. A note in the bibliographic record states, "Comprising The old shrub roses. Shrub roses of today. Climbing roses old and new; enlarged and thoroughly revised." The last statement suggests GST not only compiled three books but added material.
