William Robinson's 1912 book, 'The Virgin's Bower' writes "it's first introduction was in 1829... to the Botanic Garden at Ghent; but until 1836-38 it was not much known in French gardens. I have only seen this kind grown well in Miss Willmott's [of other horticultural fame] garden at Warley, who writes:- "I believe my plant is the only one in cultivation in England. I counted 500 flowers and seemed only to have made some way in reckoning up the total." " Magnus Johnson's research confirms that von Siebold introduced the form to the Botanical Garden in Ghent in 1829, noting that "on the same occasion [he] also brought C patens from Japan."
