References: Sisley-Vandael, catalogue 1937, p. 6: Van Houtte, catalogue 1842, and following; Verdier, catalogue 1843, p. 10. Commerce: not. Collections: author, Gap-Charance, L'Haÿ.
The first mention of this variety is in the catalogue of Sisley-Vandael of 1837 which announces it as "pink". This nurseryman was specialised in imports from the Netherlands and Belgium, is this variety originating from there? All the old catalogues describe it "pink" without ever adding "with paler edges": it is very surprising that this characteristic is evident on the specimen at L'Haÿ.
