I'm airing my ignorance here, but has anyone grown Fabvier and White Pearl in Red Dragon's Mouth side by side? Given that the one of earliest references for Fabvier mentions a full, domed, once-blooming pink rose, I'm wondering if a mixup occurred soon after.
I think you may be right Margaret. Both bloom in flushes, so that early reference to 'Fabvier' being once blooming is intriguing. The name 'White Pearl in Red Dragon's Mouth' does sound more like 'Fabvier', but then a pearl is fairly tiny so it may relate to the way the white circle is hidden within the "dragon's mouth" (i.e. red petals)?? Even so, I am at a loss to know how to tell 'White Pearl in Red Dragon's Mouth' from 'Cramoisi Superieur'!!
