This is a comparison of two Phragmipedium hybrids, Fritz Schomburg and Yoko W. Fischer. They have not bloomed for me at the same time over the last four years, but the pictures were both taken this year under almost identical lighting conditions with the same camera/settings.
This first picture is Fritz Schomburg (besseae ‘Rob’s Choice’ x kovachii ‘Tessoro Morado’) made by Orchids Limited. The horizontal natural spread of the flower is about 12 cm:
The second picture is Orchid Limited’s Yoko W. Fischer (Peruflora’s Cirila Alca x besseae ‘Rob’s Choice’), also with a horizontal natural spread of about 12 cm:
Peruflora’s Cirila Alca is (kovachii x dalessandroi) and it was registered the same year that Fritz Schomburg was registered (2007). There is chronic debate about whether dalessandroi should be a separate species, a var. of besseae, or just part of the natural variation of besseae but Kew still considers it separate for breeding purposes.
Phrag. besseae ‘Rob’s Choice’ is a strong presence in these two hybrids. It is a polyploid plant that strongly influences size, shape, and coloration of its progeny. Here is an old Orchid’s Limited photo showing the size of ‘Rob’s Choice’ and a comparison with a diploid besseae.
I think that Fritz Schomburg and Yoko W. Fischer made with a diploid besseae are more influenced by the kovachii parent and often larger, but at the expense of the full and round shape.
