Cypripedium parviflorum x macranthos var. rebunense
S. Malmgreen 1999
Basically, Johnny Petersen is a somewhat unusual coloured Gisela. Instead of the standard form Cypripedium macranthos, the rarer white or yellow coloured variety rebunense was used for the cross. A speciality for advanced growers and not easy to propagate in the lab.
Height: 35-45 cm
Blooming time: May
