P. ‘Clear Sky’ x P. ‘Constance Eliott’
Fischer & Diez Spain 2003
Min -2°C 28°F
A polyploid cross between P. ‘Clear Sky’ × P. ‘Constance Eliott’ by Roland Fischer (Germany) and Francisco J. Diez (Spain). Passiflora ‘Sonia’ is named after the wife of Francisco Diez. Based on the parentage and absence of pollen, it is believed to be a triploid. As you would expect the flower is very similar to P. ‘Clear Sky, but the fact that triploid cross can be done at all is of considerable interest.
