Passiflora 'Byron Beauty' Complex tetraploid P. incarnata x P. edulis Robert Knight USA 1979 Min 0°C 32°F July-Oct To quote Dr Roland Fisher, P.'Byron Beauty' was selected from a large group of plants developed by Dr. Knight (USDA). In summer 1979, a clone of P. incarnata collected by H.F. Winters in Maryland was crossed with three introductions of P. edulis: P. 424813, a purple-fruited form collected wild in Brazil, P. edulis f. flavicarpa and an intraspecific hybrid derived from crossing a purple fruited strain from Australia ('Norfolk Island') with a clone of P. edulis f. flavicarpa (P. 243804) brought to Florida from Trinidad. Resulting offspring was tetraploidized and intercrossed. |
