Hello Bob, H. puniceum var alberti is a double species form and most of the double hybrids today originated from it. Only very few doubles have a pistil and are generally not fertile, but some are. I grow only one like this, a local hybrid from Taiwan. There are also methods to triger doubles in Hippeastrum and other Amaryllidaceae genera. Forgot how it is called, but a certain chemical is used to create double Zephyranthes, this I know for sure. I am convinced there are some other similar methods that the Dutch breeders use + the genes from H. puniceum var alberti or its hybrids. Hope this helps, Vlad Hempel +4915777291232https://http://www.linkedin.com/in/vhempel/ On Wednesday, January 27, 2021, 09:50:34 PM GMT+1, Robert Lauf via pbs <pbs@lists.pacificbulbsociety.net> wrote: Can anyone advise on how double flowering is inherited in Hippeastrum? I have pods going on several plants using pollen from Marquis, a large white double. The Marquis didn't have anything that looked like a recognizable pistil, but did make enough pollen for several crosses with other things.
