Some seeds of Aeonium x Sventenii, which is a naturally occuring hybrid between Aeonium Simsii, and Aeonium Manriqueorum (arboreum). I would guess the offspring from these F2 seeds would still be considered x Sventenii...
There's plenty of seeds. These flowers were open since the cold spell we had earlier this spring. With some luck, some of the seedling will show improved cold tolerance.
