I read up on that once a long time ago. The attempt was to keep it going was not successful. The next year I bought a couple of very nice “silk” ones in a pot, and they have looked nice each year since.
Maybe someone else will have a better answer. LOL
Thanks. I’ve always been surprised that the poinsettia, despite it’s bright color and large size, usually has no fragrance. Maybe it’s been hybrided for commercial purposes for so long, that the fragrance or the natural occuring pollen has atrophied, or lost much of the oils needed for it’s smell. Those oils may only happen in mature plants. The immature species we buy in stores has no need to attract bees or birds, since it may be hand pollinated for a grower’s convienance.
