I've not had a poinsettia for several years. I usually buy one at the church in memory of my parents, but instead of picking it up after Christmas, I tell my friend Patty - who is the church secretary - to keep it in her office.
The past few years when I worked at the plant place doing commercial Christmas decorations, we had them. There were always extra, so a couple times I brought one home. I didn't have much luck with them, so gave them to my neighbor. Unfortunately I didn't work there this Fall, due to them losing a major contract, so I won't have have any to give out.
