Same here ... Sometimes Yes, Sometimes No.
Even though Poinsettia's grow here in Florida I have trouble keeping them alive for some reason. For many years I'd decorate with many Poinsettia plants both inside and outside the house. Two years ago I had about 15 or 20 and they were really beautiful. After the holidays I planted them in the yard and they did well for a few months but one day I noticed that some critter had crushed and broken branches on many of them so I cut them way back. They had lots of new growth and were looking really good again when a month or two later they suddenly all died! The master HOA in our subdivision has a boat that goes throughout the waterways spraying the weeds along the shoreline and I really think the chemicals killed them! Grr ... I wish they wouldn't spray along our property line; a few weeks ago I noticed dead grass along our property and the Clerodendron's behind our screened porch look to have been burned from overspray!
This year I haven't bought one Poinsettia but I'm just getting over a 3 1/2 week bout with severe bronchitis so I never even thought about buying any this year ... maybe 2014.
