desertwoman, I think mine blooms at Halloween because that's almost half way between Canadian Thanksgiving and American Thanksgiving. ;) Or, more realistically, because I take it outdoors in summer, so when it returns to indoors it feels the need to bloom.
@bluelacedredhead the shape of the leaves will tell you which it technically is but day length can make it bloom at a different time than is traditional. Either way they are so beautiful. I was looking at some in the greenhouse yesterday but didn't buy one because I know that my cats would eat it. Grrr.
