Poinsettia.

I like the red ones because they look 'Christmassy' but I like other colours too, it's nice to have something more unusual :)

Blooming Poinsettias are not a common sight in gardens here in the southern hemisphere at this time of the year.

If they do appear in garden centres we know that they've been grown in light and temperature controlled glasshouses to trick them into thinking it's winter, and they're expensive.
