Poinsettia's came to us from America and are in fact a native of Mexico. The great thing about these plants is that they produce a mass of bright sldier red bracts that can last for up to 12 weeks a year and just one or two plants can transform a room into an instant feeling of Christmas.
Poinsettias can be kept going for a long time and we do have care leaflets just for this purpose. Alternatively they can be thrown out when the bracts begin to fade and the plant has done it's rather awsome job.
Looking After The Poinsettia
Remember these plants originally came from Mexico so that is what we need to consider.
Keep them warm and away from draughts and don't place them on the windowsill where temperatures and light fluctuate widely. Give them bright light and a warm position instead.
When watering just feel the pot by pressing your finger into the compost. Water from the top, but only if the compost feels dry, always allowing the water to drain away.
The bracts will drop when the days start to lengthen, the Poinsettie is an equal day length plant, called a short day plant, this plant and likes an equal 12 hours of day light and 12 hours night to produce flower bract. But you don't have to worry about that for some time after Christmas - until after the spring equinox.
