So with the holiday season coming, I recently found my self in possession of a poinsettia plant. Given my recent successes with other green growing things blsmoke I decided "hey this could be fun to try and grow rather than just letting it wilt and throwing it out after Christmas!" Well after reading up a little on it, I have to say it sounds like a lot of work! It seems to have rather more stringent growing requirements. Like its window of acceptable temperatures sounds much smaller than Mary Jane's. Oh also in case you're interested, the Poinsettia plant is another example of a plant that has to fall below some minimum threshold of lighting hours in order to bloom.
