There's a thread about poinsettias somewhere on this forum - just use the search feature.
This was a small poinsettia from last year, planted in the garden after the holiday. It was so small, it barely peeked over the retaining wall visible at the bottom of the picture. I did nothing but cut it back when the blooms withered, because I wanted to see if it would bloom with nature in charge. It's turning red and has buds, but won't make it by Christmas. It may have been slowed down by the neighbor frequently leaving his side yard light on all night. Luckily the heavy rains haven't hurt it.
