I put 4 poinsettia plants outside for the summer, cut them way back and
fed and watered them all summer. Brought them in in October, put them in
a window in the sunroom that faces south. They all bloomed and are still
blooming. We rarely have a light on in the sunroom at night, so the
hours of darkness worked fine for them. They are tall, instead of low
and bushy.
I think it was worth it, and, a challenge.
