I started my pepper plants and onions this past Sunday. This is how I deal with them, keeping them warm from the radiator and placing them in the SE window, the only one where I get enough light. This worked really well last year.
Here are some pictures from my indoor houseplants:
This is my jasmine vine. It is really doing well, I transplanted it last summer into this larger plastic pot. It does bloom through the winter. Notice the long tendril growing above the trellis.
These are my red shamrocks, actually a variety of oxalis. It is a tuber, or a corm. I can't remember which. I gave this to mom years ago for her office, but when she retired she gave them back. I repotted them and FOOM there they went.
This is the Christmas cactus that Tim gave me last October. Notice the new growth at the dirt level as well as the new grow at the tip ends. This was a cutting from his grandmother's plant.
