Thank you so much. That looks like what it is. I feel lucky to have found it.

I've had color intensity changes---mine go from med pink to pale pink and back again---on geraniums (pelargoniums). Probably due to weather conditions, etc. Becky

Your grandmother has the right idea for her locality..cold, northern Iowa. Us northern folks get the wrong idea about southern locales; New Mexico suggests warm weather when approaching January....in California January is the month they plant so naturally..... You can keep your geranium going with the amount of sun you have as long as possible...but as soon as it wilts, cut it back to about 4", remove any old leaves and bloom, any weak or damaged stems or branches; re-plant in a fresh pot with fresh potting soil or potting mix. Put something in the pot between the soil and the drainage holes. Put it in the best sunny window you can...south or west is best and water to drainage. No more water until the new leaves form, then water only as the plant needs it. Do not fertilize until well along in foliage. Normally, up north we bring our geraniums out by the Ides of March..(15th) and do the same thing. We suspect New Mexico will have better sun pretty soon. Its all up to the sun....its still low but getting better every day. Turn the plant every day or so to ensure all parts get equal sun. When you water, always water to drainage, then dump the excess in the saucer. Let it dry down somewhat between waterings. Within 2 weeks you will have a fresh measure of leaves and more each day. It will bloom later when the sun is better.

You don't really want a Pelargonium plant that small to flower yet. It should be busy building itself up, as yours is. They also need reasonably warm temps and sunshine to flower. It will be obvious when it is going to bloom because the flower stalk will elongate and you will see a cluster of buds.
