I forgot to mention that to me it looks like Impatiens. Maybe she bought an annual not knowing that it's not a house plant and is keeping it inside.

Impatiens. If it looks that good as an indoor plant, then she is far better off keeping it inside! There is a disease that has been sweeping the country (and world) affecting impatiens. It's one of the Downy Mildew pathogens.

They are grown here both as bedding plants and as year round houseplants. I think Impatiens walleriana is the correct name. All our F2 Safari hybrids survived this year despite one of the wettest summers ever.

You can grow impatiens as house plants? Didn't know that, I'll have to get one and keep it indoors and try it.
