Is there any plant that can grow in the dark?

I am trying to write a story and I would like to refrain from going into the "fantasy" realm, and as such I need to know if there is any such thing as a plant that can grow in the dark? Or by candlelight/fire light.

Yes, there are are few light independent plants, there are some plants that do not contain the pigment chlorophyl and do not photosynthesize.  Indian Pipe (also called ghost plant) is a flowering plant in the blueberry family.  It is one of about one of about 3000 species of non-photosynthetic plants (so there are actually quite a few plants that could potentially grow in the dark!). Because they do not contain chlorophyl they are usually white or grey and often confused with fungi, but there are indeed plants.  I've linked some pictures to Indian Pipe and a few of these other light independent species:

And if you're wondering, since they do not get energy from the sun where might they get it then, they are actually "mycoparasitic" meaning that they are parasitic on a particular fungus in the soil (that fungus usually has a mycorrhizal relationship with the roots of some other photosynthetic plant but that's probably more information than you were wanting)...
