Sweet Potato

I am a pretty good gardener but somehow I have the kiss of death on indoor plants. I don't know what it is they can be glossy and perfect and with in weeks of being in my house get all rangy and drop their leaves. Recently a sweet potato sprouted in my veggie basket, I do realise that says something for the state of my veggie basket. Any how it had the prettiest heart shaped leaves so I put it in a pot and now it is the most gorgeous plant. I have just moved it inside so we will see how long it lasts but in the meantime it is looking fantastic.
