I have a volunteer eggplant that came up in the garden this summer.  It is tall and vigorous but the fruit that's being produced is a bright yellow?!  The only eggplant I've planted in this garden is a white variety I had a couple of years ago.  The yellow fruits are small -- 3-4" long and about 1" diameter.  They appear healthy and when I sliced one open it looks like it would be edible.  But I'm wondering... Yellow?!  Any idea what I have growing here?

Thanks
