This tomato is a total mystery to me. I have grow 3 different seed sources of black prince, 2 seed sourses of purple prince 1 seed source of chyornyi prince 1 seed source of purple price and 1 seed source of black price. Most all of them produced a productive early roundish tomato red brown mahogany in color "the imposter" with an exception of a few. I love this tomato. love love love this tomato. It is mass productive and around 70ish days. I process allot of sauces and tomato products and this tomato is solid and very good for darkening sauces. I recommend you find imposter seeds and grow them. I have grown then for about 10 years and they are still my favorite. I got my chyornyi prince seeds from sampleseed.com for 1.25 a pack
Did I mention I love this tomato!!!
