I'm trying several hearts this year and I'm really impressed so far. Ukrainian Heart (also called Russian Heart), Anna Russian, Kosovo, German Red Strawberry, Russian 117 and Orange Russian 117. So far I have tasted Anna Russian and Ukrainian Heart and they are both off the charts as far as sweetness and taste goes. I would definitely give the Ukrainian Heart the slight edge in taste and sweetness, but the BER that comes with this tomato sucks. No BER on Anna Russian. Cant wait for the others to blush!
