Indeterminate, mid-season leaning late, great fresh-market salad slicer. Good production overall. The fruit is red and heart-shaped, sometimes coming out as a flattened heart, and I even had several fused double hearts on the vine.
The tomatoes are juicy with very good, sweet flavor. Grown in the greenhouse, yields were a notch above average. Seeds came from T. Kouchnareva.
