Flavor
Described as rich and complex, a smooth dark tomato that slices cleanly for salads or cooks into sauce. This is the recurring catalog and grower description, not a measured claim.
Origin
A Russian heirloom, despite the name, with pear-shaped mahogany fruit resembling a dark Bartlett pear.
What it does well
- Distinctive mahogany pear shape
- Smooth skin that resists cracking
- Rich, complex dark flavor and reliable yields
Where it frustrates
- Dark color makes ripeness hard to judge
- Indeterminate vines need staking
Growing it
- Indeterminate vine. It keeps growing and setting fruit right up to frost, so plan on a tall stake or cage and regular pruning through the season.
- Mid-season timing, ripening around 70 to 80 days from transplant.
- Generally forgiving and beginner-friendly to grow.
- Skins resist cracking, even after a heavy rain.
- One of our picks for the cold, short-season gardens of New England.
Disease resistance
An heirloom, sold without formal disease-resistance codes.
Why no hardiness zone?
Tomatoes are warm-season annuals, so variety choice comes down to days to maturity and your local frost dates.
