‘Carbon’ is a celebrated black heirloom beefsteak, producing big, blocky-round fruit that ripens from dark olive shoulders to a deep brick red. It is grown above all for flavor — rich, complex, and full, with the dense, meaty texture prized in dark tomatoes.

A better-behaved black

Large black tomatoes are notorious for cracking and cat-facing, but ‘Carbon’ resists both better than most, while keeping a well-balanced, productive plant. It is grown to USDA Organic standards.

Care tips

Grow in full sun with strong staking or caging for the indeterminate vines. Harvest when the fruit has fully colored and gives slightly to a gentle squeeze.
