Black Prince

Black Prince is an open-pollinated heirloom tomato originating from Irkutsk, Siberia. Classified botanically under Solanum lycopersicum, the cultivar develops as an indeterminate vine bearing standard regular-leaf foliage. It produces clusters of medium-sized, globular to slightly oblate slicing fruits that transition from green into a striking deep garnet-brown to mahogany hue capped by dark green to brownish-black shoulders.

Among dark Russian heirlooms, Black Prince is noted for its smooth, uniform fruit morphology and juicy, deep reddish-brown flesh. The cultivar delivers a moderate to high yield of medium slicers characterized by high sweetness, balanced acidity, and an earthy, tangy undertone, making it a favored choice for fresh culinary use.

Origin and Genetics

Black Prince, also recorded under the Russian name Chernyi Prints, originates from the city of Irkutsk in the Siberian region of Russia. It is a stable, open-pollinated heirloom cultivar preserved for its distinctive fruit coloration and reliable performance. Within botanical collections and heirloom registries, it is frequently evaluated alongside other prominent dark Russian selections while remaining genetically distinct in its fruiting uniformity.

Botanical Profile

The plant exhibits an indeterminate growth habit supported by standard green, regular-leaf foliage and yellow blossoms. The medium-sized fruits are typically globular to slightly oblate with a smooth surface and minimal to no ribbing. As the fruit develops, it retains chlorophyll in the upper shoulder tissue, creating a dark green to brownish-black cap over a mature mahogany, garnet-red, and purplish-brown base. Internally, the flesh is deep reddish-brown, tender, and noticeably juicy.

Growth and Performance

Black Prince performs as a vigorous vining tomato with an ongoing flowering and fruiting cycle throughout the season. It is documented as having a moderate to high yield capacity. The cultivar is adapted for standard open-field cultivation as well as protected greenhouse environments.

Flavor and Aroma

The culinary reputation of Black Prince centers on its rich and sweet flavor profile. It combines high natural sweetness with a balanced acidity and earthy, tangy accents characteristic of dark-pigmented heirloom tomatoes. The high juice content complements its complex flavor when consumed fresh.

Cultivation

Successful production requires full sun exposure and planting in fertile, well-drained soil. Because the vine is indeterminate, plants benefit from sturdy trellising, staking, or caging to support the continuous fruit load and maintain foliage health across both field and greenhouse settings.

Culinary Applications

Black Prince is primarily classified as a fresh-market slicer. Its tender texture, balanced acidity, and rich mahogany color make it well suited for fresh slicing and salads, where its distinctive internal and external pigmentation can be showcased.
