For gardeners seeking a truly gourmet tomato that offers both visual drama and a sophisticated taste, understanding the nuances of this heirloom is essential. Its robust growth habit, generous yields, and relative resilience make it an accessible choice for many, yet its distinctive characteristics set it apart from the common garden fare, inviting a deeper appreciation for the diversity of the plant kingdom.

Tracing the Roots: Origin and Legacy of the Paul Robeson Tomato

The story of the ‘Paul Robeson’ tomato is as intriguing as its flavor. Unlike many heirlooms with ambiguous or long-lost origins, this variety has a relatively clear and touching narrative. It hails from Russia, where it was named in honor of Paul Robeson, the iconic American bass-baritone singer, actor, and civil rights activist. Robeson was a highly regarded figure in the Soviet Union due to his outspoken advocacy for peace, equality, and workers’ rights, resonating deeply with Soviet ideals during the mid-20th century.

The tomato seeds were originally collected by Marina Danilenko, a Russian seed collector, during the challenging years following the collapse of the Soviet Union. Danilenko’s dedication to preserving unique and culturally significant varieties led her to share these seeds with Western seed savers, including the renowned American tomato expert Gary Ibsen of Tomatofest. Ibsen played a pivotal role in introducing the ‘Paul Robeson’ tomato to the broader gardening public in North America and beyond. He recognized its exceptional qualities immediately, promoting it as a premier “black” heirloom. The formal introduction of this variety to the Western seed market occurred in the early 1990s, where it quickly garnered a loyal following. Its name serves as a poignant reminder of Robeson’s global influence and the unexpected ways in which human culture and horticulture can intertwine.

As an heirloom, ‘Paul Robeson’ means it is an open-pollinated variety that has been passed down through generations, maintaining its distinct genetic characteristics. These plants grow true-to-type from seed, provided they are not cross-pollinated with other varieties. This lineage ensures that the unique qualities that make ‘Paul Robeson’ so special are preserved for future gardeners, allowing them to experience the same magnificent fruits grown decades ago.

Unpacking the Distinctive Characteristics

The allure of the ‘Paul Robeson’ tomato lies in its multifaceted appeal, a combination of striking visual aesthetics, a complex flavor profile, and a pleasing texture. Understanding these characteristics is key to appreciating its status as a top-tier heirloom.

Appearance: A Study in Dark Hues

• Size and Shape: ‘Paul Robeson’ produces large, typically beefsteak-type fruits, often weighing between 8 to 16 ounces, though some can grow even larger. They are generally oblate (flattened globe) in shape, sometimes with slight irregularities or ribbing, which is common among large heirloom varieties.
• Coloration: This is arguably its most captivating feature. Despite being categorized as a “black” tomato, its color is a sophisticated blend rather than a true black. Ripe ‘Paul Robeson’ tomatoes display a deep, dusky brick-red or mahogany hue, often with significant olive-green or brownish-green shoulders that persist even when fully ripe. This unique interplay of colors creates a visually rich and distinctive appearance. The interior flesh mirrors this depth, often presenting as a deep reddish-brown with multiple seed cavities.
• Skin and Structure: The skin is relatively thin and tender, which contributes to its pleasant eating experience but can make it slightly more prone to cracking in inconsistent watering conditions, a trait common among many large heirloom varieties. The fruit’s structure is typically multi-locular, meaning it has several seed compartments, leading to a substantial, meaty core.

Flavor Profile: A Symphony of Sweetness and Smoke

The flavor of the ‘Paul Robeson’ tomato is where it truly shines and commands its reverence. It is consistently rated among the best-tasting tomatoes, often surpassing even other highly-regarded “black” varieties.

• Complexity: The flavor is profoundly complex and balanced. It delivers a rich, sweet earthiness interwoven with distinct smoky undertones. This unique smoky quality is a hallmark of the ‘Paul Robeson’ and sets it apart.
• Sweetness and Acidity: It possesses a high sugar content, contributing to its luscious sweetness, which is beautifully balanced by a moderate acidity. This balance prevents the tomato from being cloyingly sweet or overly tart, resulting in a harmonious, full-bodied taste.
• Umami: Like many “black” tomatoes, ‘Paul Robeson’ offers a strong umami component, adding depth and a savory richness that makes it incredibly satisfying.
• Juiciness and Aroma: The fruits are exceptionally juicy, making them ideal for slicing, yet they maintain a firm, meaty texture. A ripe ‘Paul Robeson’ also emits a wonderfully fragrant aroma, hinting at the flavor experience to come.

Texture: Meaty and Tender

Beyond its color and flavor, the texture of ‘Paul Robeson’ tomatoes is also highly desirable. The flesh is dense and meaty, yet tender enough to melt in the mouth. It’s not watery or pulpy, ensuring a substantial bite. This combination of meatiness and juiciness makes it incredibly versatile for various culinary applications, from fresh eating to cooking.

Mastering the Art of Cultivation: Growing Paul Robeson Tomatoes

Cultivating ‘Paul Robeson’ tomatoes, like most heirlooms, requires attention to detail but is highly rewarding. These are indeterminate varieties, meaning they will continue to grow, flower, and produce fruit until frost. This characteristic necessitates specific care and support.

Seed Starting and Germination

• Timing: Start seeds indoors approximately 6-8 weeks before your average last frost date. This gives seedlings a good head start before transplanting them outdoors.
• Method: Use sterile seed-starting mix in trays or small pots. Plant seeds about ¼ inch deep.
• Environment: Maintain a consistent temperature between 75-85°F (24-29°C) for optimal germination. Provide ample light, either from a south-facing window or, ideally, under grow lights for 14-16 hours a day to prevent legginess. Keep the soil consistently moist but not waterlogged.
• Hardening Off: Before transplanting, gradually acclimate seedlings to outdoor conditions over 7-10 days. This process, known as “hardening off,” involves progressively exposing them to sun, wind, and cooler temperatures to minimize transplant shock.

Transplanting and Site Selection

• When to Transplant: Only transplant outdoors after all danger of frost has passed and night temperatures consistently remain above 50°F (10°C). The soil should also be adequately warmed.
• Sunlight: Choose a location that receives full sun, meaning at least 6-8 hours of direct sunlight per day. Tomatoes are sun-loving plants, and ‘Paul Robeson’ is no exception.
• Soil Requirements: ‘Paul Robeson’ thrives in fertile, well-draining soil with a pH between 6.0 and 6.8. Amend your soil generously with compost or well-rotted manure prior to planting to improve structure, fertility, and drainage.
• Spacing: Space plants 2-3 feet apart in rows that are 3-4 feet apart. Proper spacing ensures good air circulation, which is crucial for preventing fungal diseases. When planting, bury the stem deeper than it was in its pot, as tomatoes can grow roots along the buried stem, leading to a stronger root system.

Ongoing Care for Robust Growth

• Watering: Consistent and deep watering is paramount, especially once fruits begin to set. Irregular watering can lead to issues like blossom end rot (a calcium deficiency exacerbated by fluctuating moisture) and fruit cracking. Aim for 1-2 inches of water per week, depending on weather and soil type. Water at the base of the plant to avoid wetting foliage, which can promote fungal diseases. Mulching around the plants helps conserve soil moisture and suppress weeds.
• Fertilization: Start with a balanced organic fertilizer at planting. Once flowers appear and fruits begin to set, switch to a fertilizer higher in phosphorus and potassium to support fruit development, while reducing nitrogen, which encourages leafy growth at the expense of fruit. Compost tea or liquid seaweed extracts can provide excellent supplementary feeding.
• Staking and Support: As an indeterminate variety producing large fruits, ‘Paul Robeson’ requires robust support. Strong stakes, sturdy cages, or trellises are essential to prevent the plants from sprawling, protect fruits from soil contact, and manage their vigorous growth. Begin supporting plants early to train them.
• Pruning: Pruning suckers (the shoots that grow in the crotch between the main stem and a leaf branch) is a common practice. Removing suckers can direct the plant’s energy into producing larger fruits and improve air circulation, potentially reducing disease risk. However, excessive pruning can reduce overall yield and expose fruits to sunscald. A balance is often recommended, removing some lower suckers and those that are growing inward.
• Pest and Disease Management: Keep a watchful eye for common tomato pests like hornworms, aphids, and whiteflies. Hand-picking, insecticidal soaps, or biological controls can be effective. Preventative measures for diseases include good air circulation, watering at the base, crop rotation, and selecting disease-resistant varieties if possible (though heirlooms are not typically bred for disease resistance). Common diseases like early blight, late blight, and fusarium wilt can affect tomatoes, so prompt identification and action are important.

Climate Considerations

‘Paul Robeson’ performs best in warm, sunny conditions typical of a long growing season. While it exhibits good vigor, extreme heat can sometimes lead to blossom drop or reduced fruit set. Providing some afternoon shade in regions with intense summer heat can be beneficial. It is generally not more susceptible to common tomato problems than other large heirlooms, but its delicate skin might be slightly more prone to cracking if watering is inconsistent.

Harvesting the Bounty and Preserving the Flavor

The anticipation of harvesting the first ripe ‘Paul Robeson’ tomato is a highlight of the gardening season. Knowing when and how to pick them, along with proper storage, ensures the best possible eating experience.

When to Harvest

• Coloration: ‘Paul Robeson’ fruits are ready for harvest when they have fully developed their characteristic deep mahogany-red color with the distinct olive-green shoulders. The green shoulders will remain, but the overall color of the fruit will deepen significantly.
• Feel: Gently squeeze the fruit. It should feel slightly soft to the touch, but not mushy. A firm fruit that still feels hard is likely not fully ripe.
• Days to Maturity (DTM): ‘Paul Robeson’ typically has a DTM of 75-90 days from transplanting, making it a mid-to-late season variety. Be patient, as waiting for full ripeness on the vine yields the best flavor.

Harvesting Technique

Always handle ‘Paul Robeson’ fruits gently. Twist the fruit gently from the vine, or preferably, use clean garden clippers or snips to cut the stem just above the calyx (the leafy cap at the top of the fruit). This helps prevent damage to both the fruit and the vine, and leaving the calyx attached can sometimes help the tomato store a little longer.

Storage Best Practices

Proper storage is crucial for maintaining the exquisite flavor and texture of ‘Paul Robeson’ tomatoes.

• Room Temperature: The golden rule for tomatoes is to never refrigerate them. Cold temperatures degrade the flavor compounds and can make the flesh mealy. Store ripe tomatoes at room temperature (ideally 60-70°F or 15-21°C), away from direct sunlight, stem-side down to slow moisture loss.
• Shelf Life: Fully ripe ‘Paul Robeson’ tomatoes will typically last for 3-7 days at room temperature.
• Ripening Unripe Fruits: If you pick slightly under-ripe fruits before a frost, they can be ripened indoors. Place them in a paper bag with a banana or apple (which release ethylene gas) at room temperature. They won’t achieve the full complexity of vine-ripened tomatoes, but they will still be enjoyable.
• Preservation: For long-term storage, ‘Paul Robeson’ tomatoes are excellent candidates for canning, freezing, or dehydrating. Their rich flavor translates well into sauces, pastes, and roasted preparations, allowing you to enjoy their unique taste long after the growing season ends.

Culinary Versatility: Enjoying the Paul Robeson Flavor

The extraordinary flavor profile of the ‘Paul Robeson’ tomato makes it a culinary darling, suitable for a wide array of dishes where its complex taste can truly shine. Its balance of sweetness, smokiness, and umami ensures it enhances, rather than overwhelms, other ingredients.

• Fresh Eating: This is arguably where ‘Paul Robeson’ is best experienced. Sliced thick, sprinkled with a touch of sea salt, and perhaps a drizzle of good olive oil, it makes an unforgettable snack or appetizer. Its meaty texture and abundant juice make it perfect for:
  • Sandwiches: Elevate any sandwich with a substantial slice of ‘Paul Robeson’. Its robust flavor pairs wonderfully with classic deli meats, cheeses, or even simple avocado and sprouts.
  • Salads: A star in caprese salads with fresh mozzarella and basil, or as a vibrant addition to mixed green salads. Its deep color adds visual appeal.
  • Salsas and Bruschetta: Dice finely for fresh salsas, pico de gallo, or as a topping for bruschetta, allowing its fresh, earthy notes to come through.
• Sauces and Soups: While often reserved for fresh eating, its meaty flesh and rich flavor make it an excellent choice for cooked applications.
• Pasta Sauces: Its natural sweetness and depth contribute to a rich, complex tomato sauce. Cook down with aromatics for a truly gourmet experience.
• Soups: A fantastic base for fresh tomato soups or gazpacho, where its distinct character can be highlighted.
• Roasting: Roasting ‘Paul Robeson’ tomatoes intensifies their sweetness and smoky notes. Halve or quarter them, toss with olive oil, herbs, and garlic, and roast until caramelized. Roasted tomatoes can be used in salads, as a side dish, or blended into a rich sauce.
• Juicing: For those who appreciate fresh tomato juice, ‘Paul Robeson’ offers a uniquely flavorful and rich beverage.
• Preserving: As mentioned, its excellent flavor translates wonderfully to canning and freezing, allowing you to capture the essence of summer for use in colder months. Its substantial flesh holds up well to processing.

The key is to let the tomato’s natural flavor be the star. Simple preparations often yield the best results, showcasing the intricate balance that makes ‘Paul Robeson’ so exceptional.

The Art of Seed Saving: Ensuring Future Generations of Paul Robeson

One of the most rewarding aspects of growing heirloom tomatoes is the ability to save your own seeds, perpetuating the legacy of these extraordinary varieties. ‘Paul Robeson’ is an open-pollinated heirloom, meaning its seeds will produce plants true to the parent, provided careful seed-saving practices are followed.

Why Save Seeds?

• Preservation: Saving seeds helps maintain genetic diversity and ensures that cherished varieties like ‘Paul Robeson’ continue to thrive for future generations.
• Cost Savings: Once you have a healthy plant, you can produce an endless supply of seeds without needing to purchase them again.
• Adaptation: Over time, seeds saved from your garden may subtly adapt to your specific microclimate and growing conditions, potentially leading to more resilient plants.

The Fermentation Method for Wet Seeds

Tomato seeds are encased in a gelatinous sac that inhibits germination. Fermentation breaks down this sac and helps kill seed-borne diseases.

1. Select Prime Fruits: Choose fully ripe, healthy, and representative ‘Paul Robeson’ tomatoes from vigorous plants. Avoid any fruits that show signs of disease or pest damage.
2. Extract Seeds and Pulp: Cut the tomatoes in half and squeeze the seeds and gelatinous pulp into a clean jar or container. Add a small amount of water if necessary to fully cover the pulp.
3. Ferment: Cover the jar loosely (to allow gas exchange) with a lid, cheesecloth, or paper towel secured with a rubber band. Place it in a warm location, out of direct sunlight. Over 2-5 days, a layer of mold will form on the surface, and fermentation will occur. Stir daily. The fermentation is complete when the mold is thick, the seeds have sunk to the bottom, and the mixture smells yeasty (not rotten).
4. Rinse and Clean: Once fermentation is complete, carefully pour off the moldy liquid and any floating debris. Add fresh water to the jar, stir, and let the viable seeds sink to the bottom. Repeat this rinsing process several times until the water is clear and the seeds are clean.
5. Dry Thoroughly: Spread the clean seeds in a single layer on a non-stick surface, such as a ceramic plate, glass pane, or parchment paper. Avoid paper towels, as the seeds may stick. Place them in a well-ventilated area away from direct sunlight or heat. Stir the seeds daily to ensure even drying. Seeds should be completely dry (snapping in half rather than bending) within 1-2 weeks. Any residual moisture can lead to mold and failure to germinate.
6. Store Properly: Once absolutely dry, store ‘Paul Robeson’ seeds in airtight containers (e.g., small glass jars, plastic baggies) in a cool, dark, and dry place. A refrigerator or freezer can extend viability significantly. Label clearly with the variety name and date saved. Properly stored tomato seeds can remain viable for 5-10 years or even longer.

While tomatoes are largely self-pollinating, cross-pollination can occasionally occur, especially in home gardens with many varieties planted closely. To ensure pure ‘Paul Robeson’ seeds, plant them a reasonable distance from other tomato varieties (typically 10-20 feet for home gardens) or bag blossoms before they open to prevent insect visitation, if absolute purity is desired.
