Paul Robeson Tomato

A tomato that crossed the Iron Curtain in a seedswoman’s suitcase. Named after an American the Soviets loved more than America did.

Paul Robeson was a singer, actor, and civil rights activist. He visited Moscow in 1934 and said something no Black American had reason to say at home: “Here I am not a Negro but a human being for the first time in my life.” The Soviet government gave him the Stalin Prize in 1952. The U.S. government revoked his passport. He was blacklisted during the McCarthy era while the Soviets treated him as a hero.

Somebody in Russia named a tomato after him. Nobody knows who, or exactly when. What we know is that the variety existed in Russian gardens by the late Soviet period, and that its dark, blackening skin was understood as a deliberate reference to the man it honored.

In 1992, the Soviet Union had just collapsed. Marina Danilenko, who cofounded Moscow’s first private seed company with her mother, visited the Seed Savers Exchange in the United States. She brought 170 Russian tomato varieties with her. Paul Robeson was one of them. Jeff McCormack of Southern Exposure Seed Exchange introduced it to American gardeners through his catalog. A tomato bred in Russia, named after an American who was more celebrated there than here, crossed the ocean and landed in the gardens of the country that had rejected the man it was named for.

That is a lot of history for a tomato. What keeps Paul Robeson in American gardens is not the story. It is the flavor.

What the fruit is like

Paul Robeson produces medium to large beefsteak fruit. Most weigh 7 to 10 ounces. Strong plants in good soil produce individual fruit up to a pound or more. The shape is oblate, slightly flattened, with light ribbing near the stem end. The surface is often irregular. This is not a smooth, pretty tomato. It is a tomato that looks like it has something to say.

The color at full ripeness is deep mahogany to maroon with olive green to brownish shoulders that persist even when the fruit is fully ripe. The shoulders darken through the season. Cut one open and the interior runs beet red to deep wine. The color is part of the experience.

The flavor is where Paul Robeson separates from every other dark tomato in this guide. Growers use the word smoky more than any other word. Rich, earthy, smoky, with a savory depth that is more complex than Cherokee Purple and darker than Black Krim. There is sweetness, but it sits underneath a layer of umami that makes the tomato taste almost meaty. One grower on Dave’s Garden described “a subtle ham flavor.” That sounds strange until you taste it. Then it makes sense.

The acidity is moderate. Enough to give the flavor structure without the sharpness of a bright red slicer. The balance between sweet, acid, and savory is what makes people describe Paul Robeson as the best tomato they have ever grown. Not everyone agrees. But the people who love it are intense about it.

Days to maturity: 75 to 90 days from transplant. The range is wide because climate and conditions affect this variety more than most. In warm climates with long summers, expect the shorter end. In cooler regions, plan for 85 to 90 days actual.

Why the flavor is different from other dark tomatoes

American gardens now grow several dark and black heirloom tomatoes. Cherokee Purple, Black Krim, Black Cherry, Chocolate Cherry. Paul Robeson sits among them but tastes different from all of them.

Cherokee Purple is sweet and complex with a wine like tang. Black Krim is bold, salty, and aggressive. Paul Robeson is smoky. That smokiness is its signature and it does not appear in the others at the same intensity. Growers who have grown all three side by side consistently report that Paul Robeson delivers a flavor depth the others approach but do not reach.

The Russian heirloom tomato tradition prioritized flavor complexity over appearance and disease resistance. American breeding programs spent decades selecting for uniform color, firm skin, and shipping durability. Russian gardeners, growing for their own tables in short, intense summers, selected for the deepest, richest flavor they could get in limited growing time. Paul Robeson is a product of that tradition. The flavor reflects generations of selection by people who were eating what they grew, not selling it.

How to grow Paul Robeson, start to finish

Starting seeds

Start indoors 6 to 8 weeks before your last frost date. Sow seeds a quarter inch deep in a clean seed starting mix. Keep soil temperature between 70 and 80°F. A heat mat keeps germination fast and consistent. Some growers report slow initial sprouting with this variety. Give it a full two weeks before worrying.

Set up fluorescent or LED grow lights close to the canopy the day seedlings emerge. Keep them 2 to 3 inches above the plant tops. Raise them as growth continues. Paul Robeson is an indeterminate variety that can reach 6 feet or more. The stems are thinner and more open than many large tomato varieties. A seedling that stretches under poor light builds a weak stem that struggles all season.

Pot up to individual containers when the first true leaves appear. Feed weekly at half strength with a balanced liquid fertilizer from that point through transplant day.

Paul Robeson is open pollinated and grows true from saved seed. Scoop seeds and gel from a fully ripe fruit into a jar of water. Ferment for 2 to 3 days. Rinse and dry flat. Store somewhere cool and dry until spring. Save from the darkest, most flavorful fruit on your healthiest plants. That is how Russian gardeners developed this variety over generations. You are continuing their work.

Transplanting

Move plants outside after your last frost date, once nights hold reliably above 50°F. Cold nights below 54°F during flower formation cause catfacing. Paul Robeson produces large fruit and is susceptible to catfacing on the first flush. Wait for genuinely warm nights before planting out permanently.

Harden off over 7 to 10 days. Set plants outside for increasing periods each day before leaving them out permanently. Indoor seedlings moved directly to full sun and wind experience shock. A proper hardening period prevents that setback when you want roots going down fast.

Bury two thirds of the stem at planting. Tomatoes produce roots along any buried stem section. Strip any leaves that would go below soil level. Paul Robeson’s thinner stems benefit especially from the extra root depth and stability that deep planting provides.

Space plants 24 to 36 inches apart. Give it room. The canopy is open and lanky rather than dense and bushy. Air circulation matters because there is no disease resistance to fall back on.

Soil and feeding

Rich, well drained soil loaded with compost, pH 6.0 to 6.8. Work a balanced organic fertilizer into the planting hole before setting the plant in. This slow release base supports root development without pushing sudden leafy growth in the first weeks after transplant.

Switch to a lower nitrogen tomato feed once the first flowers open. High nitrogen after flowering drives leaf growth at the expense of fruit. This matters more with Paul Robeson than with some varieties because the plant already tends toward lanky, open growth. Too much nitrogen makes it worse. Feed every two weeks through the season.

Blossom end rot is a real risk on 7 to 10 ounce fruit. Consistent moisture is the fix. A compost rich soil base provides the calcium developing fruit needs. Irregular watering disrupts the uptake. Keep moisture even through the season. Skip the calcium spray products.

Light and water

Full sun, 6 to 8 hours minimum. Paul Robeson needs heat and light to develop its dark color and complex flavor. Growers in very hot climates report that afternoon shade actually helps. The fruit develops better color and richer flavor when it is not baking in direct sun through the hottest part of the day. In most climates, full sun is the right call. In the deep South or desert Southwest, afternoon shade is worth considering.

Water deeply and consistently at the base of the plant. Target 1 to 2 inches per week. Paul Robeson’s skin is thin and tender for a beefsteak. It cracks more readily than thick skinned varieties when moisture swings occur. Growers on forum threads consistently name cracking as the main frustration with this variety. A drip line or soaker hose keeps moisture steady and foliage dry.

Lay 2 to 3 inches of straw mulch around the plant after a deep watering. Mulch stabilizes soil moisture between rain events. It reduces the wet to dry swings that crack thin skinned fruit. It also stops soil spores from splashing onto lower leaves during rain, which matters on a variety with no disease resistance.

Support and pruning

Paul Robeson is fully indeterminate. It reaches 4 to 6 feet in most gardens. The growth habit is open and lanky rather than dense. Stems tend to be thinner than other beefsteak types. A heavy duty cage at least 5 feet tall, sturdy stakes, or a trellis system all work. Set the support at planting before roots spread.

Tie growing stems to the support with soft plant ties or strips of fabric. Nothing that cuts into swelling stems. Check and adjust ties every two weeks through the season. The thin stems need more attention than a thick, sturdy plant like Better Boy or Big Boy.

Remove suckers below the first flower cluster. This keeps the lower canopy open for airflow. Above the first cluster, let the plant develop two to three main leaders. Aggressive sucker removal above the first cluster reduces total yield without improving individual fruit quality on this variety.

Strip any foliage touching the ground. Soil to leaf contact is the primary entry route for early blight spores. Keep the lowest foot of the plant clear throughout the season. Strip spotted leaves the day you see them. With no resistance built in, catching problems early is the whole strategy.

Problems to watch

Cracking. The main ongoing challenge. Paul Robeson’s skin is thinner than most beefsteak types. A rain surge after a dry stretch splits ripe fruit readily. Pick when the shoulders have fully darkened rather than leaving ripe fruit on the vine. Consistent moisture and thick mulch prevent most splitting. Our tomato fruit problem guide covers cracking and every other common fruit symptom in detail.

No disease resistance. And no VFN coding. No early blight resistance. In beds with Fusarium, Verticillium, or nematode pressure, the plant declines faster than a resistant variety. Rotate beds each season. Water at the soil level. Rapid wilting in a plant that looks otherwise healthy often points to soil disease rather than a surface issue.

Early blight. No resistance. Brown spots with concentric rings on lower leaves, climbing from the base. Strip affected leaves immediately. Keep foliage dry. Rotate beds each season. On a plant with thin, open foliage, early blight can move fast once it gets established.

Catfacing. Cool nights below 54°F during flower formation cause it. On large fruit, catfacing shows clearly. First flush fruit may have significant scarring at the blossom end. Safe to eat. Trim and use it. Midseason fruit from the same plant comes in clean.

Blossom end rot. A real risk on medium to large fruit. Consistent moisture is the fix. Mulch the bed. Water evenly. Do not let the soil cycle between drought and flood.

Inconsistent fruit set. Some growers report seasons where Paul Robeson refuses to set fruit despite healthy foliage. This appears to be temperature related. Extreme heat above 95°F during flowering causes blossom drop. In very hot climates, the afternoon shade noted in the light section helps maintain fruit set through the hottest weeks.

Ugliness. This is not a problem. It is a characteristic. Paul Robeson fruit is often irregular, scarred, shouldered, and dark. It looks nothing like a grocery store tomato. That is fine. The flavor is the reason you grow it. Judge it by the taste, not the surface.

Container growing

Paul Robeson works in containers better than most large beefsteak varieties. The plant stays more compact than some indeterminate types, typically reaching 4 to 6 feet rather than 8. The fruit is medium to large but not as heavy as a 2 pound Brandywine. Growers on Dave’s Garden report reasonable yields in containers.

Use a 15 gallon container of quality potting mix at minimum. Set a tall stake or cage at planting. Water daily in summer heat. Feed every week to 10 days because containers flush nutrients fast. Expect smaller fruit and more cracking than ground grown plants produce. Consistent moisture in a pot is always harder than in the ground.

Paul Robeson vs other dark heirloom tomatoes

Cherokee Purple is the most widely grown dark heirloom and the closest comparison. Both are large, dark, complex, open pollinated, and carry no disease resistance. Cherokee Purple is sweet with a wine like quality. Paul Robeson is smokier and more savory. Growers who have grown both tend to find Cherokee Purple more approachable and Paul Robeson more interesting. Both are worth growing in the same season for the comparison.

Black Krim is the other Russian dark heirloom. Bold, salty, aggressive flavor. Paul Robeson is deeper and more layered than Black Krim. Both come from the Russian heirloom tradition, both reached American gardens through the same post Soviet seed exchange that brought 170 varieties to the Seed Savers Exchange. Black Krim cracks more. Paul Robeson develops more complex flavor in most conditions.

The verdict

Paul Robeson crossed the Atlantic in 1992 in a Moscow seedswoman’s collection. It has been building a following in American gardens ever since. The people who grow it tend to use words like “best tomato I have ever grown.” Not everyone agrees. But nobody who has tasted a ripe Paul Robeson forgets the flavor.

The smokiness is real. The complexity is genuine. The fruit is ugly and the plant is lanky and there is no disease resistance. None of that matters on the plate. This is a tomato you grow for flavor and nothing else.

Give it full sun, consistent water, real support, and patience. Pick when the shoulders darken fully. Eat it warm from the vine with salt. Save seed from the best fruit. That is how this variety survived decades in Russian gardens before it ever reached ours.
