Exploring the Unique Qualities of Purple Cherry Tomatoes
For many gardeners and food enthusiasts, the bright red cherry tomato is a familiar staple. However, the world of tomatoes is vast, and varieties with dark, rich hues are gaining popularity. Among these, purple cherry tomatoes stand out, not just for their aesthetic appeal but for their impressive nutritional profile and complex flavor palette. Unlike a simple red tomato, the experience of a purple variety is multi-faceted, with taste and benefits varying significantly between different cultivars. The question of whether purple cherry tomatoes are good depends heavily on what you value in a tomato—be it their rich, savory flavor, their high antioxidant content, or their visual appeal in a dish.
The Flavor Profile: Beyond Sweet
One of the most common misconceptions about purple cherry tomatoes is that their flavor is one-dimensional. In reality, these tomatoes offer a nuanced and often more complex taste than their red counterparts. For instance, the bioengineered 'Norfolk Purple Tomato' is described as having a low-acid, savory, and earthy flavor. Other heirloom varieties, like 'Black Cherry', are celebrated for their rich, tangy flavor that is perfect for snacking right off the vine. The 'Indigo Rose', one of the first varieties with a true purple skin due to high anthocyanin levels, has a balanced sweet-tart taste. The intensity of the flavor can also depend on ripeness, with some growers noting that underripe fruits can taste bland, while properly ripened ones are full of character. This diversity means there is likely a purple cherry tomato variety to suit every palate, whether you prefer a mild complement to a salad or a bold, complex snack.
Significant Health Benefits
Purple cherry tomatoes are more than just a pretty face; they are a nutritional powerhouse. The deep purple coloration is caused by high levels of anthocyanins, the same potent antioxidants found in blueberries and red cabbage. These compounds offer a range of health benefits, including:
- Enhanced Antioxidant Capacity: Anthocyanins combat free radicals in the body, which can help reduce oxidative stress and inflammation.
- Anti-inflammatory Properties: The potent anti-inflammatory effects of anthocyanins have been linked to reducing the risk of chronic diseases.
- Cardio-protective Effects: Studies suggest that higher antioxidant intake is associated with a lower risk of heart disease.
- Anti-cancerous Properties: Anthocyanins have demonstrated anti-cancer effects in lab studies, showing promise in the prevention of certain cancers.
- Neuroprotective Effects: These antioxidants may also contribute to neurological health, protecting against diseases like Alzheimer's and dementia.
This makes purple cherry tomatoes not only a tasty addition to your diet but a proactive step towards better health. For more on the science behind these benefits, research published by the National Institutes of Health offers valuable insights on the antioxidative properties of tomatoes.

Purple vs. Red Cherry Tomatoes: A Comparison
| Feature | Purple Cherry Tomatoes (e.g., Indigo Rose) | Red Cherry Tomatoes (e.g., Sungold) |
|---|---|---|
| Appearance | Deep purple to nearly black skin, with red interior flesh. | Bright red or orange skin and flesh. |
| Flavor Profile | Complex and varied, often described as sweet-tart, earthy, or rich and tangy. | Typically a classic sweet, juicy, and often high-acid tomato flavor. |
| Antioxidants | Significantly higher levels of anthocyanins, similar to blueberries. | Primarily known for the antioxidant lycopene. |
| Ripeness Indicator | Judge by softness and a deeper, duller color; not by bright red color. | Judge by classic red color and softness. |
| Growth Habit | Varies by variety; some are indeterminate, others are semi-determinate. | Varies widely by variety; includes both determinate and indeterminate types. |
Growing Your Own Purple Cherry Tomatoes
Cultivating purple cherry tomatoes is very similar to growing any other cherry tomato, with a few key considerations to maximize their unique potential:
- Plenty of Sunlight: Ensure your plants receive at least 6-8 hours of direct sun daily. This is crucial for fruit development and flavor intensity.
- Rich, Well-Draining Soil: Use soil rich in organic compost. A slightly acidic to neutral pH is ideal for most varieties.
- Consistent Watering: Maintain even moisture in the soil. Inconsistent watering can lead to problems like blossom-end rot or cracking, especially in hot weather.
- Support Systems: Many purple cherry tomato varieties are indeterminate and require support from stakes, cages, or trellises to manage their vigorous growth and keep fruit off the ground.
- Fertilizing: Start with a low-nitrogen fertilizer during planting, and switch to a formula with more phosphorus and potassium once flowering begins to encourage fruiting rather than excessive foliage growth.
Conclusion
Ultimately, the verdict on whether purple cherry tomatoes are good is a resounding 'yes,' especially for those looking to expand their culinary and gardening horizons. Their delicious and varied flavors, coupled with an impressive antioxidant content, make them a compelling choice. While some varieties may have a more subtle taste profile or require more careful attention to ripeness, the health benefits alone offer a significant reward. Whether you're adding them to a salad, roasting them with herbs, or simply snacking on them fresh, purple cherry tomatoes bring a vibrant color and a boost of nutrition to any meal.
Frequently Asked Questions
Are purple cherry tomatoes sweeter than red ones? It depends on the variety. Some purple cherry tomatoes, like Purple BumbleBee, are quite sweet, while others, like Indigo Rose, offer a more complex sweet-tart balance. Red varieties also have a wide range of sweetness, so it's best to research specific cultivars.
How can you tell if a purple cherry tomato is ripe? Since the color is not a reliable indicator for all varieties, you should check for softness. A ripe tomato will give slightly when gently squeezed, similar to other tomatoes. The bottom of the fruit may also show more red color, while the purple deepens or becomes more dull.
Do purple cherry tomatoes have any unique health benefits? Yes, their deep purple color comes from anthocyanins, powerful antioxidants that are not found in high concentrations in red tomatoes. These have anti-inflammatory, anti-cancer, and cardio-protective properties.
Are purple cherry tomatoes genetically modified? Not all of them. While a specific bioengineered 'Norfolk Purple Tomato' exists, many purple varieties, such as Indigo Rose and Black Cherry, were developed through traditional cross-breeding and are considered heirlooms or hybrids.
What are the best uses for purple cherry tomatoes? Their complex flavor profiles make them excellent for salads, roasted vegetables, pasta, and fresh snacking. They also add a visually stunning element to any dish.
Do purple tomatoes taste earthy? Some, but not all. The flavor can range from rich and earthy to sweet and tangy, depending on the specific variety and its unique characteristics.
Can you save seeds from purple cherry tomatoes? For heirloom varieties like 'Black Cherry', you can save the seeds. However, for hybrid varieties such as 'Indigo Rose' or 'Midnight Snack', saving seeds may not produce a plant with the same characteristics as the parent.
