Solanum lycopersicum

HEIRLOOM All the components of an excellent saucing tomato – solid, meaty flesh and rich flavor with hardly any seeds. You’ll end up growing this every year to fill the pantry with jars of tomatoes! Elongated 9-11 oz fruit. Indeterminate. (0.15 Gram Packet)


The first bite of a friend’s homegrown tomatoes is the clarion call to gardening for many people. The flavor is incomparable and it lingers in our memories through the long winter days. And so begins the epic journey of devotion that is growing tomatoes. Native to the dry highlands of Peru, these plants are rather sensitive to the growing conditions found in much of the US, requiring some extra vigilance by the grower to mitigate plant diseases. Generally, they prefer good air flow from sturdy trellising and low humidity, although there are many varieties that have been selected to perform well under different conditions. The plants are either determinate, or indeterminate. On determinate plants the fruits ripen at one time and don’t necessarily need to be staked. Indeterminate plants continue growing until frost with fruit ripening until the plant dies. Nutrients: dietary fiber, vitamins A, C and K, potassium, manganese.

Tomatoes are frost-sensitive annuals that need full sun and evenly moist soil to thrive. Most varieties prefer caging, staking or trellising. Take care to water only the roots and soil, not the plant leaves to reduce risk of disease. Plant Seeds: Start indoors 6-8 weeks before last frost, planting 1/4" deep in 3-4" pots. Transplant after all danger of frost and when soil has warmed up, leaving 3' between rows and 18-24" between plants. When planting, sink plants very deep up to 12-18" deep, right up to the base of the first leaves. This will promote good root development. Soil Temp: 70-90 F. Days to Sprout: 6-14 days. Companions: asparagus, basil, bee balm, cabbage family, garlic, nasturtium, celery, parsley, onion, marigold. Antagonists: cabbage family, pole beans, dill, fennel, potato, corn. Seeds/Oz: 9,000. Average Yield/100' row: 150 lbs. Days to Harvest: 60-85 from date of transplant. Seed Viability: 4-7 years

    (verified owner):

    I ordered opalkas from sowtrueseed for the first time this year and have been incredibly disappointed. I’m growing six opalka plants. They are busy, healthy, and grow vigorously, setting tons of fruit. However, they look closer to a very large cherry tomato than the paste tomato I was expecting. Of all the plants, one of them is growing the cherry-like tomatoes, but has also set the more pepper-shaped opalka tomatoes I expected. Very strange.

    The taste is fine. They are dense like a paste, but the shape and size of a cherry tomato-not elongated, nor anywhere near 8 ounces.

    It’s as though they’re a hybrid. They are absolutely not the tomatoes they are supposed to be.

      Hi Sasha,

      Thank you for leaving your review about your experiences with the tomatoes. I’m so sorry you’re not getting the tomato crop you expected.

      The whole growing experience seems to be quite bizarre. When you were describing the tomatoes as cherry-like then my mind went to either a) you somehow received the wrong seeds or b) cross-pollination had caused a hybrid.

      Both these things are unlikely but possible events. But describing seeing Opalka and cherry-like tomatoes on the same plant is a true curiosity. If it was a genetic issue (wrong seeds or accidental hybrid) then the genes would express pretty uniformly on the same plant. With different types of shaped fruits, I wonder if it is a phenotype trait that you are experiencing. Perhaps different water or nutrients or temperatures have caused stunted tomato growth in some fruits.

      This is just open-minded ideas to try and troubleshoot the possible problems. Being agriculture, there is a good chance we’ll never work out what’s going on! I’d be extremely interested in seeing some pictures and in your continued observations, to see if later fruit mature more normally. We’ll also check with our tomato farmer to see if they have any experience with this.
