Quick Summary of Sladkoe Chudo (Sweet Miracle)
- 🌍 Origin: A highly prized Russian heirloom. The name translates to “Sweet Miracle.” Warning: This thread reveals that many commercial seed companies sell incorrect, off-type seeds under this name. The “true” variety described here was circulated among collectors (originating from N. Berezhnova).
- 🌿 Plant Habit: Indeterminate, reaching about 1.5 to 2 meters (5 to 6.5 ft) tall. It has classic oxheart traits: the plant footprint is very compact, and the foliage is quite “wispy” and delicate. Because of this, it requires full sun and good airflow—do not let it get shaded out by bushier plants.
- 🍅 Fruit Characteristics: Large, beautiful red hearts with slight ribbing. They are incredibly meaty and dense, containing almost no seeds. The average weight is around 400g (14 oz), but they can easily reach 500–800g (1.1–1.7 lbs).
- 👅 Flavor: Absolutely lives up to its name. It is exceptionally sweet, sugary, and rich, even late into the autumn season.
- 💡 The Seed Mystery: True Sweet Miracle is a tall, indeterminate red oxheart. If you buy commercial packets that claim it is a determinate bush, or if it produces small, flat-round tomatoes, you have a commercial fake!
A tall, indeterminate variety. The fruits are red, heart-shaped with slight ribbing, beautiful, meaty, and very sweet. In fact, it was the sweetest variety of my entire 2013 season (out of 90 varieties grown!). Even towards the end of summer and the beginning of autumn, the fruits didn’t lose their sweetness.
There are very few seeds inside the fruit. The stated potential weight is up to 800g (1.7 lbs). Mine grew outdoors in open ground, and the average fruit weight was 400 grams (14 oz). The fruits did not crack.
I pruned it to 2 stems. The yield was average, but purely because of the amazing sweet taste, I will definitely be repeating this variety.
Seeds were from collector N. Berezhnova.


Elena, I am planning to plant the seeds you sent me. Could you please tell me how many days it takes to mature? 📝
Wait, isn’t this just the variety “Market Miracle” (Chudo rynka)?
Girls, I grew “Market Miracle” from the commercial seed company Poisk, and it was garbage… It didn’t match the description at all, and it was just a really bad tomato overall.

Tatiana! I would classify it as a mid-season variety. I sowed the seeds on March 5th, and the first ripe red fruits were picked in early August.
I also want to add that the bushes did not suffer from any diseases at all, and I harvested the last fruits at the end of September (grown outdoors in open ground).
I bought this commercial packet, so I will plant it alongside the true seeds Elena sent me. It will be interesting to compare.
But looking at the packet, it looks flat-round, whereas Elena’s photos clearly show a heart shape… I don’t really understand, maybe I’ll end up with “Sweet Miracle #2” 😄
I’m also growing that one, plus another packet from Redko. The names are the same, but the descriptions are completely different. I will compare them.
Tatiana! I think I’ve seen that commercial packet in stores. Check the back—does it say it’s a determinate (bush) variety?
My true Sweet Miracle has very pronounced, obvious heart shapes, that’s for sure.

Here is exactly what the commercial website (Ural’skiy Dachnik) says:
“Large, sweet fruits containing a huge amount of sugar. The plant is determinate, requires no staking or pruning. Fruits are deep red, meaty, weighing up to 200g (7 oz). Resistant to a complex of diseases.”
Elena, was yours super sweet too?

The tastiest of them all! 👍👍👍
Something is wrong with mine. My “Miracle” is growing as a flat-round shape 😳 (Clearly an off-type).
Here is what my Sweet Miracle grew into.
But there were only two of them on the entire bush…
And when I cut it open, I found exactly 5 fully formed seeds in the whole thing…


Sweet Miracle turned out to be one of the absolute best varieties of this year! (I grew the true seeds sent by Elena, which originally came from N. Berezhnova).
The variety is delicious, sweet, and large. It didn’t throw any tantrums as a seedling, and it grew without any problems. It is an indeterminate, but it takes up very little horizontal space (compact footprint). Mid-season. Bright red color, and all the fruits are uniform and flawless.
You know how collectors will often throw around the phrase “Super Variety!”? Well, this one actually deserves that title!!!

But what grew out of the commercial packet you bought?
It seems like everyone is getting different things! Some have a pointy tip, some don’t, some have a dimple… Why are there so many differences? I was looking into this variety, but all this extreme variation worries me. Is it genetically unstable? Did someone dehybridize an F1 hybrid? Or did commercial companies just shove several different random varieties under one marketable name?
I kind of want to try it, but what will actually grow? It feels like a pure experiment at this point.

Nothing grew out of the commercial packet, because mice broke into the greenhouse in early spring and ate the seedlings! There was still snow outside the greenhouse, so the poor things probably had nothing else to eat.

Alena, if you stick around the tomato-growing community, you will realize that you are going to have a LOT of experiments, and they will never stop!!! 🌹

Alena! I am convinced that several completely different varieties have been shoved under one name by seed companies. Because the fruits people are showing are obviously completely different genetics. The true “Miracle” from Berezhnova has a very specific, delicate, wispy foliage plant structure. I don’t know what the commercial fakes look like.
Tatiana! I am so glad you loved the true Sweet Miracle! 👍🌹
A few more thoughts on Sweet Miracle.
Last year, I grew 2 plants outdoors in open ground—the yield was slightly above average, which I consider perfectly fine for a gourmet-tasting variety. This year, I grew one bush in the greenhouse (in the middle, slightly shaded) and one outdoors. The one in the shaded greenhouse only produced TWO tomatoes, while the outdoor one performed just as well as last year.
So, does this mean the variety is strictly for outdoors? Or does it mean that in a greenhouse, it needs to be planted in the absolute sunniest, most open spot because its wispy foliage structure can’t compete for light? It probably needs heavy feeding, too.
Regardless, it is staying on my favorites list for the second year in a row because it is sweet, meaty, and practically seedless.


I noticed the exact same behavior with the variety Southern Tan (Yuzhny Zagar). For some people, it sets fruit much better outdoors. If it’s in a greenhouse, it clearly needs a lot of personal space and light.

Elena, the seeds were from you, thank you! 🌹
Mine grew in the new greenhouse right by the aisle, pruned to two stems. The yield was normal—about 10 large hearts per plant 😉 It got lucky because almost nothing shaded it! 😄 Very meaty 👍, sweet 😋, with very few seeds.
I planted it in the summer of 2016, seeds from the commercial company “Ural’skiy Dachnik”. A real “miracle” alright… the plant grew 1.8m tall, sprawling, and produced exactly 4 fruits. The taste wasn’t sour, but it was incredibly bland, and definitely not sugary/sweet! (A classic commercial fake).
I grew 2 bushes of Sweet Miracle in a polycarbonate greenhouse—one pruned to two stems, the other to a single stem. The bush was very compact, not sprawling, 150 cm (5 ft) tall, took up very little space, and grew in the brightest spot. I didn’t weigh the fruits, but they looked to be well over 200-400 grams (7-14 oz).
On the multi-stemmed plant, there were 4 trusses holding 12 huge tomatoes. On the single-stem plant, there were 4 trusses holding 11 tomatoes. As soon as I harvested the first truss, the tomatoes on the upper trusses rapidly swelled up. I loved the taste—they weren’t watery; they were perfectly dense, full fruits.
The seeds were from Svetikk, for which I am incredibly grateful! This is exactly why I only get my seeds from collectors, never commercial packets!!!!

My Sweet Miracle looks more like a giant plum than a heart.. 😄 but it justifies the name—it is sweet and meaty..

My Sweet Miracle variety also turned out to have a more elongated shape. In the greenhouse, it reached about 2 meters (6.5 ft) tall. The taste was excellent, very sweet.


And here is the “Sweet Miracle” that I ended up with. It grew as a determinate (bush) instead of an indeterminate, and they were small! To be fair, they were actually tasty. Or maybe I just haven’t eaten truly delicious tomatoes yet.
In the photo, “Sweet Miracle” is the bush in the back—small round tomatoes, noticeably with green shoulders. I saved seeds from it just in case.
