Radunitsa Tomato Review: A Sweet Orange Siberian Variety

Rate this

Quick Summary of Radunitsa

  • 🌍 Origin: A highly regarded commercial variety from the famous Russian seed company “Siberian Garden” (SibSad).
  • 🌿 Plant Habit: Highly versatile. It performs well in greenhouses, thrives outdoors in the open ground, and can even be successfully grown in a large pot (container gardening). Interestingly, growers report better yields outdoors than inside the greenhouse.
  • 🍅 Fruit Characteristics: Large, elongated orange fruits weighing 200-300 g (7-10.5 oz). They transition from yellow to a deep orange. The fruits have very thick walls, dense flesh, and a high dry matter content.
  • 👅 Flavor: Known for its high sugar levels. When left to hang on the vine until fully orange, they are exceptionally sweet and delicious—often compared to top-tier orange varieties like Zolotoy Königsberg and Yuzhnyi Zagar.
  • 🥫 Usage: A fantastic all-rounder. While delicious fresh, its meatiness and dense texture make it an absolute favorite for winter processing, sauces, and canning. It also boasts a very good shelf life.

Radunitsa. As the seed packet description says: “The fruits are distinguished by a high content of dry matter and sugars.” And yes, the tomato is indeed very tasty. Each truss holds several eye-pleasing fruits, and it is a very dense, meaty, and sweet tomato.

Because of these exact qualities, it became an absolute favorite for my winter canning and processing. It has reserved a permanent spot in my grow list for every single year.

I should also note that it sets fruit quite well (it only skipped a few blossoms on the third truss—so not a full cluster there in the greenhouse). It did great despite the fact that my second plant was growing outdoors in a standard pot right against the greenhouse wall. It also has a very good shelf life.

And here is how Radunitsa looked growing outdoors in the pot (photo taken July 2nd):

They are from “Siberian Garden” (SibSad), bought at a regular store.

I grew them both in the greenhouse and outdoors in the open ground. In the greenhouse, the yield turned out to be lower… only two to three fruits per truss. However, outdoors, the trusses held about 5 fruits each.

The fruits are very dense with thick walls. At first, they color up to yellow, but if you let them hang on the vine a bit longer, they turn a deep orange. At this stage, they are incredibly delicious—very similar to Zolotoy Königsberg and Yuzhnyi Zagar (Southern Tan). Weight is around 200-300 g (7-10.5 oz). Seeds were from SibSad.
