📌 Quick Summary (TL;DR): Amurskiy Shtamb (Amur Dwarf)
- 🌍 Origin: A rugged commercial variety bred by the Russian seed company “SeDeK”. Named after the Amur River region in the Russian Far East, an area known for its harsh climate. “Shtamb” means it is a “tree-type” dwarf plant.
- 🌿 Plant Habit: Determinate, tree-type dwarf. Reaches only 45-50 cm (18-20 inches) in height. It has a very thick, sturdy main stem and large, dark green rugose (crinkly) leaves. Requires absolutely no pruning or suckering.
- 🍅 Fruit Characteristics: Red, oblate (flattened globe) tomatoes with slight ribbing. For such a tiny plant, it produces surprisingly large fruits, often averaging 100-180g (3.5-6.5 oz), and sometimes up to 200g (7 oz).
- 👅 Flavor & Uses: An excellent early slicer with juicy, meaty flesh and classic tomato flavor.
- ❄️ Special Features: Exceptionally cold-tolerant. Designed for marginal farming zones with unpredictable weather. It is so vigorous that it can even be direct-seeded outdoors (without starting transplants indoors) in short-season climates. Verticillium wilt resistant.
