Amethyst (Ametist) Tomato Review

Rate this

📌 Quick Summary (TL;DR): Ametist (Amethyst)

  • 🌍 Origin: A Russian heirloom tomato. The seeds in this thread originally came from the well-known Russian seed collector Tamara Yashchenko. The name translates to “Amethyst”.
  • 🌿 Plant Habit: Highly debated among growers! The original vendor describes it as indeterminate (tall), but many forum members report it acting more like a semi-determinate or determinate, staying under 3 feet (1m) outdoors, and only reaching 5 feet (1.5m) in a greenhouse. The foliage tends to be on the wispy/spindly side.
  • 🍅 Fruit Characteristics: Oblate, pinkish-red beefsteaks. While the vendor claims they reach 14-17 oz (400-500g), most growers report average weights closer to 7-12 oz (200-350g).
  • 👅 Flavor: Highly rated. The fruits are wonderfully meaty yet very juicy, with a really pleasant, well-balanced flavor.
  • Yield & Maturity: Rated as early to mid-season. Yields vary wildly depending on growing conditions—from just a few fruits per plant in low light or under hoops, to heavy yields (16+ fruits) in better conditions.

Got the seeds from Tamara Yashchenko.

Mid-season. Tall (indeterminate). Fruits are oblate, 14-17 oz (400-500g), pink-red, very tasty. Sets fruit in any weather. High yield.

I got about two or three fruits per truss, weighing around 7-12 oz (200-350 grams).

Hey ladies, could you please tell me about the yield and taste of this variety? 🌺

I’m planning to add it to my grow list this year.

The tomato is both meaty and juicy at the same time. Really pleasant eating quality. As for the yield, I mentioned in my first post: 2-3 fruits per truss. I only had three trusses total. It grew in an old greenhouse with low light.

I grew it outdoors under low tunnels (hoops). The plant was wimpy and small. Yield was low. 2-3 fruits, just like mentioned above, and they weren’t big either. BUT it was early and very tasty.

My yield was actually really good—about 16 fruits on the plant, and I liked the taste a lot.
