Nonna Antonina. Seeds from Nadyusha in Kaluga Region. 💐

The flesh is just mouthwatering, true old-school tomato flavor! 🤤 Long, extended harvest window, and all the fruits stayed consistently large right to the end. 👍 Ran it both in open ground and in the greenhouse. Outdoors in the garden bed, production was actually noticeably higher.

Really loved Nonna Antonina! It’s a relatively modest, well-behaved plant that doesn’t get unruly or take over the patch, yet it loaded up with lots of large, bright red fruits. Fantastic flavor.

Turned out late in the season, but that was actually a big plus, it stepped right in for fresh salads after the main harvest rush, right when folks are usually burnt out on tomatoes))) Seeds came from a collector in Yoshkar-Ola. Definite keeper!

Full Summary: Plant Habit, Yield and Flavor Profile

  • 🌿 Plant & Heritage: Traditional Italian family heirloom featuring indeterminate vines with regular foliage. Demonstrates a remarkably polite, manageable growth habit that does not produce excessive runaway vegetative suckers, making it easy to stake and maintain.
  • 📈 Yield & Season: Late-season maturity with an extended fruiting period. Consistently maintains large beefsteak fruit size from first cluster to the final fall picks. Outperformed in open-ground garden beds compared to covered greenhouse trials.
  • 👅 Flavor Profile: Bold, rich, and deeply savory classic Italian tomato flavor with high juice content and firm, meaty flesh. Ideal for fresh summer salads and thick sandwich slices.
  • 🌎 Who Reviewed It: Three experienced growers spanning wide climate extremes: Tomatanya in cool northwestern Leningrad (Zone 5), azure in the temperate Don River region (Zone 7), and Lvovna in warm coastal Yalta (Zone 9).
