Growers’ Notes and Photos (USDA Zones 4-6 Experience)
Indeterminate, mid-season, super productive and gorgeous variety. Out of all my bicolors, this was one of the first to ripen. Beefsteak fruits, a mix of gold, orange, and pink. Once they get overripe, they turn almost completely pink. Flavor is really good. Absolutely loved this one!
Elena, looks like a great one for folks who love a juicy, tasty tomato! How’s the shelf life? Also, do you know where it originally comes from and whose seeds you used? I’d probably call it Blush instead of Yellow… 😂
Zulfiya, the seeds were sent over from the States. As for storage, no clue. I juiced all my bicolors right away. But I wouldn’t say Hartsack goes bad fast.
I just really love bicolors for how pretty they are 👍

Elena, what a stunner! 📝
Gorgeous tomato 👍. Looks like it doesn’t crack either. I really love that fruit shape, and tasty on top of that, man… an absolute dream 🙂 😳
Ladies! I wouldn’t say the flavor will blow your mind, I’ve had better-tasting bicolors. But it really is very good, just a nice pleasant taste. The vine really stood out against everything else though—super bright, heavy yielder, didn’t drop any blossoms…
Svetlana! Good eye, the fruits don’t crack at all. Quick note for everyone 📝 – if you pull them green and ripen them indoors, they’ll just turn plain yellow.
Elena, is the flavor more on the tart side, sweetish, or just straight tomatoey?
Vera! Nah, definitely not just tomatoey. Complex flavor, got some sweetness and just a TINY bit of tartness. I’d call it balanced. But you probably know 😉 I rarely give a variety a 5/5. This year, out of my 500 plants (over 250 varieties), I only gave one single variety a solid 5 across the board.
Got it, thanks for the link…

Super showy plant, good flavor, juicy. Started ripening early. To me, the flavor didn’t really scream bicolor, just tasted like a really solid, delicious tomato. Here’s a pic from June 28. Didn’t drop a single truss (I had plenty of other varieties drop one or two). Hung on the vine forever without cracking. Early ones were smaller, then higher up they got about twice as big and flatter. Same vine a month later (we already ate the bottom ones 🙂), photo from July 27.
Just absolutely beautiful!
First ones to ripen were a bit smaller, but the rest were around 7 oz (200 g). Really dug that oblate shape 👍
First fruit is starting to blush on Hartsack Yellow.
All my other varieties are throwing massive fruits—except this one. The ripening tomato looks like it’ll top out at maybe 1.7 to 2.8 oz (50-80 g).
Aside from my cherries, I don’t have anything else this small 😠
Grew it this year. Seeds came from Nadezhda down in Volgograd (Nadin – huge thanks for the seeds 🙏). Only had one vine. Didn’t take any pictures this year.
The tomatoes are gorgeous. Perfectly uniform. First trusses were about 5 oz (150 g), higher up they hit 8.8-10.5 oz (250-300 g). Tasty. Juicy. No cracking. 👍
Husband liked them better than all the others we grew 😉
Full Summary: Hartsack Yellow
- 🌿 Plant: Indeterminate, mid-season vine. Highly reliable setter that doesn’t drop blossoms. Starts producing earlier than most other bicolors.
- 📈 Yield: Exceptionally high. Growers consistently praised it for out-producing other varieties.
- 👅 Taste: A complex, well-balanced flavor leaning toward the sweet side. Very juicy and meaty. It was a top pick for fresh eating and juicing, often winning over family members in taste tests.
- 📦 Storage: Doesn’t crack on the vine, even when left hanging for a long time. However, if picked green, it will ripen indoors to a solid yellow rather than developing the beautiful gold/orange/pink bicolor marbling.
- 🌎 Who Reviewed It: 5 growers across short-season and moderate climates (Zones 4-6) left detailed reviews, while several others chimed in to admire the photos.
