Kentucky Pink Stamper Tomato Review & Photos: A Potato Leaf Giant

Share your rating
🍅 Quick take: Kentucky Pink Stamper is an indeterminate potato leaf (PL) heirloom from the US. Brought over to Russia by seed collectors, it pumps out massive pink beefsteaks (regularly breaking the 1 lb / 500 g mark) with distinctive pleated shoulders. While the fruit size and flavor are awesome, growers note that yields can be just average, and the thin skin makes it prone to cracking. Full summary ↓

Kentucky Pink Stamper. I grew this one from V. Redko’s seed stock. His catalog description reads: “Tall vine, PL, mid-season. Fruits are large, raspberry pink, gathered at the top like a little pouch (pleated shoulders), with really good flavor. Weight runs 1.1 lbs (500 g) and up. All meat, very few seeds in the fruit, sweet, and a heavy producer.”

Mid-season indet. I ran it to two leaders and ended up topping the vine at about 6.5 ft (2 m) tall.
Yield was just average for me. Some of the fruits cracked a little bit, and I never got more than three tomatoes per cluster.
The flavor is good, with a nice old-school acidic tang. Just lacked a tiny bit of sweetness for my taste.
If I give it another run, I’ll definitely prune it down to a single leader.

Full Summary: Plant, Yield, Taste and Flaws

  • 🌿 Plant: Indeterminate vine. Mid-season. Features large Potato Leaf (PL) foliage. Grows vigorously, easily reaching 6.5 ft (2 m) before needing to be topped.
  • 📈 Yield: Rated as average. It tends to set only 2-3 massive fruits per truss. Growers recommend pruning strictly to a single stem (leader) to maximize fruit size and plant energy.
  • 👅 Taste & Texture: Good, old-fashioned sweet and tart flavor. The flesh is incredibly meaty with very few seeds.
  • 🍅 Fruit Size: Giant raspberry-pink beefsteaks. Standard weight runs 1.1 lbs (500 g) and up. The fruits have a distinct shape, featuring ribbed, gathered shoulders that look like a tied pouch.
  • 🛡️ Drawbacks: Prone to splitting and concentric cracking around the stem, likely due to the thin skin and massive size.

👨‍🌾 Editor’s Note: Topping Tomatoes
In this thread, you’ll see a reference to “topping” the vine. In regions with short growing seasons (like the Moscow area), it is standard practice to chop the top off an indeterminate vine about 30 days before the first expected frost. This stops new vertical growth and forces the plant to put all its remaining energy into ripening the giant fruits already hanging on the lower clusters.
