Kosovo Heirloom Tomato Reviews & Photos: Giant Pink Oxheart

Rate this

📌 Quick Summary (TL;DR): Kosovo

  • 🌍 Origin: A world-famous heirloom whose seeds were originally brought to the US by a former U.N. worker returning from Kosovo. It is now widely grown and loved globally, including by Eastern European collectors.
  • 🌿 Plant Habit: Indeterminate (tall), easily reaching up to 8.2 feet (2.5 m). It displays classic oxheart traits: the vines are slender, and the foliage is very wispy, weeping, and looks somewhat frail (even though the plant is incredibly vigorous).
  • 🍅 Fruit Characteristics: Massive, beautiful pink hearts. They usually weigh around 10-18 oz (300-500 g), but frequently push 2 lbs (900 g) under good conditions. The skin is very thin and delicate.
  • 👅 Flavor: Pure, old-fashioned sugary sweetness. It is incredibly meaty but very juicy, meaning it practically melts in your mouth. Pro Tip: Because of its thin skin and delicate, juicy flesh, it has a very short shelf life. Eat it fresh or juice it immediately!

Please tell me more about this variety. There is barely any information about it on the internet. What did you like so much about it that made you include it in our 2013 grow-out experiment? 🤔

I’m curious too.

This is the only thing I found about it:

Height up to 8.2 feet (2.5 m). Weight 1 to 2 lbs (500-900 g).

There was also a photo or a drawing on that site. I managed to copy it through some unimaginable computer magic, but I can’t figure out how to paste it here. Looks beautiful from the picture.

Here is what someone wrote about Kosovo on another forum. Seems like this variety really rubbed the author the wrong way… 😂

“Here is what I love about Americans – they know how to package a story beautifully. Either a variety was lost forever but miraculously found on the wild shores of the Mississippi. And the guy who found it was unbelievably happy, but the tomato was even happier to be found, and rewarded this jungle-explorer handsomely. Or it’s a terribly rare variety (even though a tomato isn’t a palm tree, it grows in a year and produces an absolute mountain of seeds, but hey, it’s rare by definition because it just has to be) that was seemingly lost forever. But it was found by some completely impoverished comrade in an abandoned garden. And the overjoyed plant struck gold for its new owner, making him a millionaire. Where all the other gardeners were during this time is a mystery. Who he sold the tomatoes to for a million bucks is also hard to imagine. Why his competitors just walked around begging the lucky guy for seeds instead of just scooping seeds out of one single tomato is totally unclear. But… anyway, it happened. After reading revelations like this, you just want to drop everything and run to buy all the seeds of varieties with such a tragic, difficult destiny. And here you go. A father brought it out of Kosovo during a mission. I mean, they literally had to wait for an active warzone just to go fetch a tomato. Because before that, no American comrade had ever set foot in Kosovo. Long story short, he saved the tomato, carrying it out from under enemy fire.”

I actually noticed a long time ago that all American heirlooms seem to have a “tragic destiny” and it sent me into deep thought… but hey, who am I to judge.. 🤐

Alyonushka, it feels like everything about Kosovo has already been said here, I don’t know what else to add. And I think I already posted my personal photos on the other forum. But I only have photos of it when it was green. If I had known it was going to be part of an experiment, I would have taken a hundred pictures of it! But I didn’t know back then, so I didn’t bother. 👍

Lord, the photos you posted look very familiar to me, those are from Tatiana’s site 😉

As many people as there are, there are that many opinions. It performs differently for everyone, just like with any other tomato variety. Depends on where the seeds are from, where it’s grown, and who is growing it. People have been growing it since 2005. The Poles are already doing this with it: http://forumogrodnicze.info/viewtopic.php?p=2817166#p2817166

Lord, thanks for the photo collection (seeing these for the first time)!

When they are green, the shape really reminds me of “Mazarini”. And the vines are just as frail-looking.

They remind me of “Rozoviy Myod” (Pink Honey) too… 😵

I’m also really curious to see how it performs for you guys (in different regions) since the seeds were all taken from this exact same plant. Not all the tomatoes were 18 oz (500 g) of course, but the fruits definitely didn’t get smaller on the upper trusses, that’s for sure 😉

Natasha, sites usually list the days starting from when you transplant the seedlings into the ground 🙁 It’s really not that early. 🤐 More like a late-season variety.

Thanks girls 😳

For me it wasn’t super early, but it wasn’t extremely late either. I also got Hungarian Heart and Bull’s Heart from them, and out of those three, Kosovo was the first one to start ripening 😉

I don’t think it will store very long.. it’s a very delicate, tender tomato, makes incredibly delicious juice.

Thanks, girls. I got it. As usual, all the tasty, meaty ones don’t store well. And vice versa, the thick-skinned tomatoes store forever, but the taste is just whatever. I want a variety that has all the best traits at once. I guess those just don’t exist. 🙁

Ladoga (Anzhela) ⭐ Pro Grower (1,816 posts)

My Kosovo produced beautiful heart-shaped fruits with very few seeds, and a pretty decent yield for my growing conditions. But the inside was full of hard white veins, and closer to the stem it was completely white and hard. Maybe this variety just isn’t suited for our climate, or maybe that’s just its reaction to the massive temperature swings. But I really have no desire to grow it again.

I have a specific list of varieties that I plant every single year. They are my “magic wands”, so to speak. Thanks to them, I’m never left without a harvest.

Kosovo is on that exact list. I looked at the previous photo and got upset. That has never happened to me. Kosovo is an absolute workhorse variety. It loads up so heavily with fruit that it takes two people just to tie the vine up. Very tasty beefsteaks/hearts. I definitely recommend it.

Kosovo is an indet, the vine is slender and the foliage is wispy. Mid-season maturity. Fruits are large pink hearts, 12 oz (350 g) and up. The flesh is pink, tender, and looks sugary when you break it open. It’s a tomato meant for salads and canning where you need a lot of tomato “meat”. The skin is thin.

Vele: “What a beauty! Olya, what dominates the flavor profile, is it sweetness or tang?”

I classify these as sugar-sweet – the sweet taste definitely dominates. Sometimes it’s almost a bit mild or bland because there is so little acidity. A lot of it depends on the summer – how much sun and rain it gets.

👨‍🌾 Editor’s Note: The “American Heirloom” Rant

Early in the thread, a Russian user makes a hilarious, sarcastic rant about how Americans love to package heirloom seeds with dramatic backstories (“saved from a warzone,” “made a guy a millionaire”). This is actually a direct reference to the true origin of the Kosovo tomato, which was brought to the US by a former U.N. worker returning from the Kosovo conflict!
