Quick answer
I canvassed the internet, Google searched, AI summarized, deep dove into Reddit, and even asked my own community to find the craziest and sometime useful seeds that you need to try in Valheim. And these are just the minimum distances, so you may have to travel way farther than that. Both onion and turnup seeds are commonly difficult to find. Carrot seeds can be a bit difficult to find since they are not very common, only spawning in this biome.
Kale seeds are one of them. Birch seeds and acorns can now be planted to regrow the tree. At base level the scythe will allow you when swung to harvest crops and seeds within a 1.5 meter radius which increases to 2.5 meters at level 100. Chickens, or more accurately, hens will eat barley, dandelions, and also a range of seeds, including beach seeds, birch seeds, carrot seeds, turnip seeds, and onion seeds.
Kale, whose seeds can be picked from sprouts and can seemingly be planted and grown in most of Valheim's biomes. These provide turnup seeds, which are needed to grow turnipss used in some new recipes. Fifth, ivy seeds purchased can be planted and function like the vineberry seeds from the ashlands. They have a chance to contain a mountain chest with a bunch of awesome loot like obsidian and onion seeds used to grow onions.
Seed basics
Stop playing on seeds you hate Valheim is a procedurally generated game and what that means is that no world is exactly like any other. Search chests in ruins as unlike the black forest and swamp, onion seeds are found within chests and unlock much improved food recipes which will be critical for overcoming this biome. Like bosses, minibosses have a 100% drop rate so her trophy will be simple to acquire.And lastly, the Elder after summoning with 3 ancient seeds, again with a perfect drop rate. But after realizing that even if the turnups got done that I would have to replant them for more seeds, I just decided to go for bone mass with what I had.
Carry some ancient seeds to the altar. And to start things off, this seed probably has the craziest spawn I've ever seen, shared to me by Barefoot Cookie. So, it will be a while before you find its alt biomes. Onion seeds, for instance, can only be found in chests across the mountains overworld and come with a tiny loot chance of a mere 12 1/2% chance.
The good news is the Black Forest has everything you need to start producing bronze, so you can get your farm started pretty quickly, and you definitely should once you found carrot seeds. In most seeds in Valheim, you start very close to the world center, but this one flips that on its head. Now with the oat seeds, you can actually uh put these into the windmill. Its worth noting that that bonus resources will be rewarded from farming planted seeds, crops but also foraging mushrooms and berries in the wild as well.
How to use seeds
And third and fourth, pot eitr and oat seeds can only be found inside barrels at these specific storage huts, also containing the occasional weapon cast. I suggest trying to find onion seeds as fast as you can because onions are used in recipes to craft some powerful foods like onion soup only requiring three onions and providing a whopping 60 stamina. We're still on the hunt for onion seeds. Big shout out to her for finding this one.
And you can find these as early as 500 m from spawn. Turnup seeds, on the other hand, are not found in a chest, but rather growing in the swamp's biome. Onion seeds are more challenging to find because they require RNG. But, we'll get to some better seeds for that in a bit.
So, it's added in 10 of those oat seeds, and let's wait for them to process. The oat seeds in particular, like barley before them, must be ground up at a windmill for flour before unlocking all kinds of the Deep North food recipes. How many ivy seeds did I get? The mushroom variant, specifically, can also be found in the Black Forest.
Best seed choices
Here, you'll find yourself nearly 2,000 m from it, which has all kinds of complicating implications. With the swamp being covered with so much water, the turnup seeds spawn far less frequently than carrots in the Black Forest for comparison. And once you find the seeds, all three can be grown safely back at base. Of course, you will still need to sail to both the north and ashlands, but that's the case in all seeds.
And so, you see there, we processed the oat seeds into oats. Okay, we're going to drop the seeds for now. The birch, like previously, will consist of a normal Meadows, but with way more birch trees than normal, while small tree will be absolutely covered in saplings. To make matters worse, the three Eikthyr locations are nowhere near you, occurring again almost 2,000 m away.
If you're ever having trouble finding them, consider typing print seeds into your chat box. It might even be worth it to brave the deep north early on to see if you can quickly grab some kale seeds to take back to your farm. Of all the seeds I researched for this video, no other seed has all three so close together. On our walk, I encountered two new crops in lingan berries, kale, and kale seeds, which will undoubtedly be key ingredients in many of the foods that have been teased in previous blog posts.
Map tools
We're going to keep the seeds. For one, this is approximately the distance where swamps begin to appear in world generation, and despite it only being a small bit of coastline, you can basically see spiky swamp trees from the sacrificial stones. What's really interesting about these alt biomes is that many of them can overlap to make really wacky combinations. In fact, the Elder, Bonemass, and even Moder are all closer to your spawn than even Eikthyr.
Maples, unlike other seasonal items, can occur naturally on some seeds in Meadows villages, but it's not guaranteed, making it one of the most elusive items in the game. Of all all seeds I came across, this one has the closest tetra location, except maybe one of the seeds with a huge mountain that we'll get to shortly. You can also encounter this alt biome type in the Plains. So, admittedly, all the attributes of the seed are negative and probably only useful for a challenge style run.
In Valheim, there is a master seed in which all other seeds are derived. Next, at 1,000 m, you can find peaceful Meadows that will likely make for the optimal base location. None have Eikthyr, any wooden structures, almost nothing to speak of. And again, this is an oversimplification of the process, but can explain why you may encounter similar shaped landmasses on completely different and unique seeds.
Tips
What's special about this one is that it blocks 11 other hostile creatures from spawning. Although, you can't forget the limits of building around the sacrificial stones due to those pesky magical forces, so space will be constrained. Even though it's the only seed I've ever seen remotely like it, so I had to share. Beyond that, occurring at 1900 m are the dark meadows.
If I had to pick my favorite, it would have to be this one for its surrounding larger ring-like landmass and small river outlet to the larger ocean. And speaking of challenges, these next three fall into a very similar category, offering very limited resources, and the third one offering even more. Here you'll find Draugr villages predominantly on lower terrain and have more hostile weather conditions. It has the same small challenging starting island, but beyond that offers all kinds of great base building opportunities throughout.
Each consists of the tiniest of starting islands, in fact, the smallest I could find in all my research. Best of them all at this distance are ruined black forest. These next two are for those looking to make Valheim's newest weapon, the early axes. Structure six on the other hand has a chest 100% of the time and has the same 55% chance of spawning the curious axe head.
