Minecraft sunflower plains seed 1.8.3 by desert and savanna
Here's an interesting one, this is a Minecraft 1.8.3 sunflower plains seed right at the spawn. It's really interesting, it's literally just a small patch of sunflower plains in the middle of nowhere. There are savanna nearby, as well as desert. There are two desert temples nearby and between them both are 6 diamonds and an enchanting book of unbreaking III. This is hands down one of the best Minecraft seeds.
The seed is: 3250098471810679850
On this Minecraft seed the coordinates of the first temple are x-225 z250 and the second temple is at x0 z-200 and is across the water. There's even a mushroom island somewhere nearby if you're willing to travel far enough. This seed is compatible as a Minecraft 1.8.4 plains seed as well.
Overall this is a really fun Minecraft 1.8.3 sunflower seed with tons of exploring to be done. With all the sunflowers in this biome there won't be any shortage of fresh sunflower seeds.
