Where to find Oasis biome or feathercrown seeds

Im looking for feathercrown seeds the wiki refers to the oasis biome but i have been to over 30 desert planets and have not found one

 

Desert planets are what you want. Oasis biomes are more likely to be found on those than anywhere else.

You could also try to find an avian village and look for quests. When an NPC wants you to help them make a food item, they give you the seeds for the ingredients first. You might be able to find a quest that will give you feathercrown seeds.

 

Look, forget exploring, safest bet is Naturalist merchants who sometimes sell Feathercrown seeds amongst other seeds, place some Giant Flower furniture and Colony Deed in a room to spawn them.
And I'm pretty sure it's Colourful biome where Feathercrowns spawn naturally. Mistook with grapes. Still, looking for them is pain in the ass, merchant method is infinitely better.

 

which tier deserts do oasis spawn like dry grasslands, or just normal desert

 

thanks spawned a naturlist by placing 3 x giant plant chairs in a room he sold them

 

Wow thank you for the tip, I didn't know about the merchant selling seeds. Very useful
