I've always been curious to see the different seeds rarities but it was never stated in-game directly. However, i've just remembered that there is a rarity filter which also affects seeds. Anyhow, this is what I came up with by examining it closely.

Pumpkin Seeds:100%

Dragonfruit: 60% (Common)
Luputus Tuber Seed:60% (Common)
Bearberry Seed: 60% (Common)
Mini Banana Seed:60% (Common)
Catnip Seed: 60% (Common)
Tricolor Flower Seed: 60% (Common)
Giant Clover Seed: 60% (Common)
Voxel Fruit Seed: 60% (Common)
Aloevera Seed: 60% (Common)
Blueberry Seed: 60% (Common)
Trinut Seed: 60% (Common)
DNA Beans Seed: 60% (Common)

Evolvulus Seed: 20% (Rare)
Evolution Fruit: 20% (Rare)

Lucid Evolvulus Seed 10% (Very Rare)
Devolution Fruit: 10% (Very Rare)

Anybody find similar findings?

I'm curious, too!!
I've been playing since xmas and I'm pretty sure I've only received lucid evo seeds once or twice from the lottery. (And I lotto every day because I have 3 first checks when my interactions become available, and lotto them first EVEN THO.... I want those pumpkin seeds hehe. I love familiar people and wanna help their pets )

Actually lucid , devolution fruit , evovulus flower , evolution fruit and tricolor flower plant seeds are all 20% rarity. I did test it to find the exact rarity of them back when rarity affect the max number a stack of item can be . Those seeds are always give me 2 seeds per stack with 100 slvl . And for tricolor flower seeds you can just sort by rarity in your inv bag for plant seeds and tricolor flowers will be in between of lucid and devolution plant seeds which mean same rarity of them . For other plant seeds they're all 60% rarity.

They do. I got 6 seeds stack on common seeds with lv 11 pet and 100 slvl. With lv 50 to 100 pets with 100 slvl I always get stack of 2 evovulus , devolution , lucid or evolution fruit seeds so I'm pretty sure they're same rarity.
