You can buy seeds in skyvale from one of the vendors.

They unlock over time. You probably need to continue the story.

Put it in a keg and sell the wine. Without any bonuses, that will sell for 2250 which is enough to buy 5 seeds. The best you can get from seed maker is 3. I think you'll on average make/save more money even selling the fruit unprocessed, especially if you have the Tiller profession and/or it has higher than normal quality, but I'm not 100% sure about that. But it's a bit of a gamble. With the seed maker, you might get 3 seeds in which case it's a win unless it was a gold quality fruit and you have tiller, but the seed maker might also give you one seed in which case it's a clear loss, and possibly mixed seeds which is a loss etc.

I planted all my ancient fruits in greenhouse and I fill all the farm in ginger island with starfruits, then turn them into wine and place them in kegs.

I like to make a point of saving all my first harvests for the seedmaker. But I make a fair substitute of gold from fishing.

I've planted ancient fruit in spring and it didn't even give anything yet

Starfruit are awesome if you have the greenhouse. Otherwise, turn it into wine and ship it off.

Seed Makers aren't worth it here. You'd need to sacrifice half your crop to replant with an average of 2 seeds produced per fruit.

That means you either convert one starfruit into a wine worth 2250g/3150g or two seeds worth 800g. That's a loss of 1450g/2350g per fruit.

The only situation where this would be profitable was if you were selling unprocessed fruit without the profession bonus, and then only fir regular quality.

My advice is use ancient fruit, I’ve done the calculations. It is better, and some people will argue that starfruit is better because when the kegs are done, you can put it in another starfruit, but my rebuttal to that is just make more kegs.

Seed makers aren't ever worth it except for ancient fruit IMO. Especially since all high value crops are worth more than twice the price of the seeds.

Buy seeds. One starfruit wine will net 3,150g, and you can buy 7 seeds+. In average, you will get 2 seeds out of one starfruit from a seed maker.

Get a lot of cranberries or blueberries and spam the seed makers ur gonna get one in a few stardew valley days

You can find the ancient seed artifact or get them from the seed maker (2% chance I believe)

If you're lucky the travelling cart might also have them

Hunt bugs at 15th and 25th floor in the mine. Within 1-3 days, you should get at least one.

Bugs and fishing is the best way. I kinda like fishing because I can get some more artifacts, not just the Seed!

Kumiromi's apostle can generate rainbow fruit seeds with its special ability.

They take 8 fertility, compared to grapes 5 and berry's 1. But they are quite good.

I've had the Kumiromi pet fairy for quite a while. The only time she produced rainbow fruit seeds is if I left her at base and adventured without her. If I let her join I get nothing even after she eats.

Rainbow fruit seeds come exclusively from Kumiromi's apostle, it's a chance to spawn whenever you feed him

If you dont know, they take alot of fertility. In my opinion they are only viable in a tent.

Do they not turn yellow when ripe? I could never grow these because I live in a place with like 4 months of winter, but the ones I sometimes see at the grocery store tend to be very yellow!

I love starfruit so much!

Blandfruits grow only on the bushes, which you can find in the secret "grill" room and occasionally in the shaded garden room, So yeah, they're rare, I seldom find more than 2 in a walkthrough

Barren land prevents their spawning if you have that on

They’re pretty uncommon, you can go multiple runs without seeing them and sometimes you’ll find three in a run instead.

If you’re lucky enough to get three starflower seeds you can just cook them into an experience potion for the same effect if you didn’t already know, blandfruit just saves you two seeds compared to making a potion.

I feel for you 😭 the amount of times I've accidentally done this and have gotten mixed seeds with starfruit and ancient fruit is pretty embarrassing.

I used to think it was my save file luck RNG until multiple save files did it... Now I know I am cursed. 😭😂

Are you able to go buy some from the shop in the oasis in the desert??

I’ve said it before and I’ll it again, restarting the day is NOT cheating

It's ok

You can just buy it from desert. No biggie.

OOF! thats probaly a profit loss hope the mixed seeds grow into something decent lol

How can you cheat in a game that is single player and has a playstyle of whatever you feel like?

If that happened to me with my luck i'd get a parsnip lol

My preferred method is to kill grubs in the mines. Take the elevator to floor 25, kill any grubs you see, then go back up to 0 to reset it. Should be able to get a seed in a few days doing that

There’s a like 1% chance to get it from the seed maker iirc (which you get from level 9 farming)

The most reliable method is to build a lot of seed makers and churn a lot of crops through them. It's expensive, but it works.

You can put common mushrooms from the mushroom cave into seed makers. Otherwise, hops and blueberries are good for producing a lot of individual crops quickly.

I've had good luck in the sewers, where all the bugs and fiber spawn.

You can also get them from artifact troves, which you can get from the desert trader.

I think fishing. I got mine really early on my hyper-efficient play through. In early game you can get the most money from fishing in order to buy strawberries. I think I was like lvl 9 fishing by the spring festival and I think I got an ancient seed before that.

It all boils down to luck. The other place to get it is farming bugs, but that’s gonna take some time to build up combat skills/weapons/energy/mining/hp
