Stardew Fern

Overview

Stardew Fern is an herb crop in Starsand Island described in-game as "a fiddlehead fern with semi-transparent branches and leaves, said to be an ancient plant. Islanders love its soft and sticky texture." It becomes available once you earn the Expert Farmer certification from Graminova. Stardew Fern is one of the few crops that grows during all four seasons, making it a reliable income source year-round without worrying about seasonal transitions.

Each Stardew Fern plant takes 7 days and 18 hours to mature and produces 4 ferns per harvest. As an all-season Expert-tier crop, Stardew Fern offers strong profitability at roughly 160.3 gold per day. Its year-round availability is a major advantage over seasonal Expert crops like Chirpy Plum (Summer only) or Star Mango (Spring only). While some Expert crops earn more gold per day during their specific seasons, Stardew Fern generates consistent income during Winter and other off-seasons when most alternatives are unavailable.

Quick Stats

How to Obtain Seeds

Stardew Fern Seeds are purchased from the Happiness Seed Shop for 690g each after you reach the Expert Farmer tier. Since Stardew Fern is an all-season crop, the shop stocks its seeds at all times. You can buy and plant them in any season without waiting for a specific window.

You can also produce your own Stardew Fern Seeds using the Grinder, which converts harvested Stardew Fern back into seeds. The Grinder unlocks at the Senior Farmer tier, which you will have already passed by the time you reach Expert Farmer. Producing your own seeds eliminates the 690g purchase cost on subsequent planting cycles, which meaningfully improves your effective gold per day over time.

Growing Stardew Fern

Stardew Fern grows on regular tilled farmland or inside a Planting Box. It does not require a Trellis or Paddy Field. To plant Stardew Fern, till a plot of soil with your Hoe, select Stardew Fern Seeds from your inventory, and place them on the tilled tile. Alternatively, place them in a Planting Box if you prefer container farming.

Once planted, Stardew Fern takes 7 days and 18 hours (7.75 in-game days) to fully mature. You need to water it daily using your Watering Can, or set up sprinklers to automate the process. Because Stardew Fern grows in all four seasons, it will never wither from a season change. This is a significant advantage over seasonal crops, which die if they have not finished growing before the season ends.

Stardew Fern is a single-harvest crop. After you pick the 4 ferns, the plant is consumed and you must replant from seed. This differs from Trellis crops like Honeyvine or Star Plum that regrow after harvest. However, the all-season growing window means you can continuously replant without any downtime between seasons.

• Tip: With a 7.75-day growth cycle and roughly 28 days per season, you can fit about 3 full harvests per season. Across all four seasons, that amounts to roughly 12 or more harvests per in-game year.

• Tip: Use Yield Fertilizer to boost your harvest quantity beyond the base yield of 4. Stardew Fern is a high-value crop where each extra item is worth 483g, so Yield Fertilizer has a large payoff here.

• Tip: Place Bumblebee hives near your Stardew Fern fields. Bees boost crop growth speed, letting you squeeze in additional harvests and further improve your gold-per-day return.

Sell Prices

The base sell price for Stardew Fern is 483g per unit. Since each harvest produces 4 ferns, a single harvest sells for 1,932g at base quality. Higher-quality Stardew Fern sells for more. Quality is influenced by the fertilizer you use and random chance during growth.

You can sell Stardew Fern at Zerine's General Store at the prices listed below. For even higher returns, sell to the Merchant Ship when it docks at Starsand Port every Monday, as it pays 200% of the normal sell price for all items.

Processing and Uses

Stardew Fern is classified as an Herb rather than a Vegetable or Fruit. Because of this, it cannot be processed into Vegetable Juice or Fruit Pulp at the Separator. There are currently no cooking recipes that call for Stardew Fern as an ingredient. Its primary value comes from direct sales rather than crafting or cooking.

Grinder (Seed Recovery)

The Grinder lets you convert harvested Stardew Fern back into Stardew Fern Seeds. Since the Grinder unlocks at the Senior Farmer tier and Stardew Fern requires Expert Farmer, you will already have access to the Grinder when you start growing this crop. Producing your own seeds eliminates the 690g purchase cost on every planting cycle. Given Stardew Fern's high seed cost relative to other crops, using the Grinder is especially valuable here.

Profitability Analysis

Stardew Fern is one of the stronger Expert Farmer crops in terms of consistent gold per day, primarily because it grows year-round. While some seasonal Expert crops may outperform it during their specific seasons, Stardew Fern never has a gap in production. For a full comparison across all tiers, see the Crop Profitability Rankings article.

Comparison With Other Expert Farmer Crops

The Expert Farmer tier offers many high-value crops. Below is how Stardew Fern compares to other Expert crops. Note that Stardew Fern's all-season availability gives it a unique advantage in sustained income.

Honeyvine and Star Plum are often considered the top Expert-tier crops thanks to their short 6-day growth cycles and regrowth as Trellis crops. However, both are limited to two seasons. Stardew Fern fills the gaps: during Winter, when most Expert crops cannot grow, Stardew Fern keeps your fields productive alongside Jadelume and Fluffbean. For players who want a low-maintenance year-round crop at the Expert tier, Stardew Fern is an excellent choice.

Merchant Ship Sales

The Merchant Ship pays 200% of normal sell price. A single Stardew Fern harvest sold to the Merchant Ship yields 3,864g (966g x 4) instead of 1,932g. After subtracting the 670g seed cost, that is 3,174g profit per harvest, or roughly 409.5 g/day. Timing your harvests to coincide with the ship's Monday visits can dramatically boost income. Since Stardew Fern grows year-round, you can target Merchant Ship sales in every season.

Everlasting Stardew Fern Seeds

Like all crops in Starsand Island, Stardew Fern has an everlasting seed variant. Everlasting Stardew Fern Seeds produce a plant that regrows after every harvest without needing to replant. This eliminates both the seed cost and the time spent tilling and planting, turning Stardew Fern into a fully passive income source.

Because Stardew Fern already grows in all four seasons, the Everlasting variant is particularly powerful. A regular Everlasting crop only regrows during its designated season, but since Stardew Fern has no seasonal restriction, an Everlasting Stardew Fern will produce harvests continuously throughout the entire year with no downtime.

There is also a rarer Immortal variant. For most crops, Immortal Seeds remove seasonal restrictions. Since Stardew Fern already grows year-round, the Immortal variant functions identically to the Everlasting variant in practice.

Methods for obtaining everlasting and immortal seeds include:

1. Mirthshroom Soup: Eating this soup grants the Creamy Seeds buff. While active, harvesting any crop has a chance to drop everlasting or immortal seeds. Stacking 5 soups maximizes the drop rate.

2. Eternal Blessings: A Workpedia skill available at the Senior Farmer tier. Provides a permanent passive chance to receive everlasting crops when harvesting. Can be upgraded with Starsand Points.

3. Treasure Chests: Found on the surface island and in the Moonlit Forest. Some chests contain everlasting or immortal seeds.

4. Islandpedia Rewards: Completing certain Islandpedia milestones rewards everlasting seeds.

If you dig up an everlasting or immortal crop with a pickaxe, the seed is refunded to your inventory. You never lose it, which lets you freely relocate crops as your farm layout evolves.

Gifting

Stardew Fern can be gifted to NPCs. The following preferences have been confirmed:

Since Graminova loves Stardew Fern, gifting him a few each visit is a convenient way to build friendship while shopping for seeds at the Happiness Seed Shop. Marston, Matilda, and Sagewood also love it, so keeping a small stockpile for gifting throughout the year is worthwhile.

Tips

• Stardew Fern's all-season growth is its biggest advantage. While other Expert crops sit idle during their off-seasons, Stardew Fern keeps producing. Use it as your baseline income crop and supplement with seasonal specialists like Honeyvine in Spring/Summer or Jadelume in Winter.

• The 7.75-day growth cycle means about 3 full harvests per 28-day season. Across an entire year of four seasons, that is roughly 12 to 14 harvests depending on planting timing.

• Selling to the Merchant Ship on Monday at 200% price is the single biggest profit multiplier. Stockpile Stardew Fern in a chest and sell the entire batch when the ship arrives. At 966g per fern, even a small stockpile yields substantial income.

• Use the Grinder to produce Stardew Fern Seeds from harvested crops instead of buying them. This saves 670g per planting cycle and is especially impactful for a crop you will be growing year-round.

• Stardew Fern is one of the best crops for Yield Fertilizer. Each additional fern from a boosted harvest is worth 483g. Even one extra fern per harvest adds up substantially over dozens of cycles throughout the year.

• Consider using sprinklers on your Stardew Fern fields. Automating watering saves daily effort, and by the Expert tier you should have access to upgraded sprinklers that cover a wide area.

• Everlasting Stardew Fern Seeds are among the most valuable everlasting seeds in the game because they produce harvests in every season. Prioritize obtaining them through Mirthshroom Soup buffs or the Eternal Blessings skill.

• Stardew Fern pairs well with other Expert crops in a diversified farm. Grow Honeyvine and Star Plum on Trellises, plant Exotic Egg in Planting Boxes, and fill the rest of your standard farmland with Stardew Fern for steady year-round income.
