Fossil Fern
Fossil Fern is prehistoric event botany frozen in time — 91 Sheckles base on a special frond that pairs Ancient tags with mandrake-row aesthetics.
Base value
Fossil Fern base value is 91 Sheckles. At 7 kg, raw sell is 91 × 49 = 4,459 Sheckles. At 12 kg you reach 91 × 144 = 13,104 Sheckles — weight² dominates before growth mutations multiply the stack.
Mutations & weather
Prehistoric event crops pair with Ancient, Fossilized, and Amber tags when fossil weather overlaps. Golden growth remains reliable when event windows miss.
Farming loop
Plant fossil-fern at prehistoric event start so maturity overlaps peak event weather — shared event conditions boost proc rates on neighboring event crops. Clear Skies between events works for kg pushing without mutation chasing.
Fossil Fern strategy
Fossil Row Synergy
Fossil Fern belongs in prehistoric event rows with fossil-fern, tar-pit-tomato, and amber-fruit — Ancient and Fossilized tags proc more often when multiple prehistoric crops mature together.
Prehistoric event seeds cost more; set minimum kg in the calculator before planting fossil-fern so one bad weather week does not wipe the row profit.
Ancient Tag Discipline
At 91 base, primordial-vine and fossil-fern compete for slow plots — run both through the calculator at your actual mutation luck before committing.
Trade prehistoric harvests with event badge visible in screenshots. Collectors pay for provenance, not just mutation icons.
Common questions
- When should I plant Fossil Fern for the prehistoric event?
- At prehistoric event start so maturity overlaps peak weather. Off-event planting still works for kg — event tags proc mainly during active weeks.
- Is Fossil Fern worth mutating?
- Golden growth on heavy fossil-fern is fine for learning. Skip expensive env rerolls until you upgrade to higher base special crops.
