Throw a Seed Index & Collection Guide
Fill the Index from Common to Secret with smarter throws, seeds, and Update 1 chase targets.
The Index is Throw a Seed’s long-term collection book: 75+ plants across ten rarities from Common to Secret, plus mutations and oversized specimens that turn a filled page into a flex. Fish Time Studios calls out Index completion in the Roblox description for a reason—throwing only for today’s cash leaves half the fantasy unfinished. This guide shows how to progress the Index without bankrupting your garden or ignoring strength.
Read this alongside Mutations & Secrets, Zones and Luck, the Plants Tier List, and Update 1 when new rarities and Secrets drop.
What the Index actually tracks
Think of the Index as a checklist of plant identities you have discovered, not merely what sits in your garden right now:
- Base plants by rarity band — Common through Secret across the launch pool.
- Update expansions — Update 1 adds two rarities and four Secrets, which deepen the Index ceiling during the November 13–20, 2026 window and beyond.
- Visual variants — mutations and huge sizes often matter for flex and income even when the base species is already checked off.
Opening the Index early—right after your first session in Getting Started—teaches you which bands you have never seen. That knowledge decides whether your next purchase should be a linear seed, a Seed Pack, or more training.
Collection vs income: do both on purpose
New players treat Index and garden as rivals. They are partners:
- Garden income funds the throws that fill the Index (Garden Income).
- Index discoveries reveal which rarities are worth keeping planted versus sold as fillers.
- Secrets and mutations can be both Index trophies and top earners—rank them on the Plants Tier List.
A practical split: keep your highest measured earners planted, rotate chase slots for missing Index bands, and sell true duplicates that do not help cash or collection. During Update 1, reserve at least one slot mindset for the four new Secrets instead of carpeting Commons.
How plants enter the Index
Plants appear when seeds land with enough luck. Luck rises when throws travel farther through the 15 zones from Meadow to Starlight Glade. That means Index progress is mostly a distance problem dressed as a collection problem.
Stack these levers:
- Timing skill — clean releases from How to Throw.
- Strength and bars — pull-ups and Wood→Diamond upgrades from Training Strength.
- Seed quality — shop tiers and event Seed Packs ranked on the Seeds Tier List.
- Volume of good throws — twenty Mid-zone landings beat two Meadow panic throws for new Index rolls.
Free gifts and daily rewards fund those levers; codes sometimes grant seeds that unlock new Index lines immediately.
Rarity roadmap for collectors
Use bands, not panic shopping:
| Phase | Focus | Index goal |
|---|---|---|
| Hour 1–3 | Consistent Mid-zone throws, full garden | Fill Common/Uncommon pages while learning timing |
| Early midgame | Strength + seed upgrade | Rare/Epic bands start appearing regularly |
| Midgame | Starlight-direction distance, mutation awareness | Legendary-adjacent bands and first mutation flexes |
| Update 1 / late | Seed Packs, new worlds, Secret hunting | Two new rarities + four Secrets + remaining Secrets |
If a band is empty, do not blame “bad RNG” until your average landing zone and seed tier match that band’s expectations. Recheck Zones and Luck.
Secrets, mutations, and Index flex
Secrets are the 1-in-a-million fantasy. They need stacked luck: distance, seed quality, and patience. Update 1’s four new Secrets raise the Index endgame and the screenshot meta in tiny lobbies (Players).
Mutations and huge sizes multiply garden value and often show as distinct Index or collection flair. Farm them after your base bands are mostly filled so you are not starving cash. Full tactics live on Mutations & Secrets.
Seed Packs as collection tools
Linear shop seeds raise baseline luck. Seed Packs (featured in Update 1) are collection accelerators when descriptions highlight missing rarities or Secrets. Open packs when:
- Garden capacity can accept winners immediately
- Strength already reaches the zones those packs expect
- You are missing specific Index bands the pack advertises
Blind-opening every pack while slots are full of Commons wastes both cash and collection potential. Track opens against the Progression Checklist.
Session checklist for Index hunters
- Claim daily rewards and any codes.
- Note which Index bands are empty before you spend.
- Train enough that throws can reach the zones those bands need.
- Equip the best justified seed—not always the newest hype seed.
- Throw for distance; log new discoveries in the Index UI.
- Plant keepers, sell fillers, expand capacity if chase plants have nowhere to live.
- During Update 1, prioritize world/pack lanes that name Secrets you lack.

Frequently Asked Questions
Quick answers for Throw a Seed players.
How many plants are in the Throw a Seed Index?
The game advertises 75+ plants across ten rarities from Common to Secret. Update 1 adds more rarities and four Secrets on top of that baseline.
Do I need every plant planted to complete the Index?
The Index tracks discovery and collection progress. Keep top earners planted, rotate chase slots for missing bands, and sell fillers that help neither cash nor Index.
Why am I not finding rare Index entries?
Luck scales with throw distance through fifteen zones. Improve timing, strength, and seed quality before assuming the Index is broken.
Are Seed Packs good for Index completion?
Yes when you have capacity and strength ready, and when packs target rarities or Secrets you still lack—especially during Update 1.
Should I prioritize Index or garden cash first?
Fund a stable garden first so throws stay financed, then dedicate sessions to missing Index bands. Secrets can serve both goals when they are strong earners.
