What is confirmed
The official Roblox description says players buy a seed from the river, plant it in a plot, watch a tree grow, and harvest it before lightning strikes.
Greedy Growers Seed Tier List
A seed tier list is not available yet because no attributable source lists seed names, tiers, harvest values, or roles for this exact Roblox experience.
What is not published
Seed names, rarities, prices, harvest values, lightning effects, and best-seed rankings are not verified. This page will not invent them.
When rankings can appear
A creator-owned source or reproducible in-game data must identify the seed and the comparison criteria first.
