Poison Ivy

Overview

A cheap-in-Robux Legendary with good value density. A common first premium purchase.

Poison Ivy is a Legendary, multi-harvest crop obtained from Robux / Seed Shop. Its base sell value at 1 kg is 1,700 Sheckles — and because value scales with weight squared, growing it heavier is the single biggest lever on your profit.

Poison Ivy in depth

Poison Ivy is a cheap-in-Robux Legendary with good value density at a 1,700 base value, which makes it a common first premium purchase. At just 99 Robux it is one of the most accessible ways to spend a little real currency for a meaningful jump in earning power over your starter crops.

It is multi-harvest, so it benefits fully from mutations — a single good roll keeps paying across every regrowth. Plant a row under a sprinkler while you save toward Mythic and Super seeds, and use the calculator to see how much a Rainbow roll adds before you commit your best weather window to it.

How to grow it well

• Buy the seed from robux / seed shop.
• Use higher-tier sprinklers to raise size luck — heavier crops are worth far more thanks to the weight-squared scaling.
• Being multi-harvest, it keeps producing, so it earns back a big mutation many times over.
• Chase a high Rainbow or event mutation on it — see the full mutation list for what each multiplier is worth.
• Protect it before night — other players can steal crops from unguarded gardens.
