Marigold seed

A Marigold seed is used in the Farming skill to grow Marigolds. They can be planted in a flower patch, and requires level 2 Farming. When fully grown, it protects Potatoes, Onions and Tomatoes from disease.

Seeds can be purchased from Olivia's Draynor Seed Market for 84 coins. It is also a common Thieving item from Olivia's seed stall with a Thieving level 27, and it is also possible to pickpocket it from Master Farmers with level 38 Thieving.

It is a good idea to watch this patch frequently, as it gets diseased often.
