It is possible to be unsuccessful when planting the seed, prompting the following message: "You planted the seed incorrectly in the fertile soil". The chance of this happening is dependent on the player's herblore level.^{[1]}. Once the tree has grown the player can cut a Yommi totem from it. Three seeds are obtained from Ungadulu at a time. If the seeds are lost or planted incorrectly, one can ask Ungadulu for three more. The seeds require level 45 Herblore to plant. The tree grows at an amazing rate, but can be cut only with a rune axe, and must be cut quickly so as to prevent it from getting rotten. The seeds have an identical inventory icon to mithril seeds.
