Bagged dead tree

A Bagged dead tree can be bought in Falador from the Garden supplier for 1000 coins or at the Grand Exchange. They can be planted in the garden of your Player-owned house if you have a Construction level of 5 or higher, providing 31 experience to both your Construction and Farming skills, but you cannot chop it down. It is only decoration. This item is also used when building a Volcanic habitat in the menagerie of a Player-owned house.

NOTE: that this item is now unavailable at the Grand Exchange

Trivia

 * Strangely, even though it is a "dead" tree, the seedling is green, and it is able to be planted and grown.
