Auguste's sapling

Auguste's sapling is given during the Enlightened Journey quest by Auguste to grow into a willow tree in order to obtain willow branches to build the basket of the balloon for the Balloon transport system. The branches can be cut off any willow tree or bought on the Grand exchange. If you somehow lose it or the tree dies it is advised to buy the branches or another willow seed off the grand exchange as this is much cheaper than the 30k that Auguste will charge.
