Obtaining and eating the Roda Tree Seed is one of the key elements to obtaining the Silver Sword. In order to actually talk to the trees so that they will give you the sword, Adol has to give the Silver harmonica to Lair so that she will wake the twin trees. At this point, Adol must talk to the tree by the Abandoned Mine. This Roda Tree will tell you to go see the other Roda Tree. At the second Roda tree the sword will be given to Adol .
