You must evolve a Roselia to get a Roserade. You'll need a shiny stone to evolve her. ^^
in vien forest
catch a Roselia then evolve it with a leaf stone.
he's in the vien town forest
hes in the place where there is the river go up the river. then on the land go down and theres roserade its close by the cave regirock is in.
It is obtainable in vien forest near Regirocks area, but you can obtain Roserade in Vien Forest after you completed the quest "Roserade Red, Roserade Blue".
I rate it a 8\10 because my are all level 100
In the 2nd Pokemon Ranger game, you can't get a Roserade manually, but you can capture a Roselia and evolve it. go to the place where regirock is hiding and outside the cave PS:you cant evolve in Pokemon ranger person above me...
