I live for rose wood, and would love to make a wand of it, or buy a basic rod wand made of it so I can still make it my own, but I dont know how to find it. XD
You might go to a horticultural garden and ask for prunings from a rosewood tree, not the same as a common garden flowering bush, but an endangered and over harvested tree, loved for it's scent.
I once tried to make my own from a stout rose bush cane. It wasn't pretty.
I always just pick up wood I find on walks... Never know what kind it is though, I wish I did. My favorite wand is made from a piece of wood I found on a beach. It's white, soft, and very light. Also, I like free stuff. Lol.
