I think it is good to know what materials you are using so you can tell people what it is, but if you find an interesting section of wood and aren't sure what kind it is, I think it's still fine to use it (but that's just my opinion).
I know that some people like to include imaginary items in their wand descriptions, such as unicorn hair and such. I don't do this because I like to give a real-life account of the materials used. If the end owner wishes to imagine such items exist within the wand, then I will leave it up to them to decide those things. As an artist I don't like to tell viewers of my work what they should imagine, feel, or see when they look at my work because I think the work itself should communicate this to them.
Sometimes I will include real items in the core, such as various herbs, resins, stones, and so forth which allegedly have magical properties according to some, but whether the owner believes these to be magical or not is up to them. Some of my wands have been bought for use in cosplay, others for use in magic ceremonies, and still others purely for display.
