TheWildRose.org was purchased on February 7, 2005. This was my first domain, and will probably be my last and only one, as I really don't need any more than that, since this serves all my needs, and I'm happy with it. :)
The name was inspired by the Nick Cave and Kylie Minogue song, Where The Wild Roses Grow, and since it's my absolute favorite song, I got the domain name in honor of that! I also just really like the sound of it.
ETA: I did get a second domain after all, and I had it for a few years, but I never did anything with it, so I let it go, and now I really don't see myself buying more than that!
