For almost 10 years I've been using the "Loco" spelling, which is also the way the name is spelled on HMF.com.

I've now changed the spelling to 'Koko Loko' in our database because a new forum member has pointed out that the "Loko" spelling is used by most retailers, including Weeks, and this is a Weeks rose.

I don't remember this kind of controversy over any other trademarked rose name.
