Waldo, Happy Thanksgiving!
Fair question, the comment you're referring to however is not on the HL itself, it is in the link to Hugo Philips' site
. Hugo collects the comments he shows from various commercial sites offering the plant in question for sale, there's no real way of attributing the comment in question to anyone in particular. Having said that, Hugo contributed one of the pictures shown for Quill and it might be an idea to contact him, however there is no contact link on his website. Contact me via private message and I'll see if I can find a current e-mail address for him, the only one I have right now is from 2009 and quite possibly no longer valid.
