Dear Julius and all,

I first saw Philodendron 'Xanadu' as a photograph presented to me during my
tenure as a micropropagation production lab manager for the now dissolved
division of Weyerhaeuser
Tissue Culture back in the spring of 1987.  The Australian nurseryman
presenting the new cultivar was hoping that a large U.S. horticultural company
like Weyerhaeuser might be interested in producing and marketing  this unique
Philodendron.  It was nominated as the Australian Nurseryman's Association
Plant of the Year and it had received a good reception from the Australian
market.  I felt that the P. 'Xanadu' was a real winner for the US market as
well.   However, the upper management of Weyerhaeuser did not recognize the
potential of the plant and passed on the opportunity.

A couple of years later,  I know that Twyford Plant Laboratories
(http://www.twyford.com) did gain the U.S. patent for P. 'Xanadu' and have
been successfully producing the plant since then.  I contacted Beth Lamb, New
Products Development Manager of Twyford Plant Laboratories, about the origin
of P. 'Xanadu' and she asked that I pass along the following information to

I hope this helps shed some light on the enigmatic Philodendron 'Xanadu'.  I
will leave the nomenclature to Alistair and Wilbert, and the taxonomy to Tom.
By the way,  P. 'Xanadu' does just as well as P. selloum as a landscape plant
here in USDA Plant Hardiness Zone 7b, and is widely used as a landscape plant
at Disney as Lester Kallus has correctly observed.

Regards,  Scott
