  New cultivated Philodendron.
From: "Julius Boos" ju-bo at msn.com> on 2003.01.08 at 16:50:01(9781)
Dear Friends,

In the December 2002, Vol. 11, No. 12 issue of "Ornamental Outlook Mag'.
there is a note on pg. 40, an announcement by Twyford Plant Labs on three
new 'ornamental' Aroid selections.---- " 'Showboat' is Twyford's latest
philodendron since its predecessor 'Xanadu'. With its larger, more deeply
lobed leaves and slightly larger growth habit, 'Showboat' is making an
impact in the interiorscape and foliage markets'.
[The other two aroids are 'Double Take', a short-statured Spathiphyllum for
us in smaller containers, and 'Tropic Fire', a Hawaii-bred Anthurium hybrid
somewhat like 'Lady Jane', but w/ radiant red spathes and a yellow spadix,
and is reportidly resistant to bacterial blight.]
There are color photos of these three plants, and Philo. 'Showboat' looks to
me like an aduly, older plant of P. 'Xanadu' that one sees in a garden that
is several years old. .If anyone has or can get information from Twyford
labs about the origin of the new Philodendron 'Showboat', is it another
'find' from somewhere beside Australia, or is it just an 'outtake' on
Xanadu, perhaps selected because of the slight differences seen from the
millions of tissue cultured plants of Xanadu?? Any information from
anyone with a contact at Twyford`s will be greatly appreciated.

Julius Boos.

Many thanks Julius for the info on new ornamental aroids. While on this
subject, I recently bought a very handsome specimen trained on a moss pole,
produced in the Netherlands and labelled Philodendron 'Cobra'. It has very
glossy, white-speckled, entire leaves, narrowly ovate, about 5-6 inches
long, with rounded, not pointed tips, winged petioles. The internodes are
short, so the foliage is nicely compact. I have never seen it before - but
then we probably have a smaller range of aroids sold as houseplants in
Europe that you do in the States. Any ideas of 'Cobra's origins? Before I
read the label I thought from a distance it looked like Monstera lechleriana
but with much narrower leaves. It's certainly one of the best-looking vining
aroids I have seen for a long time.

I also recently bought a vining Philodendron with no label - looks like P.
hederaceum (P. scandens) but has a yellowish band down each midrib. Does
anyone know the name of this cv?

Julius,

Have some of the philodendrons come from Australia? I am intrigued by your
reference to being "somewhere beside Australia" as I didn't realise that
some originated from here. I really don't know a great deal about the
tropical aroids, so I thought I'd take this opportunity to ask.

Thanks in anticipation.

Cheers.

Dear Paul,

Just to make it clear. There is no Philodendron that is really from
Australia. They are exclusively neotropical, occurring originally from
Argentina to Mexico. Anyhow, many interesting cultivars were selected there
in Australia (as well as in Florida), that?s what Julius was talking about.

Very best wishes,

Eduardo.

Dear Deni,

Well, this Philodendron hederaceum with yellowish band must be P.
hederaceum cv. "Brasil". In their book on ornamental plants in Brazil
(Lorenzi, H. & Souza, H.M. 2001. Plantas Ornamentais do Brasil, 3ed.
Instituto Plantarum de Estudos da Flora, Nova Odessa) the authors stated:
(here freely translated) "This cultivar were selected in Brazil by Ruben
Acosta. The cultivar `Aurea` with leaves completely yellowish... was the
starting point of the selection". It has became popular in Brazil because
green and yellow are the main national colors.

Very best wishes,

Eduardo.

Dear Paul,

There are no NATURALLY occuring Philodendrons in Australia, but many years
ago a couple that lived in Australia, the Winterbourns, claimed that a
single plant of a VERY distinctive Philodendron grew amongst a batch of P.
bipinn. ('selloum') seed, this single plant, with the 'help' of tissue
culture, has become perhaps the best-selling Aroid produced by tissue
culture, it is marketed as Philodendron Xanadu. There should be an
article in the next Aroideana about this plant, look out for it folks!

Good Growing,

Julius
