No offence intended.... but would it be possible for you to please modify
the information you've put up on the wiki re the two Pinellias.  Yes, you
mention eventually that they are a problem for you just in the middle US,
but that is after warning people to never plant, avoid at all costs, "You
have been warned" and the like.  Your experiences are not a true "blanket"
statement for the species you mention?  The way you've written it you seem
to say that your experiences as guaranteed for everyone apparently, even
with the qualifier later in the paragraph that it is just your own area.
It just isn't true!!  Mentioning that it is weedy for you is fair enough
but warning people off it like you have is to me a gross representation of
the species (in fact any species any of us grow) which is why I am
"standing up" for it. <grin>

I am in a mild climate and I have yet to have problems with either of the
species you mention, despite seeing numerous diatribes to warn me off them.
 True, I would hesitate to grow them in the ground in an unsupervised
location, but warning people off them totally is a tad too extreme for what
is supposed to be a global collection of plants.  A bit of attention to
deadheading and the like, or growing them in a pot situation would bipass
most of the weediness in many locations, and there are some people who
can't even grow them if they try (and if they read the wiki at the moment
they certainly wouldn't give it a try out for themselves in their area

Personally I find that P. tripartita is comparatively far more of a worry
to me, but the seedlings are very easily pulled out and a large pot of
tripartita looks quite stunning when in flower, particularly the variety
'Atropurpurea' which has the purple interior to the flower.  

P. pedatissecta for me grows reasonably, but has seeded very moderately and
has barely multiplied as a plant at all. To be honest I wish I had more of
it as I am finding it quite slow growing.  If I read your paragraph on the
wiki I would have concluded that it was a pest to everyone and not to grow
it.  DEFINITELY not the case for me.

P. ternata has multiplied moderately and is unfortunately fairly shy to
flower for me.  It produces some bulbils and they do grow, but certainly
not the terror that I have heard about it in emails at various times.  I'm
just thankful I didn't listen to the original warnings and actually tried
it for myself.

Another in the genus, P. cordata, is very well behaved as I think it is for
most people, despite the fact that it produces a bulbil on each leaf.....
for some reason few of these seem to survive.  The wonderfully marbled
leaves look a little like some sort of miniature caladium or the like and
the little purplish flowers are delightfully delicate.

Unfortunately I've never been able to source any other species/varieties of
Pinellia as unlike you I would jump at the chance of trying them as I find
them rather intriguing little (in most cases) plants and I would like more.
 Hearing at times about differing forms of caudata has my collecting
addiction kicking in, but they aren't likely to be here in Aus I would
imagine and I don't know which "variety" the one I grow is.

I hope I am not alone in standing up for a much maligned genus, but all the
problems that I hear of them certainly have not yet occurred for me, and I
am in the mild climates that these "terrors" are supposed to grow so well
in. It's just a matter of pulling a few easily identifiable weeds out (the
first leaves of very distinctive), and the ocassional deadheading of a
plant to limit seeding.  I'd best stop there as this is already a long
enough email, but I did want to make sure that people realised that these
plants were NOT a problem everywhere, but could become a problem in SOME

If any of you have read this far thanks for taking the time to read
this..... I hope you try Pinellia and see what you think of them.  I
certainly have never regretted doing so!!
