Spring, and the Synandrospadix are blooming ...
From: Steve Marak <samarak at arachne.uark.edu> on 1998.03.25 at 17:28:45(1982)|
And therefore time for my annual Synandrospadix post.
This year I am particularly interested in information on pollination and
self-compatibility of Synandrospadix, as I have two inflorescences. One
has just opened, the other should open within the next day or so. These
are on two offsets of the same clone, hence the self-compatibility
Also, has anyone else done any testing of the hardiness of this plant?
Since my plant forms offsets slowly (as in 1 each year, maybe 2 in a good
year), I put one outside in 1996. Unfortunately, it was not a good test -
while the tuber survived the winter without any sign of rot, it was
damaged by "itchy finger blight" in the spring, so I've no idea if the
climate or my impatience killed it.
Can anyone offer advice?

Last year I pollinated a Gorgonidium, which may be a lesson for
Synandrospadix too. Take pollen of the oldest inflor as soon as it is
released. Then open the other one (provided is is already well-developed
but still closed) by cutting away the entire spathe and brush the pollen
on the stigmas of that second one. Then wait....................
My Gorgonidium produced a huge and spectacular fruiting cone with deep
purple berries but the seeds were sort of semi-aborted.

Good to hear someone else grows this beaut. plant.
I am in temperate zone 9 so I don't know if it will help but my plant
( in a pot ) grows happily through spring and summer then seems to
thrive on a dry winter rest. I don't re-water until I see the first shoots.
I think the dry cold is the important bit.
Grown from seed in July '96 it took 3 months to germinate outside in
temps. 6 - 20 C. It has 2 large leaves now but I am not expecting a
flower for a couple of years.
How long did yours take to flower ?
Two years ago I emailed Eduardo in Brazil to quizz him on this Sth.
He told me it grows from low elevation up to 1500 m, can cope with
cold winters and 40 C summers. It flowers from Oct. - Dec. and fruits
in Feb. It is dormant in the cold , dry winter ( May - Sept. ).
Any more information I have forgotten Eduardo ?
Melbourne is having a cool / mild autumn, a welcome relief from
summer. It still will not rain though. Eduardo will you please take
back your El Nino !
The Arums and Biarums are flowering and Dracunculus canariensis and
Ambrosinia bassii are shooting like crazy.
Hope your spring has sprung.

It certainly is a beautiful plant. Mine came from Tom Croat at MoBot, and
flowered the following spring, so I don't really know how old it was, or
if it was a seed-grown plant or an offset. (I'm sure Tom has that
information; maybe I should dig out the accession number.)
As I say, it offsets regularly if slowly, which I'm told may be unusual
behavior for the species.
I'm curious as to how many clones are in cultivation and how widely they
vary in provenance. I'm also interested in getting another clone myself,
especially from whatever area may experience the coldest winter
temperatures, but this does not seem to be an easy plant to come by - not
many people are growing it. If it is an infrequent offsetter, this may be
cause and effect.
I also grow mine very dry during the winter rest - as close to no water at
all as I can get until I see growth in the spring. It will do quite well
in the greenhouse all year, but I intend to move it outside after frost
danger has passed for some stronger light this year. In my climate, this
means it will get some of those +40 C temperatures you mention.
We get the majority of our rain during winter, which may make establishing
it outdoors here hard even if it should prove technically hardy. That's a
big problem for us with many western US natives.

No, you didnt forget anything, Rob! I must add an important information.
The plant can cope with a wide range of temperature, but I dont think it
can grow in a substrate with bad drainage. With the exception of Gearum
brasiliense and Spathicarpa lanceolata (that are seasonal
water-dwellers), the other Spathicarpeae (like Synandropadix) are always
found in well-drained soil. If any of you are willing to grow it on the
floor, it is better to put the plant in a slope or provide an
extra-drainage in the beds.

Man, here in Brazil the weather is absolutely crazy. We are having an
ultra-hot and ultra-rainy autumn. Yesterday night, the rain was so
strong that some tubers was unpotted! (Better say: the tubers still was
in their pots, but the soil was out). No thanks, we already have Ninos
