Lepidozamia peroffskyana
Lepidozamia peroffskyana is a large Cycad that is endemic to Australia .
Some more info here: http://www.pacsoa.org.au/cycads/Lepidoz ... kyana.html
Seeds, ( will give them a 24hr soak and then into the propagator )

As these continue to germinate, a series cracks will develop on the seed end. The radicle will eventually push through at this point.

Barb, Thanks for the comments! Seems the majority germinate in this fashion, ( except for Cycas, which does the "clam shell" thing

new resolution for 2008, I am not going to germinate or purchase anything I can not pronounce. Starting with Lepidozamia Peroffskyana.
Serioulsy, nice work Steve. You keep us all honest with your passion for germinating, growing and teaching us all about plants from around the world. Thanks.
Please keep up the good work.

Thanks Kent! I can't pronounce it either
Maybe I have too much time on my hands, but it is still fun, and the learning is always ongoing.

Moistue levels .....
Ideally the top of the seed, ( where it sprouts ), is out of the germination mix and dry.
And enough moisture left in the mix to discolor the bottom. This seems to work well for the larger Cycad seeds.

Barb,
I am following Mr.Broome's example by keeping the sprouting end out of the medium, except for the Zamias, mine are germinated in containers and then potted up when the cotylendon is about 1/2" long.
Here is a link to the article: http://www.plantapalm.com/vce/horticulture/seeds.htm

Thanks for that link.
Tom Broome sure has published some very informative stuff.
Great that he's eliminating the guesswork on these valuable cycads for novices like me.
Especially good to read this one before my C.debaoensis seeds arrive...
Good luck with yours Steve (as though you need LUCK!!)

Hi Barb,
I'm not sure of the exact terminology, here are some photos to show the differences.
With Cycas seeds, this is the end that was attached to the cone. The scar is from where it detached. (usually the pointed end)
The other end will open in a clam shell fashion to allow the radicle to emerge, (as germination progresses, you will first notice the seams become evident, then eventually, the seed will split and open)
Here are some on their way
Other Cycad seeds have a spot in the shell that will weaken and push out as the radicle emerges.
This is where the radicle will emerge on a Encephalartos hildebrandtii seed.
This is the end that was attached to the cone,
This Lepidozamia peroffskyana is in progress,
And here is the end that was attached to the cone,

Steve, fab photos! Thanks for taking them.
I don't have my camera today, but the reason I asked is on my C.deboaensis seeds, for example, the
pronounced fine-pointed end I've stuck a bit into the soil/perlite.
The other end with its scars is pointed up a bit.
Here's an excerpt from Tom Broome's "how to optimize cycad seed germination" (I hope it's OK to print verbatim re copyright)!
There are two ends of a cycad seed. There is the end where the seed will sprout from and the end where the seed was attached to the cone (called the chalazal end). This end will usually have some sort of scar on it. The pattern of scars will vary depending on the genus and even the species in some cases. The sprouting end will usually have either a single spot on the end, a raised area, or as with Encephalartos seeds, a series of cracks that act as a hatch when the seed sprouts. I have found that placing the chalazal end down into the medium keeps the seed moist enough to make sure they don't go bad. This also means that the sprouting end is out of the medium and makes it very hard for fungus to enter the seed like it would if it was placed in the medium. . .
So...my pointy end...where the seed will sprout from, is not the end where the seed was attached because those scars are on the other end. And I've put the pointy end INTO THE MEDIUM, the opposite of what Tom seems to be advising.
I hope I'll find out when mine start to pop.
Note I said WHEN, not IF.
If the "clamshell" splits are at the scar end, I've done it right.
Thanks again for the super pics.

Barb,
Thanks for the comments! Haven't had the opportunity to try Cycas debaoensis, so I may not be much help on identifying which end is which (maybe someone with more experience will chime in)
Anyways, if in doubt, just place them on their sides about half way into the medium.
Once they germinate, you can let me know which end is which ( and don't forget the photos

That'll be a beauty indeed.
Look what it'll grow into

From all reports, it'll be impossible to give this too much water!

A year!
No wonder they're rare...those of us without necessary germination skills have given up.
This'll be a stunning plant.
Look forward to all your pictures.

Hi Barb,
All that's really neccesary is a sterile germination media, and patience!
These have been slow for me, but I'm sure somewhere they grow like weeds
