Arisaema Sikokianum

[ellen&dan]

A. wallichianum is a lovely Arisaema.  Thats what makes collecting wild seeds so much fun, waiting for it to flower and seeing what you get.

Johan,
If you see no germination the first season it may be because the seed may be from a species such as Arisaema urashima. Such species don't produce an eophyll the first year, instead they just form a tuber.

David,

Yes, I have heard about some species behaving that way. I will keep the seed boxes for at least another year and just hope for a delayed germination.

Is there anyone who know wich Arisaema species that behave in this way?

John,

Keep them for a few years.  I've had germination of one species at least 3 years after sowing them.  I never throw out seed pots for a few years anyway, because you never can tell when the conditions will be "just right" for whatever it is to germinate.  One year I had Trillium seed germinate very well.... in pots that were 2, 3 or 4 years old.  All chose the same year to germinate as the conditions were obviously spot on that year.

That is an amazing tray of seedlings (you sure that it is not lettuce ). I sow my smaller quantities of seed in a small square pot and am delighted to see one seed germinate. The rest are a bonus. Good luck with them.

Paul,

I will keep my seed pots for a few more years, thats for sure. It is really hard to throw away any of the seed boxes, especialy the ones wich I have collected the seeds myself. I will probobly keep those boxes forever  !

I cant wait til spring, to se what will germinate for me. This is what makes sowing so fantastic. -As long as you have seed boxes around, it could be christmas any day!

David,


Normaly I dont sow that amount of seeds. and nomaly I dont have that kind of luck. I guess that every single seed must have germinated in that box.

We grow a lot of Arisaemas in the nurery where I work, so some of the bulbs will eventually end up there.

The last cuple of days I have gone through about ten different first year old Arisaema seedlings. ANd I find it amazing how big the differenses are between different species. And that its also possible to see some of the species characters. The first one is A. sikkokianum. The other remain sp. the second picture is the one from the massive seed tray. I think that the last one could be A. nepentoides

Johan,

The other thing I have found is that if you haven't had germination after a few years you should disturb the pot.  In the past I've had Fritillarias for example that have had germination over a couple of seasons, then I have ended up taking out the larger bulbs after about 3 years..... then I get more germination the following spring.  I know for absolute sure that it has happened with a couple of different Fritillarias, and an Erythronium, at the very least.  There is something about the disturbance that stimulates the remaining seeds to germinate.  Worth giving it a try before considering throwing out a seed pot.

this autumn, I obtain seeds of Arisaema saxatile from mine. I will sow them immediatly to morrow. First trying

[Gerhard Raschun]

In my optinion it is very easy to raise A. sikokianum from seeds.The fist flowers appear in the second growing season !, but only male flowers.But it is very difficult to obtain seeds.Every year I pollinate my plants, the seed heads break down before seeds reach maturity.So I hope this year is a better one....

With other Arisaema species it needs 4 or 5 years for the first flowers.

Here I want show a manmade hybrid: A. serratum x A. sik.

Hello everyone

Does anybody have any tips on sowing & germinating Arisaema sikokianum seeds?

Kind regards

Mike

I just got some of these from the AGS seedex and I'm looking for the same advice. The site:

http://www.onrockgarden.com/

says:

A 2 8 * sow thinly; keep dry when dormant; do not move for 2 years

A  Sow @ 20C. Seed germinates within 3 months.

2  Requires darkness.

8 Pulpy coat inhibits germination. Remove by soaking and rinsing in clean water daily for 7 days. Discard water.

Mike, David, this thread was already in existence so I have moved your posts to it!

Results from my sowings.
More are germinating every few days too.
