I actually germinated ceroxylon parvifrons seeds

[happypalms]

I can’t believe I managed to get these ceroxylon seeds to germinat. I wasnt doubting the quality of seeds. I was more worried about my climate being to warm for once, pretty well much sown at the start of summer so my fear was was that I wasn’t going to be able to keep them cool enough to germinate. It was a long hot summer, so the seeds were kept inside on tile floor in the coolest part of the house. So nearly 6 months later they are a popping. Not sure what I will do with them I might have to send them to the polar bear growers down south!

Well done I got some quindiuense to sprout from the last RPS batch, I checked a couple of the parvifrons and found they had no embryo.

You might have to because mine are being very recalcitrant! I had them out in the shadehouse over summer assuming they'd like it cool, but maybe it was too cool. Got them on mid 20's in the propagator now, so hopefully something happens. Personally I blame Tim Brissy for sending me all the floaters!

Also...have never had problems germinating Ceroxylon species in the past, which is frustrating now that I've got seeds of the one I've always wanted...Bah Humbug!!

I have some of the same seed batch and they are germinating well.

About 50% to date. In a baggie outside in a shady spot here in NZ.

Excuses excuses, you polar bears need a a germinating lesson! But honestly would Tim our president of the southern palm mafia chapter send you the floater iam shocked at such accusations! I reckon it’s the happypalms knack!🤣🤣🤣🤣🤣

ps hopefully I can get a few to you

It seems they are a popular variety of palm, globally!

I do, I have!

The fact that he hasn't stepped up to defend his honour, seals his guilt.

Sorry mate, kept all the good ones for myself 😉

I have a question for you Australian friends, but does Ceroxylon grow in your area? Are there adult plants? Here in southern Europe they die in the summer due to the heat, I have tried 3/4 species, germination is easy

Hi Guiseppe. I’m not aware of any mature specimen in Melbourne, but that’s more due to their slow growth and relatively recent introduction to cultivation here I think. There are a number of long term survivors growing well including in my garden, but they need at least filtered light or shade when small. I think there may be a mature Ceroxylon alpinum in Sydney. 
 

I lost many seedlings years ago when temperatures got up to 46.4C but a Ceroxylon alpinum is still growing well today from that batch. Moisture and shade are important.

Next challenge for you will be keeping seedlings alive during next summer.

I have a theory, that if initial germination conditions (temp, substrate, moisture) are far from ideal beyond a certain limit, something occurs within the endosperm, which inhibits still alive  embryo to become active, it is something like a shielding.

Richard I'm sorry to say this, but we are here to share our experiences 

Konstantinos I totally agree
