That is one breathtaking collection! Ceroxylon is such a nice genus. Take some pics of your babies too.

Regards,

Milos

[richnorm]

Very nice,

I think maybe your parvifrons is vogelianum as the leaves look to be heading irregular.

[NApalm]

I'm really just getting into these. Great genus

[Gtlevine]

Nice collection, you have the best ones.

[Justin]

Cool! What's your maximum temperature during the summer?

[Pedro 65]

Ceroxylons Luis, how old are the Vents and Quins since germination ? 5 to 6 yrs ?

I have been aware of these for a year or 2 now but they are still quite new too me, I have a big interest in them also!!

Great collection there so far Luis, please update this thread in the future for us.

[LilikoiLee]

I hove this genus but alas, they don't like our climate and elevation......so really enjoyed seeing (and drooling over) yours.

I envy you, I can not grow successfully a single one in my climate with very hot summer.

[Ben in Norcal]

I envy you, I can not grow successfully a single one in my climate with very hot summer.

Have you tried Amazonicum? I am trying that here.

[Mauna Kea Cloudforest]

I am growing:

• c. alpinum (difficult to get to 5g size, rots easily)
• c. amazonicum (very easy)
• c. parvifrons (very easy)
• c. quindiuense (very easy)
• c. vogelanium (very easy)
• c. echinatum (least sun tolerant early on)
• c. ventricosum (very easy)

i have a bunch in the ground, but I keep at least 10-20 specimens going in my nursery to replace marginals.

The only thing that limits growth for me is water. I get the bulk of growth when the ground is wet from rains.

[Mauna Kea Cloudforest]

I'll pass along four tips for how to grow these:

1) Over the years, I noticed that the ratio of roots to top growth is horrible, meaning these things produce way too much top growth as seedlings for the amount of roots they have. Sorta the opposite of a brahea or a bentinckia. This is probably the number one reason they're difficult in a hot dry Summer climate. They just don't have the root mass to support a lot of drought or heat stress. Canopy is critical for these in hotter climates.

2) It's tempting to transplant them into larger containers early when you see that they have a lot of top growth, but they do best in a 1 gallon pot until they're totally rootbound in there. At that point, they're ready to go into the ground. They will usually have generated a good 2 feet of top growth by then.

3) The other problem is fungus. They don't do well at all in stagnant air. It's tempting to place them in a protected spot where there is a lot of shade, but if there's no air flow, they will get fungal rot in heart beat. A preventative fungicide usually helps. For me, this is the most problematic. My Summers are very humid, and I tend to loose more to fungus than anything else.

4) These palms have delicious palm hearts that voles will devour overnight. Since they bury themselves into the ground, it makes them particularly susceptible to the voles. I lost three large specimens that way before I adopted two vicious feral cats that have decimated to voles.

[Darold Petty]

I concur with Axel's observations in post #13. Especially about the disproportionate size of the top growth relative to the roots. A common error is to move them up to a larger pot based on the top growth. However, there is not sufficient root mass to knit together the pot medium. When the plant is removed from the pot the medium will just fall apart, damaging the roots and fine root hairs. (I have learned this the hard way, through direct experience, )

[LUSITANIA/PALMS]

Hi

Seeds are purchased in rps,how ever the germinate was using the climate(not electric devices)cold greenhouse,where they grew the first years all ceroxylon.

-ceroxylon quindiuense

- 30 seeds,in sand=stone undone mechanically,more efficient to accumulate humidity than the river.

-germinate 24 seeds (2008)in the first year was dead three seedling.

-after emerging the first leaf, I have transplanted to a pot(1.5 L,5 L,15L,only sand+soil of my garden)all Ceroxylon never fertilized !

Enemies in greenhouse-red mites,mealybugs ,summer(the warmest days 39celcius)one black fungus associated with the substance that produce the mealybugs(?),direct sun.

Enemies in outdor-direct sun,hot days+warm nights+low humidity,heavy frost(climates where not prosper Archontophoenix cunninghamiana,forget, lose your time).

[mike in kurtistown]

A question for those who germinated their Ceroxylons from seed - how long did they take to germinate? Is it possible for a young tree to produce full-size seeds that are not viable?

[Darold Petty]

Mike, I don't have written records of germination elapsed period, but memory says 4-8 months. Ceroxylon is a dioecious genus, so one plant is not happening, seed-wise. And yes, palms can occasionally make 'dummy' seeds. Sometimes I see this in Chamaedorea.

[LUSITANIA/PALMS]

HI

-Some days can reach 35celcius but the normal is 23,24,25celcius.

-theCeroxylon quindiuense germinated in 2007 (order 10seeds)and 2008 (order 20seeds)

-ceroxylon ventricosum, germinated in 2006,time to germinated 70 days,10 seeds,germinated four.

-yes,I have you tried Amazonicum,outdoor in pots below big palms,no damage in first winter,passed the test.

-Medium time to germinated all ceroxylon 90 day(my experience)

The seeds that were sold by RPS in 2010 as c.parvifrons are not c.vogelianum as you can see in the photos, but those were sold in 2009 (?) Seem c.vogelianum(?)(one could only buy small amounts)

ceroxylon parvifrons (seeds 2010)The time will tell, but if they are not, then we were all fooled by the outside world !

I know well the c.vogelianum, slow to split the leaves, but when they do it,in two or three leaves have plumose leaves .

-left c.vogelianum right c.parvifrons(seeds 2010)

c.vogelianum

c.parvifrons(seeds 2010)

Thanks

Excellent work. Your records are interesting!

So this one is from 2009 seed? So far they appear to be a very attractive palm down here but get a lot of scale on the petioles.

hi,2010,I Buy seeds in two sellers,but appears, they came from the same seed supplier!

Yes, seed sometimes does the rounds! I may be wrong, and often am, but suspect that plant is also an impostor! Bit early to be sure. On the plus side they are very attractive and distinctive as young plants and hopefully will continue to look good as they gain size.

[tbearz]

Here is one of the parvifrons I've grown from the 2010 RPS seed. It looks a bit different from my more mature parvifrons, but it is still small. It has been in the ground for two summers now - I'm in San Francisco. I had about 7 germinate and the other ones have been given away. One I gave to my neighbor and it is just 25 yards from this one and is already going pinnate. It gets a bit more sun.

Hi,have a good color,the color is like that of the two elements-aerial/soil

Sure wish that Ceroxylon could survive here.

So am I, but it's soooooo slow here in interior NorCal. I'm expecting it may croak next year if it doesn't produce more leaves. Also waiting to see if any of the Ceroxylon sasaimae seeds I got via RPS will sprout this year.

[Alberto]

Parabéns! Nice collection. I also have some of them growing here.

Why is ceroxylon never mentioned for the gulf south US? Too hot? Too humid?

My understanding is the humidity. Several of them are quite cold hardy too.

They require cool summer nights and cool to mild days to grow well. They grow very well in San Francisco and much of the Bay Area as well as the central and southern CA coastal areas. I have several species in my Los Altos garden up to fifteen years old. No trunks yet but lots of lush top growth. Hot humid summer areas are their worst enemies.

Unfortunately I have to agree. My Ceroxylon quindiuense seedlings couldn't make it here. Our summers are too long with temps around 30C/86F day and night for 

about eight months in a row.

A great species, @LUSITANIA/PALMS all the best for your awesome collection!

Well, there you have it. Thanks guys. Looks like we are just limited in a warm temperate climate in our palm choices..... eliminate about 5 days of cold per year and I could grow probably hundreds more species. Same lament I’ve seen repeated on these forums but just wanted to say it again.
