Coccothrinax boschiana / Pseudophoenix ekmanii

Recommended Posts

Collected a few seeds from the palms we visited on a recent trip to the Dominican Republic.In less than 3 weeks,both of these species are already sprouting!

Fresh seed sure does have its advantages. :)

How did you go about germinating the pseudophoenix ekmanii, are they just thrown the ground?

Heck no! Everything is sterilized;water,soil,seeds,and containers. Propagation chambers are kept at 90F soil temp.Seeds are too rare to take chances with...When's the last time you ever saw Coccothrinax boschiana available;plants or seeds?

The habitat that these 2 species live in is soo remote,there is no other reason to be there other than to look at the trees.The small populations that only exist in these specific areas will still be safe for many years to come.

This is what our 4X4 rental car looked like after a car wash at the end of our trip.Pretty much totaled by rental standards. It only had 2 small scratches when we picked it up.We had to hire a paint shop to buff out the entire car before we could even THINK about trying to turn it back in...

Here is Coccothrinax boschiana, 7 weeks from sowing.Now the real challenge begins... (trying to grow them to 1 gallon size where they should be safe) If successful,I'll bring you one GMann.(figure about 4 or 5 years...) :)

Coccothrinax boschiana - planted the seeds almost 3 months ago.Between 1 and 2 inches tall at this point. Still going...

Very cool..  Do you keep the seeds under light?How about the ekmanii?

Seeds are now outdoors in a greenhouse. Pseudophoenix ekmanii seeds are much larger and are bigger,stronger,plants than the tiny seeds of Coccothrinax boschiana.

That’s awesome. I’ve read in the past the Dominican Republic has the highest auto accident fatality rate in the world. I’m sure the style/condition of roads factors in, granted you were in a remote location.

Roads are actually in as good a shape as ours in the USA. Problem is that most people seem to commute by moped and small motorcycle over there;swarming through,alongside,and in and out of traffic;always just inches away from becoming a fatality.Red lights and stop signs are merely taken as a suggestion as most people give 2 toots on the horn and plow on through.Seems there are no rules of the road,and nobody to enforce them if there were...

Some of the typical transportation used in the Dominican Republic.

That makes sense. How many Coccothrinax boschiana ended up germinating for you? Any idea on hardiness? Probably 30*F or slightly under?

I probably have at least 25 seeds germinated at this time. VERY delicate blades of grass now,best left in their germinating box.Tried transplanting 10 seeds shortly after they sprouted to individual pots and only have 3 of those surviving. These are remote germinaters and produce a 3" plus root out of their tiny seed, before any green shoot.

Next winter,I will experiment with hardiness.In their natural environment,they probably never see below 55F.Mature fronds are very stiff though, and should survive a light freeze.

Tried a few of the boschiana seeds in jiffy pots too.This was probably a better way to go to avoid root disturbance,but by the looks of things,as soon as I see a sprout,it is already ready for a 1 gallon pot! Seems like overkill to plant a bb sized seed with a 1/2mm sprout into that large a pot, but that is what the root system is screaming for.

Seeds are tiny! Only about 4mm wide each.

It might grow dramatically faster in a oversized container. I know certain palms wait to have a large stable root system before above ground growth takes off .

4 months out now from collecting and planting the seeds in a community pot.Like popping popcorn,germination seems to be about done.Time to pot up these seedlings with their giant root systems into individual 1 gallon pots! :)

Can't imagine how old those Pseudophoenix ekmanii  are.  Mine is about 2' tall after 20 years in the ground.  I'll admit it didn't get a lot of water or sun during those years.  Will try to remember to take a picture tomorrow.

Got it today.  I'm sitting at the same level as the palm.  22 years in the ground.

I’m sure in a lot of ways that’s extremely disappointing. Maybe increase watering?

That ekmanii doesn't look robust. Even the young plants are thick little palms. To me, it doesn't look like the species.

 They are slow, but not that slow. It should also have a thicker caliper and thicker, stiffer leaves.

Definitely an ekmanii.While other Pseudophoenix species grow reasonably well under desert conditions,ekmanii seems to be the exception.I grew a batch of these from seed and have trialed them under many different exposures around my yard with little success.Some die outright,some hang on and always look bad,and some plod on,growing only 1 new frond every two years.Here are a few pics of mine...

Plain old desert grown sargentii, on the other hand, can look as good as they do in Florida.

Yea I've abused it w/not enough water.

Seedling update... Typical examples of the seedlings,6 months after germination.

A planted ekmanii from a previous batch. Unfotunately,can't recommend this species for Arizona,although sister species sargentii is a definite winner here.

      Bought this one as a 15 gallon over a dozen years ago from Florida. Slow but steady... Over 12 ft tall overall now. I think it's established!
      Anybody else growing this species on the left coast? I know Mattyb has one...

      Here's a Pseudophoenix sargentii I grew from seed started about 20 years ago. They do well in the desert,but seem to grow much slower than under tropical conditions. Finally got it's first trunk ring,so growth should be speeding up at this point. I've grown dozens of this species and until a trunk is formed,I only get 1 new frond produced each year.After trunk formation,2 or 3 new fronds per year is the norm.

      I have been unable to find much info about this Coccothrinax from southern Cuba. Palmpedia says very little but lists it as a species. Another source I consulted indicated it might be a ssp of C. miraguama but says little else. I found the following info on PalmTalk:
      https://www.palmtalk.org/forum/index.php?/topic/40614-coccothrinax-cupularis/
      No matter, it's a great palm and uncommon in gardens. I planted my mother palm on my Garden Lot around 2012. It has been one of the fastest growing Coccothrinax I have despite receiving no supplemental irrigation. I estimate it is around 10' tall now. I germinated the plants for sale from her seeds and they are ~3 years old now with palmate leaves and sturdy stems. These are the only ones I have.

      Now that our temps have finally settled into the lower 100'sF in the Arizona desert, Caribbean species are starting to flower,en masse! First up is Pseudophoenix sargentii. (all pics taken just now)
