Thrinax Questions

Hi,

I just bought a Thrinax (I knew I had remembered seeing them mentioned here.)

I was wondering about placement in the garden. After my Archonto C. fried right up in 112 heat, I don't want to place this one anywhere where it'll be unhappy.

Is full sun okay? or does it too need protection from afternoon sun?

Thanks! :)

Scott,

     Thrinax are very tough palms when it comes to heat. They love the full sun, and should do fine.

I've had some trouble with Thrinax during the winter.  None have died yet, but they don't seem to like the cold, wet soil too much.  I'd try to plant yours somewhere that's dry and sunny in the winter.

Scott:

I second Hoagie's advice.  I've got a couple and they don't look hot in the winter.  Cold and wet will do in a lot of tropical palms, which Thrinax are, though they will take a lot of cold, too, if properly planted and sited.

when you say "wet" conditions will do it in do you mean a lack of drainage,or extended periods of rain with cold

conditions?

Mine got hit with heavy frost this last february in my field.  They are full recovered now and actually did great through the dry spring.

Plant them in a fast draining spot with the most sun you can afford them.

They are great palms!!

Here is a multi radiata...

My garden is DG, which drains pretty well.  But, I am on a south facing foothill, so I average about twice as much rain as locations near the coast.  I think Thrinax just don't like the climate here in the winter.  Too much cold rain, not enough heat, even if the soil drains pretty well.  Next time I want to plant a Thrinax I think I'll go with a Trachycarpus instead....

Rob-

Did you notice a difference in hardiness between radiata, morrisii, and excelsa?

I am pretty sure that excelsa is not hardy.  I have mine in a very protected location.

None have damage from last February.  That was more of a frost event though.

I really like the excelsa.  The big floppy leaves are rather attractive.

There is one morrisii in the filed that saw 30 degrees or less.  It looks fine today.

Rob-

Its good to hear they all recovered.  Is it safe to assume that they all were damaged to various degrees?  If so, which fared best?

I am probing as I have a radiata and I am not sure what to expect!  I have always heard that radiata is a wimp compared to morrisii.  And, Ive always assumed that excelsa was more tender than radiata (perhaps incorrectly).

Kinda like both.  Get around by planting on a mound of sandy dirt . . . .

This past January we had two nights of 28 degrees with heavy frost. Of the three, Thrinax radiata showed the most damage, with most, if not all, leaves turning yellow and in some cases brown. The excelsa were only slightly damaged and the morrisii showed no damage at all.

They were all about the same size, 2-3 feet, and in 3 gallon pots and growing in adjacent beds of the nursery.

The radiata and excelsa have recovered but still have a few yellow leaves on the bottom.

Wow, alot of good info! Thanks!

Plenty of sun I have, but trying to keep it dry during the winter is the challenge. Dave, your idea of the mound sounds good. I have thick clay soil, and I heard that when you add sand, it becomes like a brick. Has anyone experienced this?

Your excelsa survived heavy frost?  I'm surprised - I'd heard that it was the most tender - glad that isn't the case.  Excelsa are beauties - among the fan palms, they're one of my favorites.  (and another thrinax goes on the wish list.)

Not surprised that the morrissii came through unscathed.  From everything I've heard, they're very tough.  (Also tough to find.  Grrr.)
