Ravenea xerophila

Recommended Posts

I have two 10 year old seedlings... one in the artic lawn where temps were probably pretty low (27F is the lowest I recorded, but this seedling is near a Trachycarpus latisectus that was defoliated, and a Trachycarpus martianus that was scorched significantlly)... one leaf did fold in on itself.  Later this leaf was lost, as was one other.  This plant has had frost on it 4x now this winter with no damage at all, but temps were not even 32F those nights.  There was no frost at all this night.

Turns out, from how things did in neighboring yards and from what little actual data was taken near me, that the edge of my yard may have gotten down to 24F... this palm is in the lowest spot at that edge.  Got more frost a month later and still looks great.  This is my vote for the hardiest of all the Raveneas!

The other seedling, a much larger and happier plant in a raised planter in back with the merest hint of overhead protection (a slatted overhang nearby) was not affected at all.

Yeah, Dave, I know the feeling,

I have two that probably took 25 F under lathe in Dec.  I moved them in my pool house for the Jan freeze.  One of mine is an overpotted 10 Gal size.  I think it's going in the ground this summer.  They are just to slow and rare to lose when they can be protected.  Only 32F here this morning, but more ice on my pool for the 3rd day in a row and a white frost.  Did any of you guys get frost on them?

I have many in the ground from seedling to seven foot plants, all cruised through the cold at 27F.

This is begining to sound interesting. R. xerophila may be the most cold hardy of the lot.  I definately will put one of mine in the ground this spring.  The problem is, I have no overhead protection where my cactus mound is and that is where it should go.....excellent drainage.  I need a fast growing small tree that will let in 50% light and not go decidious in the winter.  Any suggestions?

Sixty small 5 gal

19f, many hours and nights below freezing (field nursery)

3 dead, others still alive. Not sure how to judge if they're struggling, as they're so slow, anyway. But just the fact that they're alive is shocking.

If global warming means I can grow Cocos Nucifera, then bring it on....

26F and many hours and nights at or below freezing with many mornings with short periods of light frost. No damage on one gallon in ground plants.

Sounds like one with potential here.

My 5 year old rivularis specimens hang in there but they sure look bad every January through May (unprotected).

One glauca with partial cover doesn't look too bad now.

I'm going to try some xerophila seeds this year - sounds like it'll be a slow go.

When i read the above I´m wondering why my little palm (four fronds) totally defoliated with the last freeze (around -3°C)?

Carambeí, 2nd tableland of the State Paraná , south Brazil.

Alt:1030m. Native palms: Queen, B. eriospatha, B. microspadix, Allagoptera leucocalyx , A.campestris, Geonoma schottiana, Trithrinax acanthocoma. Subtr. climate, some frosty nights. No dry season. August: driest month. Rain:1700mm

 

I am seeking for cold hardy palms!

Happy to report that four xerophila still moving along here. All through two full winters.

This fall has been very mild. No frost.

I've lost two seedlings in unprotected locations.

A prime spot appears to be nestled up against west side of a row of very tall Italian Cypress.

I think this is the hardiest of the genus.

Seems tougher than rivularis and glauca.

i have one in my yard for 7 years. has experienced snow and low temps regularly below freezing (low 20s) and it does fine. the leaves do get damaged but it comes back every spring. planted from a 3 gal and now longest leaf is over 5.5 ft tall. this thing loves water too from my experience. it is planted in open area too but now some palms are growing in and stealing its sunlight.

cheers
