Mine seem for the most part ok as well. 24 with no frost. Some spotting on older leaves.

I have two small ones in the ground that I planted out of 2 gal pots last summer.

One is 5 feet from my swimming pool under a large palm, looks pretty good, some leaf burn.

The other is fully exposed out in my arctic front yard and it looks like someone beat it with a tennis racket.  As bad as it looks, l think the spear is hanging by a thread.  

24.9 F in protected area of back yard.

R. rivularis takes a while to show damage if it wasn't burned initially.  First signs of serious distress are buckling rachis.  My 15g stagnated for about 6 months before the spear pulled and then quickly died after one night of 23.6F, fully exposed with frost  last February.  Looked fine for a couple weeks.

Hopefully larger trees or those in the ground will fare better.

The two I had (past tense) planted deteriorated quickly after the frosts and during the recent rains.  The plant in my very cold front yard originally looked like the spear had at least a chance.  The one in my back yard originally appeared to have only minimal leaf damage.  The leaves and spear deteriorated quickly.

These plants are too small to take the wait and see method.  I'll try again with larger ones.

It took several weeks to show but most of my majesty palms show 25 to 75% leaf burn. Minimum was 26F. Although these palms produce lots of new leaves yearly, they're still slow in my book. My oldest has been in the ground for several years and still no woody trunk despite tons of water and fertilizer.

We planted this Majesty Palm 3 years ago. It is about 12 foot tall with about 1 foot of clear trunk. It's planted pretty close to the house but gets North winds. We always wrap the trunk with Christmas lights and try to cover it with frost cloth when we know below freezing weather or frost is coming. We had 2 days with light frost and a brief drop in temps to 27 that caught us off guard so the palm was not covered. Some of the fronds got burned badly but this thing grows so quickly you can hardly tell it suffered any damage. The picture below was taken August of 2008.

It was about 4 foot tall and had a trunk about the size of a beer can. The place we have it planted is right at an area that drains our whole yard when it rains. So it gets quite a bit of water and we also water it daily.

I think these palms are very sensitive to frost. What I do with mine, when I can beat the frost, is tie all the fronds up with a couple of long bungee cords. Then I wrap it from top to bottom with Christmas lights. Afterwards I wrap the fronds with two layers of frost cloth and tie it at the bottom. I also have a 90w flood light going at the bottom of the palm on cold nights. This works well. The only problem I have had is getting caught with a heavy frost on nights that it doesn't get below 32 degrees. The coldest mine has seen is 26.

This year I also sprayed the fronds with Anti-Stress 2000. We'll see how it works. So far it has made it through two light frosts this year on nights where the temps were about 36 with zero damage. No protection other than the spray and the 90w flood. I feel i have been pushing my luck so I will probably wrap it up this weekend for the winter.

Thanks for the info. Do you leave it wrapped up all winter once the cold sets in (we are getting to that point here)? I have some foam pipe insulation that I was going to wrap around the base of mine today.

I haven't, but I have also gotten caught off guard with a frost I didn't expect. This year because of the size and difficulty of wrapping now, I think I am going to leave it wrapped until about March 1st. I wll probably wrap it in two weeks.

I have the foam pipe insulation too. It works great. I also bough a roll of foan insulation at Lowes. It works great on wrapping palms with more trunk. You can wrap it over the Christmas lights and it really hold in the warmth.

We hit 29F here two nights ago and my 4 majesty palms have zero damage. I did not wrap them this time although I usually do if it is forecasted to be in the 20's (which is rare). Two are out in the open and two are under a light canopy. We've hit 30F a couple of times this winter along with a few more 31-32F nights. They seem to take a light freeze with no damage at all. The fronds, however, will incur damage with a frost. I do have some brown spots on the fronds due to frost, but it's not too bad.

We even had that snowfall back on December 10th - it was snowing at my house for several hours, and the palms came through with no damage:

img3635qq7.jpg

Overall, they seem to be pretty hardy. I have read that they are hardy to 26-28F and from what I have seen, established ones may be even more hardy than that. We hit 26F a couple of years ago and I didn't see a single fried Majesty Palm in the area. I wrapped my crowns and upper trunks for that event and all I noticed was some browning of the tips.

Oveerall, I am very pleased with these palms as they give my yard a truly tropical look yet I live in zone 9.

Later on, I will add some more pictures with a post-winter update.

During the severe cold snap in Florida (January 21 thru 23, 2009) this majesty palm saw around mid 20s on the morning of 1/22/09.

This palm will recover nicely as it also looked like this from the radiational freeze of 1/5/01, when it was actually a degree or so colder.

Thanks, Jasons & Walt, for your observations and photos. I have read that the rivularis has surprising cold-tolerance for a such a tropical-appearing palm, but seeing how it survives snow always surprises me.

Walt - I am so sorry to see the damage your riv took. I remember seeing a photo of it in warmer days, what a striking palm it is.

Back in '01 ('03?) - the only serious freeze I recall here since '89 - our rivularis was out in the open - unprotected at a temperature of 27F of at least 2 hours duration. While my heavily-protected spindle had almost 50% damage, the rivularis experienced only some browning of the leaflets. Mind, this palm had already been moved twice, and was in some poor "soil" at the time of the freeze, so it wasn't in optimum condition to receive this kind of chill.

(Footnote: thanks to the city for hanging yet another powerline, this time directly over the rivularis, I once again moved the poor palm - to the backyard where it now has better soil and filtered sunlight.)

Jasons - your photo reminded me of another photo - posted years ago by "Mike in Houston" (I think) of a rivularis in snow. Very moving photos, both yours and his. Wish I could find Mike's, but it was on the previous IPS board.

No, no. That isn't my majesty palm, but a distant neighbor's. My largest majesty palm was hurt, but not quite to the extent as the one in the photo I posted. My other majesty palms were also hurt, but much less so. In fact, it took an entire week before the damage finally started to show. Some cold damage just takes so long to manifest itself.

And yes, it was January 5, 2001 when we had a bad radiational freeze. That was my coldest freeze ever in the 12 winters I've lived here. Last Thursday was the second coldest for me.

Walt, my two majesties are totally defoliated like the one in the pix above. I don't even know if they'll live (but I'm not that attached anyway, and they were free). I wasn't here, but I think it dropped to around 25-27 and stayed below freezing a looooooong time (maybe 14 hours...maybe more). I think we had a real heavy frost too. Now we're holding our breath again to see if we're going to have yet another night that cold (odds seem to favor it). Too many freeze tests this winter!
