I have seven of these, six in the ground, and we had 26.5F as a minimum during this cold snap. No visible damage on any of them.

Sweet. Good to know. Did you have frost up there?

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

edited 1/30/07... all plants showing more damage, probably 50-60% browning... doesn't appear life-threatening.

Nice job. Mine are so slow compared to what they claim. Mine just started showing trunk 2 years ago and are growing at a snails pace.

Ravenea rivularis, 15 feet overall, 18" dia. trunk, 18" clear trunk

24.1F, no frost, no canopy

Minor tip burn on recently opened new leaf

I fertilize the crap out of this palm so maybe the high salt levels helped.

27F for 5 hours, no protection, all leaves fairly 'bronzed', but spikes seem OK.  Seedling about 6 years old no trunk yet.

A full week later, and all leaves lost.  Spikes (4 of them) seem mostly undamaged... but then I thought leaves were hardly damaged at first...

This shows my neighbor's trees- these about 12' tall overall.  Two others, a street over, only 5' tall, are both dead as can be (planted along street with no protection at all).

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.

I thought mine would be fine, but alas, 10 days later they look like the ones in Geoffs pic....more detailed info later  :(

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.

Palmy

Folks in the bay area:

How do yours get so big? I cant even get mine to last more than a few weeks, even in the summer. I have one that I just forgot about and it is doing badly but will survive till spring.

Two - three nights ~ 28-30, under frost cloth.  Major damage.  These palms are higher maintenance than my wife!  (You know, just between us!)

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.

Went below 32F at 330am, went back above 32F by 830am. 5 total hours of freezing temperatures. Ultimate low of 29.7F with 7.6 "freezing degree hours" calculated as discussed in the weather forum. Moderate winds varying from NNW to NNE all night, dewpoints in low teens, no frost. No overhead canopy in my yard. No protection provided. Photos from 4 days after the freeze event.

Minimal to no damage:

South side of yard. The one on the north side looks the same.

I have one that is about 15 foot and 3 foot of trunk.  

29F for 2 hours

Below 32 for 5 hours

The trunk was wrapped in Christmas lights and covered with insulation.  The fronds tied up and wrapped in frost cloth.  

No frost.

The fronds touching the cloth had some noticeable damage.  The inner fronds had no damage.

The two big majesties in front of the Vero Beach Museum of Art were not damaged by the January 2010 cold spell. The site is protected, a bit, by the Indian River. Coconut palms in the vicinity (i.e. Riverside Cafe) were less badly browned than near the airport, where the lowest temperature of the nearly two weeks of cold was 28 F (-2C).

After the record prolonged cold of the 2010 winter, Ravenea rivularis (Majesty Palm) will return. The leafs burn at 26 F with heavy frost. Leaf sensitive but bud tough. The Majesty Palms in town and at my house are returning yet again. I recorded 19 F and provided no protection other than a little extra mulch around the base. I have NEVER had a spear pull on a Majesty Palm. I believe me…I pulled hard after this winter. Others in town (Tallahassee, FL) were not even mulched and made it as well. Keep in mind these same palms in pots or out in an open yard most likely would not have made it. In the ground and by your house, these guys are tough. As with a lot of tropical plants, the more sun the better for a fast recovery.

I wholeheartedly agree with Floridagrower about the nature of this palm.

I've been growing these in large pots basically unprotected over 4 winters now here in the Sacramento Valley.

Additionally a few are established in the ground in my neighborhood.

We usually have a few frosts into the high 20s. Last December we had a low of 22 degrees.

As noted above it takes two or three months to see the full extent of the freeze damage.

Typically by February or March here they look awful with nearly complete defoliation.

Amazingly by summer with copious water and fertilizer they look ok or even good (I also apply epsom salts).

If you want year-round beauty in a frosty climate this isn't a good choice, but I just consider

it a deciduous palm and enjoy it in the heat of summer and fall and focus on other palms and flower bulbs

in the spring. They are fairy inexpensive here and the small ones can be treated as annuals.

I have two majesty palms outside in the ground. So far they have survived the winter and one night was 16 degrees F. I have them wrapped with burlap and Christmas lights. There are no signs of cold damage, but i did have to cut the fronds off because i protected them too much. One night i placed black plastic over the palms and the lights got too hot inside. So the tips and middle of the fronds "cooked". Everything else looks good though. I just have to wait to see what happens when winter is over, and when the danger of frost has passed.
