The big  (25 ft?) Roystonea regias along Morena Blvd. heading north to Costco -- fried.  That must be a cold canyon.  Every one is frizzle-tipped, but the crownshafts are still green, and I couldn't tell for certain, but the unopened spears may still be green.

My 2-ft. baby, 2nd winter in the ground, 3 ft. from an ice-filled bromeliad:  no visible change.  So far.  (32.2 and 31 lows last 2 nights.)

My 3-ft. baby in a tiny pot, sheltered between 2 buildings on a concrete patio, no visible change.

I'm surprised that you got so cold Kim. Pt. Loma is usually the warmest part of the county, isn't it?

Low of 29 Sat AM  no frost

I have 3 with about 4 feet of fat trunk.

1 protected with heat. No damage.

1 with trunk in amongst foliage with crown exposed. Freeze damage to a couple of fronds.

1 totally exposed. Haven't checked it yet.

Hmm.

My Little Rascals.  Spanky and Butch (Second biggest and biggest!) got KFC'd.  

Alfalfa's okay.  Miraculous.

Go to court in the morning, come home . . .

2 R regias that saw at least 29 and probably 70 to 80 % leaf burn.  Palms should make it thru but looks like crap for now

This may not be helpful as I don't have the temp data, but at South Coast Plaza in Costa Mesa Sunday afternoon during the Charger/Patriots game, the very tall royals lining the street looked absolutely pristine in a very flat, open area.  You would never guess it had been cold (maybe it hadn't).  Anyone been by there Monday or later?  Are they still looking good?

somewhere between 25 and 27.5 and no frost, 5 @ 12'+ starting to trunk, all in the open, >50% damage

Update:

One R. regia, against south wall in lower part of yard, exposed to c. 24.8 for four solid nights, severe damage, but spear still green.  (I believe cold air drained onto it from the roof of the house),

Another specimen by the patio, away from house, much less damage, probably slightly higher temperatures, at top of slight slope.

Another specimen 60% leaf burn after four days of 28-29 F.

12 small specimens in pots, under shade cloth, nearby exposed areas to 24.8 for four solid nights, no damage.

This one near 100% defoliation.Unfortunately,newest spear was just opening and is totally dried out.It is a larger tree with over 6 ft of wood so all we can do is hope it pulls through.I have seen similar sized ones die here at slightly higher temps!

Royal seedlings. Even though side by side,some totally fried while others seemed untouched.These were all unprotected.Genetic variation?

This is a good idea!

okay, I have a Royal, it could be a Florida variety because they guy I got it from dug it up from somewhere around Naples, but I am not sure.  It is begining to form a trunk.  It is in North Brevard county, Fl and it took two hours of 26 F with very little or no tip burn, which is amazing.  Of course it was also planted in a canopy of sabals.  It also took 31F with no damage, and then in the Feb 2006 freeze (location tempreture unknown), took some tip burn on the ends of the fronds.

Its interesting how close they look like Queens when still young.

I cant get a Royal at the moment as my usual suppliers dont import any (No names!), but I had no problems in getting a good sized Queen last September which was imported for me from Valencia, Spain.

Just started the high nitrate feed (with humates) 2nd dose today but I have avoided Broad Spectrum Myco as there are several other palms around looking quite happy so Queen is probably happy too  as the soil seems palm receptive.

Given the chance I would probably try a Royal under semi-canopy or at least close to my house.

Posted this in another thread, but thought it would be good here as well.

Like all others in my yard, experienced 25-26F as a low, and extended time below freezing over 5 nights consecutive. 100% leaf burn after first night, but spike looked totally fine. Never missed a beat afterward... all nice leaves.

Photo left - Jan 07, Photo right - Sep 07.

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 damage so far:

These 3 Cuban Royals have been in the ground for 10 years growing at a Best Western a few miles from my home. They have been through frost, snow, and even an ice storm with ZERO protection. The are completely unsheltered and even exposed to north winds. The coldest emperatures I know that have seen is 26 degrees. The suffered slight defoliation then but as you can see, have recovered quite nicely. I was so amazed I had to contact the owner about the palms to find out when they were planted.

Big Tex,

I have seen those before but cannot remember where they are located. Could you tell me?

They are off Hwy 6 close to 290. The Best Western is backed up to the Hempstead Hwy and Hwy 6.

These royal palms are in Labelle, Florida (Hendry County), about 25-30 miles inland, N.E. of Ft. Myers, Florida. They were freeze burned from a severe radiational freeze on January 5, 2001. This freeze even burned royals and coconut palms five miles inland from Naples, Florida.

The queen sago palm to the left is under dense live oak canopy and wasn't burned, due to the tree canopy holding down rising ground heat. However, queen sago palms in the open were severely burned.

Low of 27.3, radiational freeze, no wind, unprotected. below freezing from approximately 12:30 AM to 8:15 AM. Lots of frost. Pictures 36 hours after the freeze.

Fair condition...25% browning now - maybe more later - minimally trunking specimen.

02a85915.jpg

Young one in there took more damage...I'm going to call it 50% browning...kinda hard to see in this pic but there is a more brown foxtail frond hanging over it.

I have 7 seedlings with strap leaves in pots, about 6 inches tall. Collected in habitat in the Fakahatchee strand. Low of 28˚ F with no frost. 6 seedlings were unscathed, 1 had 70% damage.

This was Butch, also pictured below.

Hard to believe, the tenacity of life sometimes. Butch is now about 35 feet tall, and about tree feet across the base, maybe a mere 2 and a half . . .
