   Hyophorbe verschaffeltii

   Three plants total: one seedling in a pot under cover, one 2-ft, first winter in ground, one 5-ft, second winter in ground. Lowest low 31, dry. Those in ground noticeably more yellow than before the severe cold, although they were already somewhat yellow. These are planted in a south-facing area close to a garage wall which radiates heat after sundown. Seedling looks fine.

   24F low, no frost, 15 gal sized planted away from house and wrapped in blanket with box over top, virtually no damage. 3 nights below 28F. No true overhead protection, planted in shade of fence. Edit: Minor discoloration showing now to part of outer fronds, still bright green interior fronds. Looks like a box covering at 24F was enough. (no heat source was given). Maybe 15% damage.

   Zone 7a, LI, NY. Endured 25-30 degree temps with no damage at all. Then seen about 14 degree temps with strong winds for about 2-3 days (felt like it was zero with wind chill). Entire plant turned light green and thinned out. No burn signs. Covered it with plastic and added x-mas lights afterwards. Very cold temps followed 15-20 degrees for a month? Uncovered about 4 weeks ago and dark green color is coming back and looking real healthy. Also have a potted Fortunei which I left in the garage during all this cold. Tips began to turn brown. Pot seems like it was frozen. I moved it indoors. Center spear began to turn yellow/white. After about 2 weeks indoors, be…

   Six-foot jubaeas: Two nights fourteen degrees, 14 hours below freezing, numerous nights below 20, fifteen nights below 25...drumroll...NO DAMAGE. OK, tiniest bronzing of distal leaflets, ONLY on oldest 2-3 fronds. Ten other jubaeas, from straps in planter to 8 feet, no protection, very light- to no apparent damage, almost two weeks since coldest weather.

   Allagoptera leucocalyx

   Small pinnate specimen (1gal size), planted mid-2009, exposed position. Looked fine through a few light/moderate frosts & freezes as low as 28.6F. Began to show moderate-to-major foliar damage with two back-to-back freezes to 25.9F. The big freeze of 2010 (64 hours continuously below freezing, lows of 23, 18.4, 19.7, 19.8) has completely toasted exposed foliage. I have it mulched to the spear and expect it to recover from below this point. This one is not as leaf-hardy as I had hoped, it seems no hardier from that perspective than A. arenaria.

   This one faced three back to back nights with -1,8ºC, -2,6ºC and -3,8ºC, this one with not light frost. This in December. These recent days, one isolated and frosty night at -3,6ºC. In the middle one night at -0,5ºC. Then, some strong frost in two nights. Light frost in another two nights. However, this palm is located in the south side of the yard, in a place almost non atacked by frost. And is a big sized palm. As you see, not yet totaly burned. I am expecting the recovering, after February

    Two small (8" tall) specimens under canopy. 2007/2008 winter, about 10 freezes, the lowest was 23.3F (15 hrs below freezing). 10%-15% leaf damage on both specimens. 2008/2009 winter, low so far after 8 freezes has been 24.1F (14.5 hrs below freezing). One specimen 20% damaged, other specimen no damage. This is a surprisingly tender Phoenix. None of my other Phoenix, whether exposed or under canopy, have shown one iota of damage (sylvestris, sylvestris robusta, acaulis, theophrastii, reclinata). Plants were purchased from J.D. Andersen as "Phoenix humilis" and provenance is unknown. Perhaps there are stronger forms from other provenances. This is also a very slow-growi…

    24 degrees... two specimens in different areas of the yard. Both from 5 gallon pots 3/05. The more exposed one - severe browning on all leaves. The other - some spotting, some brown tips. Definitely seems more tender than cunninghamia Edit 1/30/07.. both appear dead. Way more tender than cunninghamia.

    Now that it's July I wanted to report in on losses and survivors in the January 2018 freeze. I had 5-6 consecutive nights below 20F, with absolute lows of 14F and 13F. Highs in the low-mid 30's. All plants fully exposed, no canopy unless noted. Ground froze to at least 2-3" in many areas of the yard. Most of the results are somewhat expected, I did not protect anything as the severity of the freeze caught me off guard (it was forecast for low-mid 20's here). Palms in the ground: Butia odorata (mature) Silver form, 50% defoliated. (5-7 gal) - Smaller silver Butia 50-100% defoliated but survived without aid. Many seedlings were killed. Butia sp. (5 ga…

    Since no one has posted temps for this palm, I thought I'd show my brother's palms growing in Kansas City, MO (Zone 6a). Temps: His low this winter was -3F but he had 13 days in single digits which is when all the damage happens. Protection: Palms were buried in mulch. On coldest events heavy plastic was thrown over them. No lights or external heating.

    Our January 22 freeze didn't affect a small Dypsis carlsmithii (about four feet tall, with no trunk yet). It's at the edge of shade from a laurel oak and in a bed with other palms and cycads about the same height. Palms in the yard, with full exposure to the sky, that suffered no damage include Archontophoenix cunninghamiana, A. tuckeri, Carpentaria, Coccothrinax barbadensis, Dypsis decaryi, Thrinax radiata, and Dypsis "fine leaf". One of two Satakentia liukiuensis (about 6 feet tall) suffered a great deal of leaf browning. Neighbors' Dypsis lutescens suffered considerable leaf browning. The temperature, under a clear sky with a slight breeze, fell to freezing abo…

    At the risk of sounding like Bossy Bob...there's a lot of Chatty Cathys on this thread. Let's keep it about the freeze data...whoever volunteers to edit this work someday will have to sift thru less BS if we keep it to the point. Clever, witty quips are unavoidable(since this is a comedy club as well), as well as comments and observations pertinent to the subject. Also, some are assuming we know how cold it was, what size the plant, etc so please be complete...I'm assuming that incomplete data will be edited out, so you're wasting your time sharing incomplete data. We have one chance to get this right, so lets not bugger it up Don't forget, there is a weather threa…

    Here in Maitland (northern suberb of Orlando) we had 8 nights below 32 F during the recent extended freeze event. Of these, 6 nights were in the 20s (28,28,27,26,25,29). Here are some photos of the damage my palms have received, taken today (sorry about the less than optimal lighting). Roystonea borinqueana, almost 100% defoliated. I expect it to come back just fine.

    In north Florida. Low of 21 F, 10 hours at freezing temps. 3 days of freezing temps. No overhead protection. Little or no frost. 15 mph winds, advective freeze. No "new" damage. This plant had a bad case of what I think was leaf skeletonizer. I believe I took care of that problem and there doesn't appear to be any new damage from the freeze. This plant is about 5ft OA, with about 1.5 ft of trunk.
