Hyophorbe verschaffeltii

Recommended Posts

Kim

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.

28F, no frost. Unhappy to be sure, but never looks well in winter either. 4 ft. plant. Looks to survive, if it gets a break.

No frost.

Seems to be ok right now. Still yellowy. In the warmest part of the yard which didn't get below 34F either morning. The rest of the yard was 29F Sun AM and this morning. No frost.

These survived 29 degrees in my filed last year with a hard frost...bottles and spindles!  They are coming back still but really don't look half bad.  This was a one night event.

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.

Variable damage from minimal to severe.

Two years and one month update: the seedling in the pot didn't survive, but the two palms in the ground continue to grow through winter. This year the low temps never went below 36.1F, and many nights well above 40F. The winter was quite mild, with several stretches of warm, summer-like days well into the high 70s. Everything in the garden is yellowish, but very little damage otherwise, even on tender ti plants. By this time (mid-Feb), lower temps are out of the question, the difficulty will be not high enough highs for the next two months.

This one took 3 weeks of sub zero temps with at least 2 excursions to -4c/24.8v and 2 lower dips to -5c/23f.

It is planted as an experiment understory to my Washingtonia robusta which has severely fried.

It looked OK for a while although the remaining new frond which did not get sunburnt last summer has gone a darker green. Also a storm has now since snapped the remaining good frond in half! Only time will tell if it recovers......

Both my large (10-12 ft) spindles got through out epic 2-week cold spell with only minor damage. The cold included a number of days where highs didn't reach 50F and nights fell to near freezing. On Jan. 9 we received nearly 1" of rain and temps didn't rise above mid-30s. That night saw a low of 33F. But on Monday morning, Jan. 11, the thermometer in our backyard lemon tree recorded 28.5F. I tend to believe that reading, as 1 week later our lemon trees dropped damaged (mushy) fruit. That has never happened before.

Through all that our 2 spindles suffered frond burning and bronzed crownshafts. Given a more normal remainder of winter, they should pull through with few problems.

Here's a spindle at Vero Beach's community center, a month after December's cold with (at the airport, at least a mile from this spot, which might be slightly warmer), 26 F (-3 C), then 28 two weeks later. There was no frost during the month, and none since then.

This palm's on a dry site with no irrigation, so is much smaller than one in partial shade and irrigation at Heathcote Botanical Gardens in Ft. Pierce.

Here in NW Orlando we had a night in mid-December 2018 that was an estimated windy 35F, one frond burned on each of 2 spindles in my backyard with no cover.  January 21st we had 4 hours at 33-34F and they are showing a lot more burn.  These were planted in April 2018 nearly dead (basically free to me to rescue) and were still pretty significantly potassium deficient in December.  The leaflets were probably 85% green in December.  Nearby potted bottles and foxtails were basically untouched, with only a small amount of leaflet tip damage.  

So the moral of the story: Make sure your palms are healthy and well-fertilized before winter! :D

Constant cool frostless weather (50s to 60s year round) seems to be much worse to a palm than occasional freezes and then recovering in hot weather.
