For some reason I have aquired at least 5 of these from good 1 gal size to hefty 5's.  Some sheet covered, some not. 4 nights under 30F, 2 of those at 26F can't see any damage.

Small ones seem more susceptable to root rot than cold...

Very small plant, about 8" tall overall, but about 6 years old.  No protection and no damage to 5 hours of frostless 27F... Dypsis baronii 3x this size just 2' away completely killed.

2 weeks later and now some minor leaf damage on one leaf

Two babies overpotted in five gallon pots, three or four baby leaves, two nights, 24.8 F, no protection, some spotting and yellowing; two more days under an overhang, not any worse.

5 gal size, planted last summer, some protection from other plants.  Not sure, but estimate around 25 F on Dec. 19th.  Had protection for the Jan freeze.  No damage.  Looks like this one won't take frost on the fronds.

Wow you have quite some size on that one. Try you hardest to keep it alive. Something that large has some value.

Steve, any update on this one?

22f puts it in the Juania australis catergory for me and would be worth trying it out in the ground.

It's got a green newest leaf so I'm gonna guess yes. Now let's see.

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

Covered by a small 4 tier mini green house. Substantial damage/ 75% but still alive.

I was told the one in Fallbrook survived, recovered, and now may be near blooming. Does anyone have an update? (or a picture)?

I am growing this one in North Florida but I dont have any illusions about survival ----- its a solid zone 10 plant I believe. You have to remember that it grows so slowly in these climates that if it gets a atlot of frost damage --- it may take a few years to recover ----- so you have this problem of back to bac freezes in sucessive years --- you never get good growth. I try to cover mine each year to minimize this. About 2 years ago I hurt my back and had a hernia and couldnt work on a ladder to cover--- I chain sawed the foliage down to abotu 8-10 feet so I could throw something on it. --- it has takedn to this time to really get back to what it was. You really have to plan to keep this plsny going ---

best regards,

Ed

One 3-gallon sized plant in the ground under canopy protected by a plastic bucket and leaves exhibited defoliation of all but the spear. Ultimate low was 16F with several lows in the upper 20's and low 30's. The spear has since opened.

Any update on some of the ones subjected to low 20's (or lower in this thread). I have some that are itching to go in the ground, but don't really want to sacrifice them.

I'll be planting one here within a month.

It had no problem being in a pot under a southern eave with recent official low of 20F.

It's going to replace a Kentia that has barely survived for four years and just got beaten badly..

It'll be on the western side of tall Italian Cypress.

Wish me luck.

This is a beautiful jubaeopsis caffra growing in East Los Gatos/South San Jose that didn't even blink an eye from a solid week of nights 27F to 29F temperatures for 10+ hours below freezing. This is simply a spectacular hardy palm! See http://www.wunderground.com/weatherstation/WXDailyHistory.asp?ID=KCALOSGA13&day=9&year=2013&month=12 for details on the freeze, Dec 4th through 12th. This WX station is literally 3 blocks from where this palm grows. Palm has some light overhead canopy to the East, clear skies to the West.

Two seedlings about 12 inches tall with divided leaves, unphased by the cold from this same freeze, 26.6F on the worst night. Mine were fully exposed to the night sky, no overhead canopy.

3 consecutive nights 31 F, 23 F, 25 F. 2 foot tall, 5-6 divided leaves. Covered with my thermal jackets made from laminate floor underlayment. 3 hot hands underneath on the night at 23 F. The palm is almost unphased!

Brutal winter.... 3 nights 30 F, 29 F, 25 F. Protected from sleet and snow with thermal foam... no glove warmers this time. Estimate 30-40% burn on outer leaflets. Definitely still alive.

Update on mine.

Fizzled out in late Spring 2013.

I haven't ruled this one out to try again.

The one above was a one gallon and got beat up by construction crew in addition to Winter cold.

If I try again it'll be with a bigger specimen.

Frost and low of 32 for about two hours - you can see light burns on the newer fronds. The dried tips were pre-existing.

Toasted after the first night.  Under partial canopy.  No other protection.  A second one under nearly full canopy looks much better but has burn spots wherever clear sky was visible.  No frost.  Will not be planting my remaining plants.

Here are my lows for the Feb. 2018 freeze:

2/21  21.6F

2/22 23.5F

2/23 27.9F

2/24  25.1F

2/25  26.5F

2/26  29.3F

And duration info from a local AG station.
