cold damage report for palm collection at Leu Gardens

[Eric in Orlando]

Here is a report of the cold damage incurred to the palms in the collection at Leu Gardens. Leu Gardens is located in Orlando,FL. Our location falls into USDA zone 9b and is borderlines 10a. We are located on the southeast shore of Lake Rowena which provides for a protected microclimate.

The winter of 2009-2010 was a record setting for the duration of cool and cold weather. December was very warm but it turned cold in early January. The absolute low was only 29F but the duration of cold in January set records. February and March was also much cooler than normal. Many plants did not show much injury for several weeks and slowly started to decline thereafter.

Here are the stats for the cold spell in January. On the night (Jan. 10) it dropped to 29F it was below freezing for an amazing 12 hours. Also the nights of Jan. 10 and 11 had very heavy frost in the open areas. February had no below freezing nights but there were quite a few nights in the mid 30sF to the low 40sF and highs only in the 50sF.

[tropicbreeze]

Looks like Calyptrocalyx didn't stand a chance.

[Eric in Orlando]

Not even C. polyphyllus which is supposed to be one of the hardier ones. I think it was just the long relentless cool/cold that killed them.

[redant]

Excellent info, I'm going to keep this info for any future shopping, I'm done with zone pushing and would prefer a less diverse but more stable garden.

[gsn]

Eric,

Thanks for the cold damage report..

Leu Gardens has to be one of the best microclimates in central Florida ,at least inland. As some of the close surburban areas of Orlando got down to around 25F,26F according to reports, and from what I researched on weatherunderground.

To have only gotten down to a low of 29F is amazing,I got lower than that last year (2008-2009) over here in Titusville 28F, this years (2010) low was 24.4F!

I only have a few palms that weren't damaged,some were killed out right and most severly damaged. I won't list them all only to say the usual old standbys (queens,butias,mules,phoenix,chamerops,sabals,serenoas) are the only ones that came through unscathed. Any crown shafted palm I had was either killed ,completely defoliated,or at least 75 percent damaged!

Two back to back freezes here have driven the point home for me,that at least here in my climate in east central Florida that zone pushing is like beating your head against a brick wall, my head loses...

I'm with redant I will keep planting palms,but I will be planting withan eye toward more cold hardy palms.No there won't be as many diverse species in my garden,but at least hopefully they will all be green and growing come April ,rather than brown, I like green better even if common!

I'll leave it to the botanical gardens like Leu to test the limits,and come see them at the fantastic tropical oasis ya'll have created there!

[paulgila]

eric did you type ALL that? mustve taken a loooooong time...

[sarasota alex]

Eric, thanks for the info! I have a couple of questions. I remember seeing pictures of Jubaea chilensis at Leu. Is it still there? I didn't find it on the list. Also, was Tahina protected in any way, or it just naturally was able to handle the sub-freezing temps at such a young age?

[PalmatierMeg]

Thanks for the detailed info, Eric. Leu's temperatures mirror mine closely. The palms I have/had in common with it show similar outcomes. My ultimate low was 28.5 the morning of Jan. 11. I can see that none of my Calyptrocalyx should be planted - unless I'm prepared to take drastic means to protect them.

[Trópico]

Thanks Eric! I would suppose most were under oak canopy. This deserves to be in the cold damage section.

[BeerPlant]

Frantasic and invaluable info Eric! Especially for us on the edge of central fl who are in cold pockets. If palms recieve severe damage at Leu then we might as well not waste our time unless under extreme protection!

Thanks Again!

[tikitiki]

I have some of the same results and some different. My Kerriodoxa elegans look perfect no problem at all. While some of yours that have no notes were killed out right in my yard.

[edric]

Ditto! Thanks for the up-date, Ed

[Tyrone]

Amazed at the Tahina.

[peachy]

Thanks Eric, altho on the other side of the planet, these stats are very handy for me as I live in a similar climatic zone. Strange how some palms that survive a minus 5c frost unscathed here, died in the Leu gardens and palms that died here survived there. Still I intend to copy and keep your list of unscathed palms for my shopping list.

Peachy

[Alberto]

Thanks Eric!

I saw the B.eriospatha x B.microspadix were untouched...Not a surprise! What is the size of the little hybrid now?

What surprised me was the same kind of burning (little damage) to Dypsis plumosa and D.ambositrae. i was expecting to the real ambositrae to be hardier then the ´´fake or fine leaf´´ or more properly B..plumosa!!

[Eric in Orlando]

eric did you type ALL that? mustve taken a loooooong time...

I already have the master list saved as a Word document. Just printed the list, went out and made notes, and typed in the damage results.

[Eric in Orlando]

No, that old Jubaea died back in 2002, it got a bud rot and died during the summer. It had about 6ft of clear trunk.

The Tahina was not protected at all and is growing in a fairly open location so probably had some frost on it too. Its only about a foot tall.

[Eric in Orlando]

Thanks for the detailed info, Eric. Leu's temperatures mirror mine closely. The palms I have/had in common with it show similar outcomes. My ultimate low was 28.5 the morning of Jan. 11. I can see that none of my Calyptrocalyx should be planted - unless I'm prepared to take drastic means to protect them.

I think most of the Calyptrocalyx would have been fine if it had been a "normal" freeze (if there is such a thing). One or 2 nights in the upper 20sF but then warmed back up. I believe it was just the sheer duration that wiped them out, especially C. polyphyllus. I had one years ago in a container that I left out and it was 29-30F a couple nights and it wasn't bothered. I have a few extras that I will be planting back out in the next month. They were all growing in a very protected location under tree canopy.

The hybrid is about 2ft tall now.

Those 2 Dypsis are planted very near each other. Size might have something to do with it. The D. ambositrae is small, about 1-2ft tall while the D. plumosa is 7ft.

[Eric in Orlando]

Glad everyone found the info useful !!!

[sarasota alex]

Eric, I noticed Myrialepis paradoxa on the list of palms you had donated to the CFPACS auction this weekend. Could you advise on your experience with this palm's cold-hardiness for Central Florida? It's not on your list above. Thanks!

[Eric in Orlando]

I'm not sure, I just planted one this summer so it is going through it's first winter. It comes from strictly tropical habitat but some other rattans like that have been semi hardy. This one looks to be a giant !

[Central Floridave]

Sorry to jump on this thread, but more info on CFPACS meeting this Saturday:

http://www.palmtalk.org/forum/index.php?showtopic=30335

Thanks Eric for the freeze info. Its invaluable. I'm pointed to this thread often on my numerous google searches on various palms!
