Dypsis 'ambositrae'

[Geoff]

Not sure if these are the 'real' thing, but what's been sold as D ambositrae in California for the last 10 years.  Anyway, both slow growing 6 year old seedlings (4' over all about) showed no damage I thought... but just checked on them and 27F for 5 hours appears to have done more hurt than I thought.  Leaf color looks pretty good.. but these 'normally' have darker leaves.. however, all petioles just 'melted' and only frizzled spikes remain... suspect both plants are dead and just don't know it yet.

One "fakey" fine leaf about 4' tall stem... no damage at 24/no frost.

4-5 seedlings at the base, covered with a sheet, to early to tell if they're fakey or real Ambo, some leaf loss (50%).

[DoomsDave]

About a dozen fakey Ambositraes in the ground, most about 1.5" (4 cm) across the base, about 4-5 feet (1.33-1.66 m) tall, no discernable damage after four days of 28FF (-1 C)/

Two five gallon potted "dark form" 50% leaf burn after one day in 24.8 (moved to garage)

Very little damage to mine here in Modestooo planted close to my house... under the overhang. Official Modesto low temps 23f... my  yard thermometer 26f.

Update:

A flock of about 8 fakeys, all about 4 four feet tall, exposed fronds showed some damage after four nights of 28-29 F, -1 C.  Solid nights.

But, they're coming back.

10 plants, planted as group, 6' OA height. Some canopy, near pool and house.

22f, multiple hours and nights below freezing

10% leaf burn

All plants fully recovered

[STEVE IN SO CAL]

Four plants, 3' OA height

19f, many hours and nights below freezing

Killed outright

Apx. 10 fine leaf versions in various part of my yard. 27F and many nights at or below freezing with some light frost completely exposed to partial canopy on some. 50% leaf burn on all. Spears look fine. Some in the ground 4 months some 1 year. No difference.

6ft OA in the ground for 5 years no protection. Took a frost last night. 2nd night at freezing. no problems yet. lt Held the seeds so far.

About a six-foot fine-leaf, in close company with an Archontophoenix and some other palms, but pretty much exposed to the night sky, seems undamaged after 32-31 degrees from 9:30 pm until near dawn, when the temperature briefly hit 30. Dry air, no frost.

[Dave-Vero]

After my last post, we had more nights of slightly-below freezing temperatures and one that hit 28 degrees at 10:30, then freezing or just below until dawn, when it dived back down to 28. Rose above freezing an hour or two after dawn.

Still no damage. By way of comparison, Archontophoenix cunninghamiana, Carpentaria, and several assorted Coccothrinax suffered no damage, while Archontophoenix tuckeri and Dypsis decaryi suffered limited browning. Satakentia liukiuensis was badly browned.

Dypsis plumosa looks reasonably hardy for our climate.

In reading all these posts, it seems everyone is rating the Palm that is now officialy Dypsis plumosa. I wonder if there is a way we can get the Post Title changed to reflect that? Perry

There's indeed a need for a Dypsis plumosa damage thread.

This December, we abruptly had a 26º F (-3.3 C) freeze, followed by 28 F two weeks later. Lots of wind, no frost. Mine has serious leaf damage, but will unfurl a normal new leaf soon. It's in the middle of the photo--the palm with white leaf bases--with a pair of tall Carpentaria acuminata to the right and an Archontophoenix tuckeri to the left. Back of the Dypsis is a mass of Sabal minor and Coccothrinax argentata.

[Dave-Vero]

My D. plumosa already has one new leaf, showing no damage from cold. A second is set to unfurl. Several older leaves are nearly undamaged, somewhat younger ones have dead leaflets but green petioles, so I'm leaving them on the assumption that they're manufacturing food.
