At this point it looks like all of the crownshafted palms are D-E-D. There's a chance that a couple will make it, but really only the clustering ones are going to come back from the roots. Most of them just aren't hardy to the low 20s, and some struggle to survive a 30F frost here. I did some more cleanup tonight in the SE corner of the house. There's a bed that's anchored by a Pygmy Date double, with an Encephalartos Sclavoi x Ituriensis directly in front of it, and a bigger unknown Encephalartos on the left, and a not-really-visible Encephalartos Gratus x Laurentianus behind that. I pruned almost everything out of this bed. I think everything here will survive, despite the burn. I left the Arenga Hookeriana dead stems in place, as the suckers need a bit of shade. I'll chop those later, after the Pygmy grows a few more leaves. Just to the left of the Pygmy Dates (on the other side of the pathway) is an Elaeis Guineensis burnt to a crisp, and on the left a similarly toasty Arenga Pinnata: After pruning the Elaeis had a double spear pull with a rotten bottom, so it's chances are very slim. I poured about 8oz of hydrogen peroxide down to fill the entire bud. This seemed to kill off the bud fungus in two Bottle Palms, so I'm trying it again here. You can see it has one frond with a green rachis/petiole...everything else I cut off was dead and rotten inside.

I haven't done drenches of anything yet on any of the trees. I did cut the one much farther back today and that's when I saw all the white powdery looking spots all over the fronds and the darker brown and bronze looking colors on the green that is growing, which made me worry that its all infected now or something. My one tree now looks closer to yours in terms of how it got trimmed so I guess I'm headed in the right direction.

This plant needs to be potted up badly. I'm willing to sell this plant for $1100. Socal pick-up only, or perhaps I can meet some of you out of towners half way (within reason). This plant will be put into a box the first weekend of April and will no longer be available for this price. 9+ X 9+ inches of caudex, super blue, sex unknown.

@Skenny I personally wouldn't bother with a copper fungicide at this point. The only real risk (IMO) to the palms is a crown rot. If you've done a crown drench of hydrogen peroxide, copper, Daconil, or Mancozeb, then it's just going to take a while to grow out. Spraying the whole palm with copper might not be any benefit, and copper fungicides are phytotoxic in big doses. I'd mark the newest spears with a sharpie while miraculously avoiding getting skewered by the thorns. If it's moving, you are in good shape. As far as pruning, that's pretty much what I did to my double in the backyard this evening. I cut any totally dead fronds. I cut the ends off of ones where it was green rachis/stem/petiole. I just picked a spot a few inches further out from where it went from green to brown. This is before: And after: I left the top ones on the left trunk, even though the ends were totally dead. That's only because I didn't really feel like getting out a stepladder to reach them.

Yeah, Redwood City Hills. It can get quite hot, but pretty close to the same as San Carlos. The relative humidity is generally pretty low, so I worry more about burning than the average palm talk member.

Asterogyne martiana is apparently an easy grower for me, this one has done outstanding this last 6 months despite a chilly winter, even in the greenhouse. There are others that look good but this one I really noticed recently after moving it.

Those get massive!!

There's plenty if you consult the South African society or the SA members on facebook Cycadfriends page. They can tell you all about it.

I really must get to Hawaii. I know that overwhelming feeling when you visit an amazing collection!

They grow them in the UK so they should be fine for you. The ones in the UK remain pretty small and grow slowly but they get the freezes that knock them back to the roots. I would expect that you get no frost so albeit slow growing, they should size up over time provided they get enough water.

What is the difference between T. rosea and T. heterophylla?

I never doubted you, it's that there some pretty distinct differences across the city. Just like that NW corner seems to get the worst of the storms every time. They get a tornado and I get a few sprinkles. I've been so tempted to film the radar because I can't even tell you how many times the rain will literally split around me to north and south. The lake seems to be some sort of blocking feature. I'm hoping we get rainier as the summer goes on, because its already worrying.

Agree with Satakentia liukiuensis

All the logos look like Cocos nucifera to me (even the Sabal advert) which, while present in the area are far from common.

This is Tabebuia heterophylla, which is the most widely grown Caribbean native Tabebuia in Florida (Tabebuia aurea is from Brazil). It's a great tree for south Florida, can bloom over a long period of time and does not typically go fully deciduous. It has a naturally compact crown with columnar form and doesn't ever get massive. I don't think it's frost hardy so restricted to south Florida.

Oh no, you have already drenched the soil!

I would think if it were possible Encephalartos woodii would've changed to a female decades ago....

at a botanical garden it is expected that there will be plants everywhere, and people who do damage there should be frowned upon without question… imo

Not Carpoxylon. I’d stop short of saying this is a 100% positive ID since the lighting makes it a bit difficult, but looks like Satakentia liukiuensis to me.

Saw this specimen today that is still blooming. It also had a passenger on it's trunk.
