If we are talking species - There is only the one; Chamaerops Humilis. There are only 4 accepted variations : C humilis car humilis, var Vulcano, var ARgentia, and cerifera. They are extremely variable, and there have been many name for these, but there are only 4 accepted variations of the species. It does seem that the seedlings will be just as varied as well.

Cerifera isn't accepted. It's a synonym of the original name Argentea. I wonder why we been callin it wrong all these years?

Here's what some stuffy 😆 British site says about it : http://apps.kew.org/wcsp/qsearch.do?plantName=Chamaerops&page=quickSearch

Damn taxonomy.... lol. Most of the reliable places ive seen call it cerifera.....

Cant be as bad as bamboo taxonomy. I ordered some seeds called "fargesia spathacea" (turned out not to be it). I tried to find information on it but was taken on a month long journey down the road of misnamed bamboo. Found out a common type is misnamed, as well as many other ones ive been looking up on. Fargesia rufa has a good 5 or 6 names. If i remember Fargesia rufa is supposed to be called Fargesia spathacea or F sp. "rufa".....

Its like going down the rabbit hole... "Go ask Alice, I think shell know".

Pics of the palms I found on sale in Sioux City, IA

$50 for the Christmas Palm $25 for the Silver European Fan Palm. They had more Christmas, but all doubles and not quite as big. They also had a lot of TALL Queen palms as well for $50 each anywhere from 8-18 ft same price.

After getting the "silver" home, I think I see what the difference is. The underside of the fronds do have a silvery color to them, where as my other one I have that is "Green" is green on both front and back.

Great finds! Glad you got to get them. Both look healthy too. I guess the "Silver" is just something the nursery has printed on the tag, huh? Whatever you call it, it's good-lookin. I think one of my green ones has a silvery white underside. It's composed of fuzz on the underside that rubs off.

The fronds have a silvery coating on the undersides, so guessing that is why they call it that.

mine does to but it comes off easily or with time..wish it held it till the fron died

Yes, the coating of Silver does rub off, much like the "blue" on other palms. Still, Palm looks different from the Green version. All potted up in a bit bigger pot and looks good.

Looks great. "Silver" med fans must be popular in the trade right now . I just saw a ton of them in Ft Worth at a really cool nursery. The guy said hardy to 5F, think that's a huge stretch myself. Maybe out of the wind, bone-dry 5F.

Krisk, There is a member here that lives in Utah and has a really nice European Fan palm that he over winters and it sits out in the middle of his yard in a raised planted area.

Is it ArcticTropical? That guy is crazy cool with his ability. His stuff is heavy illy protected, though.

Can't remember his screen name is, just remember the great looking European fan palm and amazed he could over winter it as isolated as it was.

I'm at my limit for electrical outlets and what they can handle now so can't really add more to it.

You can always add more insulation so you need less wattage....
I am pretty much maxed out here in my upstairs Apt with cords
running downstairs but another layer of bubble wrap on p-protection could mean
palms that have grown over summer etc-don't necessarily need more lights/heat...
and in some cases less-I think I only had 7 C-9 lights in one of my Trachy covers
that is maybe a few gallons short of being trash can sized.

For each over wintered in the ground palm they get 1 6ft heat pipe tape around root ball (has built in thermostat) and 1 string of 25 C7 Christmas light string plugged into thermocube, so neither use much power, it's just I have them in series on a house circut. Also have 3 ponds that I keep water flowing in them and keep them from freezing with a stock tank heater in each one.

Since last winter I've added 3 palms to collection in the ground. 1 Windmill 1 Mexican Fan Palm and as an experiment......Pygmy date palm(I know, a stretch but they are a dime a dozen at $10 each, so why not? lol)

Last winters electrical use jumped our monthly power budget by $80 a month. Wife PISSED! but she'll get over it...they always do. 🙂

Lol. I bet your stock tank heaters did the electric bill damage. Electric resistance heating is expensive. My heatpump has an electric secondary stage. I can always tell if it's been particularly cold by the increased electric usage. Fortunately it doesn't call for the secondary very many times during winter.
