Gardeners' Notes:

At first I saw several nice clumping specimens in a landscape, and asked for some seed off them. The seedlings came up fine, but were all green leaved at first, so I gave them all away. Couple years later at the one gallon size some started showing the silver color. Bummer. Moral.....be patient.
The gray color didn't appear right away on the baby leaves.
So then I went to HOME DEPOT and just bought a larger size specimen for 45$ !

I have been happy with my Moroccan Silver fan palm. It is thriving without protection, except that is sited favorably on the southeast side of my house. There has been no damage the last two, albeit mild, winters.

As a huge fan of glaucous (blue/silver) plants, this is a gorgeous palm, so let me point out that my Neutral rating only pertains to growing it in my particular climate (rainy SE Louisiana). I have to give the exact opposite comment as that of JoeCastleHayne. My green ("regular") C. humilis all do fine here in any weather conditions, but my C. humilis argentea all keep getting spear rot, and have barely grown after a few years. A rainy winter will cause practically every single spear to die and rot away, and they can only be (sometimes) nursed back to recovery with vigilant dousing w/ hydrogen peroxide.
If I lived in more of a true desert climate, I'd probably have at least 5-10 of them in the ground, but for the Southeast U.S., stick with the green form. Mid-size glaucous palms... read more

Reliable with extensive protection in western Kentucky. From what I have seen, it will nearly defoliate at single digit temps if not protected. Fortuntely, as a clumping palm, even if not protected will regrow nicely in spring after established.

I am growing both the regular green, and blue forms of Mediterranean fan palms in NC zone 8a. The blue form has proven to be much more cold hardy for me. Both receive crown protection during wet winter weather. The green form has been defoliated and the spears have pulled each winter, while the blue form has shown no winter damage at all. However, the blue seems to be even more painfully slow growing in comparison.

Well, actually the 'cerifera' form (I think that's the same than var. argentea) of Ch. humilis is not an European palm but is originating from a valley in the Atlas Mountains in Morocco.

i got a three gallon for 13$!!!!!!!!!!!!!!!!!!!!!!!!!! wow haha very very beutifull blue/white and cold hardy to 8a at least .

In my opinion the cold hardiness of this plant is overrated, I would be cautious below zone 8b unless you had a very warm microclimate.

I just received some seeds forthis palm, which I intend to plant today. I was told the color was as good as that of the Bismarckia; your pictures seem to confirm that. Do you know how old those seedlings are?

Basically the same plant as Chamaerops humilis, except bluish-silver leaves. Some varieties are really silvery and incredibly ornamental. Silvery forms seem to be a bit slower growing than normal Chamaerops. Recently (in the year 2006) this form of palm has become much more readily available in southern California and you can get a robust 15 gal palm for only $60 (5 years ago it would be worth $200 or more). I have also seen them now at lots of local 'regular' nurseries. I look forward to someday seeing them used as landscape palms here in So Cal.

One thing I have discovered is growers often get seed of this plant, and they very often turn out to be normal green plants. I had heard the excuse that they are green now, but will blue with age. Not knowing anything at ... read more
