trachycarpus spp silverdwarf (Guihaia argyrata)

[bikoro child]

Hi, I've seen this one on your site Garry can ' u give us some info about it?

Salut, j'ai vu ce palmier sur ton site Garry peux tu nous donner quelques infos sur lui?

It seems to have a waxy leaf like T Princeps ,could it be a T Princeps nanus (dwarf) ?

On dirait qu'il a une feuille très pruineuse comme le T Princeps ,est ce qu'il pourrait s'agir d'un T Princeps nanus (nain)?

I guess = T. geminisectus
That's what 'dwarf silver' generally means.

Hi bikoro
The silver dwarf palm you saw is not Trachycarpus ,but Guihaia argyrata. But previously it was called Trachycarpus argyrata .When we first found them, we thought it was a trachycarpus and later confirmed it was not. G.argyrata grows on limestone mountain with glittering snow white stuff to the underside of the leaves like T.princeps.
Both species are growing in the stone mountains .But T.princeps is more cold hardy than G.argyrata which grows slower than the counterpart.
T.princeps grows on the cliffs at altitude of 1600-2100 m facing the Angry river. What is famous about this palm is its snow white powder at the backside, very charming and elegant.
It is tested to be very cold hardy as T.fortunei.
Both are interesting species to grow.

C'est formidable d'avoir, grâce à  Garry, toutes ces informations sur des trachycarpus moins connus, quelle merveilleuse famille!

Hi Gary
You say Guihaia argyrata is not so cold resistant, but have you an idea of its hardness?

Salut Gary, tu dis que Guihaia argyrata est moins résistant au froid, as tu une idée de sa rusticité?

Hi Gary,
I think the hardyness of Guihaia argyrata is to about - 12°c. I know just two Guihaia in France and both are very slow growing, but they look hardier than people think.
The biggest is located in Menton, (french riviera) and is come from a swiss nursery, when it is in switzerland it took hard freeze during it's seedling stage.

J'en ai un en minuscule en pleine terre depuis pas mal d'années. Il ne pousse pas, certes, il est d'aspect minable parce que quelle chose ne lui convient pas, mais du -6°/-8° ne lui fait pas peur.

J'ai des plantules en pot, âgées de 3/4 ans, croissance très lente mais restent dehors l'hiver sous ma miniserre non chauffée (ont pris -4°C un matin l'an dernier, en pot, la sonde est placée à  proximité, puis d'autres petits gels par la suite).

Yes, G.argyrata is a very slow grower as compared to T.princeps which I think is medium one. It has only 3 -4 leaves after 2 years. G.argyrata has a brother called G.grossefibrosa also growing on the limestone mountains. The difference between them is that G.argyrata have shorter petiols with white fur whereas G.grossefibrosa have longer ones with white powder at the backside.
I think the cold hardiness for both species could be around minus -7C to -8 C as they are originally from not so cold area in South China where it goes down to -5C or so. The hardiness has not yet been tested by us. The seeds are much smaller than those of T.princeps.
