Trachycarpus martianus

[Exotic Life]

Hi,

T.martianus is a great one! I have since a week a little seedling from it, i will let it grow too a bigger plant and then i'm going too plant it in the ground. Trachycarpus is for here one of the best growing species, and also the hardiness is great. I have also seedling latisectus, young wagnerianus, young real princeps, several fortunei's. Last year i killed my nanus

I think That Takil, ( I'm referring to Rome Takils, the two at Rome University , and the One at Rome BG)is one of the most beautiful of the species

Martianus, Wagnerianus , Latisecticus etc, lost its charme when becoming adults.

Instead Takil , IMO, becoming very beautiful when adult

We have just to wait for see what will happen with Princeps fromGolden Lotus or Stonegate

August has been very hot in Walnut Creek in Northern Calif. We have just had 5 days over 100 F (38 C) and one day was over 108 F (42 C). I have a T. nanus and T. princeps in containers growing on my deck. The princeps looks fine, but the T. nanus has suffered from the heat. I think if it were in the ground and the roots not subjected to such heat it would have faired better. I think I will plant them both before the summer heat slips away.

None of the Tracheycarpus enjoy such sizzling heat and I expect another burst of growth when it cools down. All of my Parajubaeas in containers and in the ground have faired well. Brahea decumbens and Butia archerii seem to love the heat and are growing well.

Dick-maybe its the humidity here that makes the difference, but I have never seen my Trachys slow down due to heat. We had an especially hot summer last summer-many days over 100 or close to it, and much earlier that normal-and that is actually par for the course for at least one month or more each summer, and all of my Trachys did well-didn't seem to skip a beat. Before reading what you wrote-I would have said that Trachys can handle the heat well. Maybe not all year-I can't say that because of our winters here, but heat we have. Do you think the humidity helps/makes the difference in performance in the heat?

That picture of the martianus looks great! Very pretty. I haven't seen any of those around here. I have very healthy small takil and wagnerianus that I got at the SE PS meeting here this spring; I will put those in the ground next spring, and I am also concerned about nematodes/heat/humidity conspiring against me. So far, no apparent wormsign in the pots. I haven't seen many of the Trachy's here except fortunei, and I have wondered if it may the the nematode problem, made worse by the summer heat and humidity. Obviously, we have more than our share of all three. I would love to put a martianus in a trio of varieties in my yard, even with the risk. I'll certainly be on the lookout to get one of the first in town.

I would say go for it... I am growing T. martianus here.. I have one in the ground for many years --- under pine canaopy - I put in sevaral small ones I got from floribunda a few years ago. You can grow them here. T. wagneranus grows here also... some of them die suddenly but mostly thrive.. I have lots of T. fortunei as understory of a pine forest. They are 8, 10, 12 feet tall

some have died suddlenly over the years but most of them thrive.

Best regards,

Ed

Trachycarpus is very susceptible to nematodes on our sandy soil. T. martianus and T. wagnerianus seem to be the most sensitive. I have always lost them. I have found a location where T. latisectus is growing well so next time I get a T. martianus I will plant it there.

Here is the last T. martianus we have, you can see how lovely it is !

And a T. latisectus which is in a favorable location, this is where I will put T. martianus the next time.

Here is a scientific correspondence from Michael Lorek. Some of you may have red it already.

First important information: according to the author, latisectus is not a species , but only a subspecies called martianus ssp latisectus.

Then, the description of ssp martianus and ssp khasianus shows the opposite of what is admitted here and by Pacsoa: the palm of ssp martianus (aka Nepal form) is orbicular, the palm of ssp khasianus (aka Khasia hills) is flabelliform.

At last, in the key to the subspecies, a line of the text with the name latisectus could be missing, and another ssp sikkimensis is mentioned . Are they four subspecies instead of three as said above in the text or is the name latisectus replaced by sikkimensis?

Is there any controversy or are those conclusions admitted? What do you personally think?

Sikkimensis was changed to Latisectus a few years ago now.

Here are my two, first one is Latisectus the second is Matianus.

does anyone has any idea wich one this is? some think it is T. sp nova (green princeps) it's very slow, 1 1/2 leaf a year

i agree with T. wagnerianus. they can handle the worst winds without damage and are very cold tolerant.

here's one of mine, this one gets hits with every storm but never showed wind or cold damage

Wow. Ive never seen a Trachy like this one. I don't know anything about the "green" princeps though....if this is it, I want to try it. It reminds me of Rhaphis multifida... Does anyone know about T. sp nova (green princeps?) Nigel are you out there?

[ghar41]

I did find this...

[kristof p]

there is not much information about the sp nova. is it a hybrid or a new species or just a variation of T. princeps? some of them do have white undersides but on an older age. i also heard that these palms are in danger because the locals remove them from their natural habitat. they fear that they wil hybridize with T. princeps which is more valuable for them on the market

more information about sp nova would be very welcome.

i have my doubts about the weird Trachycarpus in my previous post beeing sp. nova. it is one of the slowest palms i have while sp nova grows very fast. i have a couple of sp nova growing in the garden an the leaves look differant. sp nova has more and thinner leaflets. of course there could be as much variation within sp nova as there is in T. fortunei??? ...if only we had more information about the sp nova....
