  Anthurium pedatatoridium
From: crogers at ecoanalysts.com (Christopher Rogers) on 2008.06.04 at 10:03:58(17734)


I have had a specimen of Anthurium pedatatoradium for about three years. I
propagated it off of a specimen at the University of California at Davis,
which was collected by Tim Metcalf in southern Mexico a few decades ago. It
was slowly dying in my greenhouse, and then I had to move. I have been at my
new residence for nearly three months, and the plant really likes my new
greenhouse. It has put out one new leaf, with another on the way, and has
pushed out two inflorescences, one of which opened today. I have attached
the pictures here for your perusal. One picture of the entire plant, one of
the newest leaf, and one of the inflorescence, with the spathe limb just
starting to bend away.

I keep it in the coolest part of the greenhouse, with high humidity, lots of
shade, and only a splash of water every day or so. Under these conditions at
the University the parent plant was growing like mad. In my old greenhouse
my plant was barely hanging on. In the new greenhouse, it could not be
happier. Go figure.

Does anyone else have any experience with this species? Is it common in the
hobby? I ask because I have done little with the genus, mostly focusing on
the tuberous taxa.

Happy days,

I have had this species for a number of years and it never does well. It
almost dies every year. I have a number of small plants but none that are

Hi Christopher,

I have had a little experience with some of the Mexican Anthurium species, and get cut back stems of different species time to time from a friend who lives in Vera Cruz. He is into plants and travels around his area and Chiapas collecting when he get a chance.
I've have had good luck, so far, with everything I have received from him.
When I first get the stems, they are totally void of any roots or leaves, and actually look like they have been shaved with a machete.
At first, when I got my first shipment, I thought 'good luck' getting them to grow, but decided to try rooting them in the largest perolite(sponge rock #4) that I could find available. To this I add hardwood charcoal, that I smash with a hammer to get small pieces, and add that to the sponge rock. I have had about 95% grow roots and leaves treating them this way, which is far better that I ever thought would be possible.
I know Mexican Anthuriums do like it a little cooler, but they seem to thrive for me here on Oahu, Hawaii, where my minimum night time temperature never drops below 68 degrees Fahrenheit.
I like to place them where they get a lot of air circulation, and good light(bright shade). Also clay pots seem to work well.
I water them normally during the late Spring and Summer, like my other Anthuriums, but the other times of the year I only water when they appear dry on the surface of the potting soil.
I have found out from experience that if I water them before they are on the dry side, during the Fall, Winter and early Spring, they either sit or begin to rot.
Usually if they are sitting without putting out new growth signals to me that the roots are starting to rot.
For a potting soil, once they are well rooted and starting to grow, I use a very loose mix. I try to incorporate twice as much large sponge rock into the mix as I do the peat moss, orchid bark and charcoal mixture(using larger hunks of charcoal at this point), so the mix I use would be 2 parts sponge rock, 1 part peat, 1 part orchid bark, 1 part hardwood charcoal (do not use briquets). I want my soil mixture to be extremely well drained and loose.
If I think a Mexican Anthurium's root are in trouble, I un-pot and remove the problem roots, treat with root tone and repot back into the sponge rock/charcoal mixture like I first started with to root them out.

Hope this helps you and anyone else interested in the Mexican Anthuriums.

Thank you, Windy!

I will keep mine a little closer to the circulation fans. Hopefully this will keep it cooler and better aerated. It sounds like I need to keep the media loose. I have used pumice, sphagnum, fir (orchid) bark, sand and peat. It sounds like I need to make it a bit more epiphytically friendly. Hmm. It sounds like I need to move it to my son?s orchid bench . . .

I also have Anthurium pallidiflorum, which also seems to like to be cooler. My plant struggles in the heat of my greenhouse but keeps growing and produces the odd inflorescence. I moved one of the University plants (with 30 cm leaves) into the cloud forest room, and it now has 1.5 meter long leaves and lots of inflorescences, which have produced berries, that I was able to germinate. These are really fun plants. I obviously need to try more species! If only I had more space in my greenhouse . . .

Happy days,
