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
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
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
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.

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.
