I got this Stanhopea orchid many years ago as a two bulb division, it was a
gift from a friend. I planted it in a
basket filled with small pieces of coconut husk. I watered and fertilized it weekly. Under the climatic conditions in Aguadilla
the plant grew slowly. Originally this plant was in a garden of my
mother’s house, which is in Aguadilla, in the northern coast of Puerto Rico and
about a mile from the Atlantic Ocean.
This part of Puerto Rico is characterized by often windy conditions as
well as warm to hot weather. In these
environmental conditions the plant didn’t do too well, probably because I was
watering it less than it needs in this warm climate.
When I moved to Arecibo, to a
location about 1,000 feet above the sea, the plant started doing much better. To me the main reason is that in this
location it rains more than in Aguadilla, but maybe it helps that the new
location is cooler. During spring, summer
and fall the media in which this orchid is growing stays moist just from the
water it gets from rain. During some particularly rainy periods it remains wet for
weeks or even months. Sometimes it
rains so much that the media becomes absolutely waterlogged. I these very rainy
times, here and there, patches of white cottony fungus appear in the media. However the plant doesn’t seem to be bothered
by the fungus. The fungus dies off when
drier weather returns. The climatic
conditions in this part of Arecibo are more moderate than in Aguadilla and it
hardly gets as hot. Only for a few
months in the summer the temperatures in my location in Arecibo become hot
during the day.
In Arecibo, this orchid grew into
a large and heavy plant, but it would not bloom. The plant was moved to a sunnier spot than it
had been growing and it eventually bloomed.
I thought I had found the perfect spot for this plant among my pendent Dendrobium, but this conclusion was
produced by the fact that I moved the Stanhopea
with them in the spring. Because of the
movement of the sun along the horizon during the seasons, the Dendrobium shadehouse is sheltered from
exposure to full sunlight for most of the day during spring and summer. But in fall and winter, the shadehouse
receives full sunlight for many hours.
This is ideal for the pendent Dendrobium
but the Stanhopea could not cope with
so many hours of direct sun. As a result
of the increased exposure to sunlight the Stanhopea
lost all its leaves, happily the
pseudobulbs were not harmed and the plant recovered quickly. I had to experiment a bit to find the right
place for this plant, one where it would bloom well but not get its leaves
sunburned. Presently my plant is in a
place where it gets unfiltered sunlight until 10 am and dappled sunlight for
the rest of the day.
In my garden this plant blooms in
the summer, however it has also produced inflorescences at other times of the
year, even in December, at the start of winter.
For some reason, every year it aborts one or two inflorescences when
they are about half developed, it is not clear why that happens as it usually
has other inflorescences at the same time that develop normally. The inflorescences take six or seven weeks
from the time I find them poking out of the media to the time the flowers open. The inflorescences my plant produced carry
from four to seven flowers. The flowers
last around three days. The fragrance is
reminiscent of chocolate. My plant
cannot be classified as a prolific bloomer.
The media in which this plant was originally planted decayed
a long time ago. The plant now has a
root ball that grips the remains of the bark that I used the last time I
refreshed the media. Any kind of
repotting is out of question as Tthe roots grow in all directions, sometimes
even upwards, any attempt to remove it from the basket to change the media
would result in severe root damage. The
plant produces new growths along the edges of older pseudobulbs, which are on
top of the basket. But in early in
2013, a new growth popped out from the side of the basket, about two inches
under the top of the media. This new
growth has been developing normally, and even produced an inflorescence in
spite of being smaller that the full grown bulbs on top of the basket.
This orchid is doesn’t need much attention with two
exceptions. One is that it resents
underwatering, the other is that the basket where it is growing is a veritable
weed magnet. In the rainy season I have
to weed the basket to prevent the weed growth from becoming too heavy. Among the most persistent weeds are the ferns
and begonias.
In Puerto Rico Stanhopeas have never been particularly
common orchids in local collections.
Having said that I can attest that particularly knowledgeable growers
have been growing them for many years. I
saw my first Stanhopea plant at an open house of the Universidad de Puerto Rico
in Mayaguez about thirty four years ago.
The plant was the property of Dr. Rivero.

Ricardo, parabéns que show de Stanhopea e fotos.
abraços e boa noite
Dear Sir,
I read your article closely as I m one Orchid lover and Conservationist. Regret to say that all wild grown specimens were vanished slowly just after 2007. I think, was not due to impact of Global Warming. We should try for its insetu conservation at Wild.
Thanks a lot for your closed observation of this plant.
