As it happens, I just returned from Cali, Colombia
where my host Alvaro Calonje took me to see a wet wall he had made in an
upmarket business place. In the attached picture, Alvaro is standing on the
about 1,000 metres above sea level but nearer the equator than the DR. Temperatures
are definitely cooler than where I am at 250 metres altitude in Grenada, 12
degrees north. For instance, I saw spathiphyllums planted in full sun in
But it never gets anything near as low as 6C !
I don’t think there are any aroids on the wall
except the white and green form of Pothos. There are a profusion of
alternantheras and types of ground cover, begonias, vinca, (the plant known as periwinkle
in temperate gardens), ivies, maidenhair ferns, peperomias, selaginellas,
zebrinas, and creeping plectranthus would be a good one too.

Subject: [Aroid-l] Species suited
to a water wall
A friend advised that this list sometimes discusses water walls and the species
that suit them.
I have a new water wall. It's about 5 feet high and about 20 feet
long. Rocks are already turning green after just a week of water including
several dry spells (to fix leaks!). I live at 1400 metres above sea level
in the Dominican Republic so day temperatures can be as high as 32C (often
cooler) and nights drop to as low as 6C. The wall is exposed to strong
sunlight for several hours a day. The water is neutral and direct from a
river. The rocks are probably neutral (but may tend towards alkaline - I
must test this).
If anyone can suggest specific plant species or varieties (not necessarily
aroids) that would be either interesting or attractive, I'd be grateful.
I'm relatively knowledgeable about carnivorous plants and not new to
specialist gardening, so I'm looking for something a little more helpful
than generalities (so for example, being told that "ferns" are good
would be no real help).
Thanks for any suggestions, especially if replies are copied directly to me.
