Re: Species suited to a water wall

---

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 right.

 

Cali is 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 downtown Cali.  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.

Hi.

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.

Cheers
