I think there is a lot of hype on the idea of vertical gardening. I believe a lot of it is in the experimental status and in many cases some are successful in creating the ideal medium in handling the plant material.
At best - its always good to choose plants that are epiphyte in nature (plants that grows on trees) I had discovered that Tradescantia can do very well as an epiphyte - specifically Green Wandering Jew (Tradescantia fluminensis) and Bolivian Jew or Turtle Vine (Callisia repens)
These had done so well for few months. (The plants are layered on a wire)
All they need is daily watering.
I had added Zebra Tradescantia together here and it is doing fine.
(Also Purple Queen & Bolivian Jew - below)
The Purple Queen Flower.
These are famously known as Airplants.
(Spanish Moss and the other two Tillandsia which I really not sure what species are they)
One thing for sure - they had grown bigger compared to the size I had first purchased them.
These are my orchid collections.
All of them are fastenened on wood and some wrapped with coconut husk.
Most of them are doing fine and to a certain degree some are slow and dormant.
I really not sure what are their specific species names.
Somehow I'm still waiting for the majority of them to bloom to be sure what exactly are they.
Regardless - I enjoy looking at them in their well defined roots and leaves in their natural form fastened on wood and branches. And it really save a lot on the fact where I really don't have to worry about root rot or over-potting problems.
Finally - Im still blooming Ground Orchid at its very prime age. Two of its spiked had dried off. This is the last one. I'm still secretly hoping new spikes to spring forth. I guess it got lot to do with correct fertilising regiment which I'm very much neglecting.
Blooming since February.
Hope you enjoy viewing this Vertical Gardening Concept.
