Vertical garden with orchids

I'm still prototyping vertical garden pockets. In the last post, you saw the apparently empty pockets. One set of Napa Valley poppy/Evening Primrose/Wild Blue Flax seeds are sprouting:

I installed a new row, this time with two pairs of screws in drywall, and outfitted them with orchids from a friend's personal collection and rescued from other friends.

I removed the bamboo and plastic rods that give orchid flower spikes their artificial erect position; they're epiphytes so they don't need to be tulip-shaped. This way they can expand across and out from the wall.

Most Americans I know have trouble keeping orchids in bloom. This is part personality mismatch, part misinformation, and part poor commercial design. One of the orchids was seated in the typical plastic root cup inside a sealed pot full of extra mulch and moss. There was an inch of stagnant water at the bottom when I got it. No wonder it had lost its flower spikes and the leaves were starting to turn!

I think orchids will be perfect for pocket gardens because they require the occasional minute-soak, drain quickly, and spread over vertical surfaces.

Thoughts?
