Sounds like a valid idea Jo Ann. Its good hearing from you here.

I'm astounded that you are already thinking of working on the figurative concrete clothes line Jean. I'm still waiting to see pictures of your earlier creations!

Coralline algaes are what grow on objects in the sea and are the seas version of lichens to me. I used to do true reef tanks with corals and living sealife in the restaurant in New Orleans. I grew to understand how colorful coralline algaes could be and also how costly it was to do that hobby and share the tanks with the public when the storm Katrina came through and forced a month and a half evacuation on us and losing all the critters and living things I loved in those tanks....... The looks in them are in my memory. I don't do reef tanks anymore as now I realize while I was very good at them for a point in time, it is a wealthy mans hobby.
This pot and my sea themed pots are an inspiration from those days...
Both sections of this planter have drain holes, and I am hardening off some echeverias. The beauty berries are about done and I incorporated a bouquet with one of my aluminum can flowers for effect in this shot to show the versatility of these pots. They can be planted and bromeliads, succulents, and those families would be my personal choice yet the sky is the limit on faux or real bouquets in containers then isn't it?
I'm sure I'll be chattering about all the other cosmic concepts I'm dreaming up somewhere soon............................Bee - Bo - Bop!
