In real life bottle gardens are variant of the terrarium, and as long as the plants we put inside have the right soil, sufficient light and moisture content they will long last. In 1829 Nathaniel Ward a London physician discovered accidentally that some variety of plants were able to grown on a closed glass. Water evaporated from the leaves during transpiration condensed inside the glass being then absorbed by the roots. This concept was adopted by Victorian gardeners and had lots of enthusiasts.
At home I have always a bottle garden, the plants I put inside lasts around three years, after that I have to change them. So I was glad when I found these miniature Bottle gardens at the Madrid Fair, now I have to decorate them - the final destiny is my future greenhouse, and here they are:
The two garden bottles together with a few containers for miniature gardens
A detail of my future greenhouse, everything is in preparation
Another detail, I think I need a bigger greenhouse because I have lots of nice things related......
Everything is out of place awaiting for the structure to be painted; one more project to add to the list of the unfinished ones.....
