I was visiting Bonito city, a fabulous tourist attraction in Mato Grosso do Sul state, when I found this plant in a vase in an hotel. I took a little branch and I cultivated it. this is a kind of cacti that survives in the top of trees, there are many especies of these plants in Brazil. Here we have a view of the part of the big cascade of branches and white flowers.
This image is positioned in the horizontal, but the leaves are naturally in the vertical position.
That's an interesting plant, Jorge, it looks nearly a little plastic-y. As you say, it is from the cacti family so very often they look a bit unreal when the flowers push out. It does have a festive approach, flowers blooming from such a plant is always a gift and a pleasure. It fits Christmas :-)
