If you have one and want to know what makes them happy,
we have one in full sunlight and several in the shade.
(this guy is actually hanging from our patio umbrella)
The full sun one is HUGE, the others are still happy.
One was inside for a while. It is much happier outside, although
it grew very long thin pads looking for food while it was inside. Now
that it is outside it is popping out all kinds of thick
little pads along the lengths of the woody thin pads.
Makes for a very interesting plant.
One thing they all have in common is they love water.
You may think since they are cacti, they like to
be dry, but they are definitely jungle plants.
More about their history, and one of the reasons I love them
so much see this photo of the day.
