Identification: Glossy Lime-Green Leaves like Plastic

The following was received via email:

I live in the states, Florida, never been to a Botanical Garden... now
this web site made me curious enough.

I was hoping you might know the name or how I can locate one?

I had received a clipping from a plant the most Unusual Plant I ever
seen I had it for three years I kept it indoors and it grew very so slow
it bled, Looked like milk film. Leaves was bright glossy lime green
looked like plastic it was a vine that intertwines with each limb only
grew leaves at the tops it was narrow leaves lime green color does not
bloom everyone who saw it thought it was fake.

the strange part the leaves would change colors when the temperature
changes.
The plant died in the frost.
I really would like to locate it again and never depart again.
Sincerely Plant Lovers,
Matthew

 

Hi Matthew,

I'm thinking that maybe you had a Euphorbia tirucalli - pencil cactus, which isn't a cactus at all. Is this your plant?
