A bigger one.

Not much living tissue inside.

This member of the Asclepiadaceae* family was given this name by R.E. Woodson in 1941. It's from Mexico, growing in well-drained soil with some water and a bit of sun. The flowers are brown and smelly! Can only be reproduced by seeds. I got mine from Botanical Garden in Copenhagen 2004.

*This family might been incorporated in the Apocynaceae family now.

The flower are two centimetres big, and can be really dark.
Attracts by the smell of rotten meat!
