Just thought I'd share my related photo. I've got it hanging outside my window, and the plant has grown a lot in such a short span of time.
I got this from the bag of dried leaves I stole from Ayala Alabang. Someone tossed cuttings in. This is probably related to the local ulasiman that is medicinal, which bears yellow flowers. You can eat the leaves too.
Too early to tell if it's the same as Diane's moss rose! Or are they one and the same? I'm confused.
