Brugmansia Zuni Yellow Spider
Firstly I'll explain the name, the hybridizer is from a place called Zuni, Virginia US of A.
Yellow is self explanatory and the spider is because the tendrils also known as twangers are well spidery looking. It also smells very nice.
It's abit of a shape shifter this one as it can produce triples or appear stuffed. This was Zuni last year in my garden.
