The plant bears clusters of golden yellow blooms along the vining stems during summer months.

Individual blooms emerge successively over a period of weeks emitting a rich, heavy fragrance during the day and night.

The plant can be reproduced by cutting or seeding and grows in airy soil in bright sunlight.
