This native of the Caribbean is bat pollinated and so its flower color and fragrance are at their peak at night. White to yellow flowers are borne in succession along the length of stem to be followed by large 'dragon fruit'. This species is top grafted onto saguaro relatives at about 4 foot in height where it's naturally sprawling growth habit creates a cascading effect. Plant in full sun, very well drained and low nutrition soils and stake as needed to direct the sprawling stems.
