I planted seeds in flats in March and moved outside end of April. I have three in large containers on trellises and keep winding them around. The others are on shepherds' hooks in the garden mixed with Cypress Vines to provide flowers for the hummers in the daytime and flowers/fragrance for the people at night. The luminous flowers are 6" or more across with a trumpet about 5 to 6" deep. The fragrance is subtle and gentle. The flowers last only one night, but the vines are consistently putting out more buds. A truly remarkable vine that I want to have every year from now on. They require daily watering in the containers in the heat.
