The germination of handkerchief tree seeds will take about 18 months, but the saplings can grow rapidly.

Plants produced by layering of the stem will flower before the trees grown from seedlings as the plants have already crossed the juvenile stage. The ideal time to make the cuttings is after the leaf fall and just before the buds appears in spring. Select the healthy shoot grown in that year and remove the soft tip. Cut pieces of 15-30 cm with at least one bud. Dip the lower cut end in rooting hormone and plant them in sheltered areas with well drained soil in the ground or in pots. At least 2/3rds of the cutting should be below the soil. Leave the cuttings in place till the next autumn and once the cuttings develop, transplant to the location of your choice.
