1-Purchase or find some frangipani seeds.
2-Plant seeds in groups in small posts in rich potting mix.
4-Protect from direct sun, heavy rain and animals.
5-Repot after 6-12 months into individual pots.
Each frangipani seed will produce a unique flower. Seedlings often grow for several years before flowering so waiting to see the flower type requires patience but can be exciting.
Seedlings grow for several years into a one metre thick single stem plant before forking.
