Plumeria is a tropical flowering tree. The delicate flowers are also known as frangipani and come in colors ranging from white and pink to yellow and red. While plumeria is usually grown from cuttings, it can also be started from seeds. Seeds are not normally sold but you can collect them from your own plumeria trees or from those of a friend or neighbor if you wish to grow this attractive and fragrant deciduous tree in your landscape.
Fill a seed-starting tray with 2 inches of moist potting soil. Use a quality potting mix that is sold sterilized to limit the chances of soil-borne disease.
Sow the seeds just beneath the soil surface. Space them 3 to 4 inches apart in all directions.
Place the pot in a warm room to germinate. Water the soil as necessary to keep it moist but not soggy. Plumeria germinates within two weeks on average.
Move the seedling tray to a warm sunny and window. Continue to water as needed to maintain soil moisture.
Transplant the seedlings to individual 4- to 6-inch pots when they grow their second set of leaves. Lift the seedlings from the tray by grasping the topmost leaves in your fingers. Plant them in their new pots at the same depth they were at in the tray.
