The hibiscus is a perennial known for its large, showy flowers that come in a wide range of colors and shapes. The foliage is also striking, with large, glossy leaves on tall, slender stems. The plant is grown primarily in warmer climates (USDA hardiness zones 8 to 10). Hibiscus seeds can be purchased or collected from the pods of parent plants.
Cut disposable cups to about 3 inches high. Punch holes in the bottom for drainage and fill each cup with fine potting soil.
Nick the tip of each seed with a sharp knife to allow the seed to absorb water more easily, improving the chance of germination.
Check the nick to make sure the seed is viable. Look for the white endosperm in each seed.
Make a hole in the soil about 1 inch deep and put one seed in each cup.
Cover the seed with potting soil and water it lightly. Place each cup in a medium-size resealable plastic bag to keep the seed moist.
Place the containers in the sun. Watch for growth in two to three weeks. Spray the soil with water to keep it damp but not wet.
Remove the plastic bags after the seeds have sprouted. Continue to water regularly.
Transplant your seedlings once they have grown to several inches. Plant them in larger pots or fertile, prepared soil in your garden.
