In Europe the thick roots are used to harvest mucilage, which is used to make white marshmallow candy (9). The plants die to the ground in winter, and resprout in late spring. The plant grows 3 to 8 feet in height, and blooms from summer to the first frost. This variety grows well in wet, swampy areas, and is commonly found in marshes in the eastern United States, as well as southern states. Marshmallow hibiscus’ grow bold white, pink, red and fuchsia flowers. The plant grows quickly, and the expected lifespan is 5 years (8). The plant flowers from midsummer to early fall. Cinnamon Grappa grow up to 4 feet in height and 24 inches in width. The health of the soil and care of the plant correlate to color vibrancy, so it is important to maximize the health of hibiscus, as they can be sensitive plants (3).Ĭinnamon Grappa hibiscus are short and full, with deep-red showy flowers and glossy green leaves. Similarly, anthocyanins yield purple, blue, pink red and black pigments, while flavonols yield pale yellow and white flowers. Carotenoids yield yellow, red and orange pigments. Carotenoids levels increase in hot weather, which intensifies the vibrancy of flower color. Carotenoids are found in other orange colored foods such as carrots, squash and pumpkin. The same carotenoids and flavonoids that affect the pigment of hibiscus flowers are sources of vitamins. Many varieties of hibiscus actually change flower color due to possible variables such as temperature change and amount of sunlight received. Flowers grow up to 6 inches in diameter, with colors ranging from yellow to peach to red. Flowers are large, vibrantly colored, and grow over a long season. Plants in warm areas can grow up to 15 feet tall. Shrubs are deciduous and grow dark green leaves. Pruning is best done in winter when the plant is dormant. Pruning is recommended, and results in a bushier, fuller plant. Although hardy hibiscus can survive freezing temperatures, they grow best in warm weather, as cold weather can stunt bud growth (1). Tropical hibiscus requires steady temperatures, with ideal temperatures being between 65 and 75 F. Hardy hibiscus can survive the winter, while tropical hibiscus require warmer temperatures and to be transplanted during the winter. Hibiscus plants are members of the Mallow family and are either hardy or tropical. During the winter, hibiscus growth goes dormant, and should only be watered when soil is dry. Although hibiscus requires moist soil, over watering leads to fungal disease. Hibiscus thrive in full sun, and indoor plants should be placed in front of sun-facing windows. Hibiscus also thrives in soil that is rich in potassium and low in phosphorus. Acidity can be increased by adding potting mix or sphagnum peat moss into soil. The plant prefers acidic, moist, well-drained soil. Hibiscus is a tropical shrub or tree with vibrant trumpet-shaped flowers.
