China rose is just another name for Chinese hibiscus (Hibiscus rosa-sinensis), a botanical name which translates literally as rose of China. A tropical plant which grows in U.S. Department of Agriculture plant hardiness zones 9 through 11, China rose can be treated as an annual in cooler climates. It’s best known for its big, vibrant flowers.
China rose hibiscus is a perennial tree tree and can develop anywhere from 4 to 15 feet tall and 5 to 10 feet wide, though it may take several years for a shrub to reach maximum size. When treated as an annual, the plant will remain much smaller. Hibiscus can be implanted separately as a specimen or in rows to form hedges. China rose may also be trained as a standard, or little tree form, by removing all but one vertical stem and trimming the lower leaves as the plant grows. The plant will grow and bloom best in full sunlight, with at least six hours of direct sunlight each day.
The 4- to 6-inch diameter tropical blooms are the main attraction of China rose plants, and are favorites for hummingbirds and butterflies. The flowers can cover the whole plant once it gets enough sunlight and tons of water. Each flower only lasts for a day or 2, but the plant continually creates flowers. China rose’s standard blooms are generally medium to dark red. Dozens of cultivars widen the range of color choices, including purple, orange, yellow and white. Flower shape varies slightly among cultivars, but they generally feature five round-tipped petals around a dark-colored center. The petals are slender and slightly crinkly, often resembling wrinkled tissue paper. Some cultivars like “High Definition” and “Silver Medal,” both grown in USDA zones 9 through 11, have big, double blooms.
While certainly no competition for China rose’s dynamic blooms, the shiny green leaves are attractive even when the plant isn’t in bloom. The leaves are generally rounded or heart-shaped having a slight point in the tip. The advantages of the leaves might be serrated or scalloped, depending on the cultivar. Without pruning, branches tend to grow vertically without much secondary branching. If the tips are pinched back in spring and midsummer, you can attain a full, rounded bush. After the crops mature and are educated to the desired shape, continue trimming the tips at spring and midsummer. Remove about one-third of the older wood on adult China roses each spring to replenish the plant and stimulate new development. Sterilize pruning tool blades by wiping them away with alcohol prior to trimming. This prevents diseases being passed to healthy crops through infected blades. If you visit aphids, mealybugs or spider mites about the plant, then spray them off with a strong flow of water from your hose.
China rose plants may create beautiful blooms throughout summer when given proper care. The flower buds develop on new growth, so pruning of the advice in spring and midsummer ensures ample flowers during the season. Unlike many flowering plants, deadheading isn’t necessary for ongoing blossom production since the previous blooms fall off the plant on their own. Flower production might decline in times of drought, therefore water that the hibiscus frequently to maintain the soil fairly moist but not soaking wet. If the soil or plant remain too wet, China climbed might have issues with respiratory diseases. Proper watering can generally prevent these issues. It is possible to increase plant growth and flower production using a monthly application of a general-purpose fertilizer during the growing season from April to September. When using a frequent all-purpose, water-soluble fertilizer, like 24-8-16, by way of example, dissolve 1 tbsp of granules in 1 gallon of water. Apply the fertilizer to the ground around the plant as part of the normal watering schedule, utilizing 1/2 gallon for smaller plants and a full gallon for bigger plants.
