Hibiscus flowers, also known as wood hibiscus, frost repellent flowers, wood lotus, ground hibiscus, hua wood. It is a deciduous shrub or small tree, 2-5 meters tall.
Hibiscus flower twigs, petioles, peduncles and calyxes are densely covered with fine cotton hairs mixed with stellate hairs and straight hairs.
Hibiscus leaves are broadly ovate to round-ovate or heart-shaped, 10–15 cm in diameter, often 5–7 lobes, lobed triangular, tapering at the apex, blunt circular serrations, sparsely covered with stellate fine hairs and dots above, densely covered with star-like fine villi below; 7–11 main veins; petiole 5–20 cm long; lanceolate, 5–8 mm long, often falling early.
Hibiscus flowers are singly born between the axillary of the branches and leaves, the peduncle is about 5–8 cm long, with segments at the proximal end; the small bracts 8, linear, 10–16 mm long and about 2 mm wide, densely covered with stellate woolly hairs, basal synophysis; calyx bell-shaped, 2.5–3 cm long, lobes 5, ovate, tapering; white or reddish at the beginning of the flower, later dark red, about 8 cm in diameter, petals nearly round, 4–5 cm in diameter, hairy on the outside, hairy at the base; stamens 2.5–3 cm long, hairless; peduncule branches 5, sparsely hairy.
Hibiscus flowers are flattened and spherical, about 2.5 cm in diameter, covered with pale yellow bristles and woolly hairs, the seeds are kidney-shaped, and the back is covered with long soft hairs.
Hibiscus flowers like light, slightly shade-tolerant; prefer warm and humid climate, not hardy, when planted in the open field north of the Yangtze River Basin, the aboveground parts often freeze to death in winter, but in the spring of the second year, new strips can germinate from the roots, and autumn can bloom normally. Prefers fertile, moist and well-drained sandy loam soils. It grows faster and is more tillery.
The propagation of hibiscus flowers includes cuttings, pressed strips, and plant divisions.
The most appropriate time for hibiscus cuttings is in late autumn and early winter, waiting for the leaves of the wood hibiscus to fall. It is best to choose the stout branches of the year, cut them all at 5-10 cm from the ground, cut them into 10-15 cm cuttings, trap them into bundles and put them in a leeward and sunny place to dig a ditch for overwintering, and cover them with clean wet sand to keep them moist. In February and March of the following year, the cuttings are removed, unbundled, and inserted into the seedbed one by one, and the exposed parts should not exceed 10 cm, and then covered with some grass, the survival rate is very high.
Hibiscus flower strip time in June-July, the branches of the wood hibiscus are bent, careful not to break, and then pressed into the soil, after a month you can take root, and in another month you can break off from the mother plant. Dig out the sub-plants, bury them in a greenhouse or cellar for wintering, and plant them the following spring.
It is best done in early spring before the plant germinates. Prepare the soil with sufficient base fertilizer in advance, dig out all the old plants, divide them into several plants according to the trend of their roots, and then immediately plant them into the prepared soil, preferably after a week of watering, if they grow well, they can bloom that year.
Hibiscus flower seeds are propagated in January-December to pick ripe fruits, dry storage, sowing in the following spring, burying the seeds deep in the dug ditch, covering with soil, and covering them with grass, and seedlings can be produced in about half a month, and some can also flower that year. In addition, the cilia on the seeds of the wood hibiscus can fall with the wind and can be multiplied on the ground.
Hibiscus flowers are fertilized by punching holes, that is, evenly punching holes near the canopy. Before flowering, urea plus appropriate phosphate fertilizer is applied at the beginning of flowering, about 0.5kg per plant, sprinkled on the root of the canopy, and then watered, which can make the flower color more colorful.
Hibiscus flowers need to meet their water needs during the spring budding period, especially during the dry season in the north, and need to be frequently watered. In the hot summer season, more water should be used to keep it moist, and places with difficult water sources can be covered with straw, and the moisturizing effect is good. With the decrease of the temperature, the appropriate amount of water after autumn is reduced, and the water should be properly controlled when the buds are transparent, so as to control the growth of their leaves and concentrate nutrients on the flowers. Open-field cultivation of hibiscus flowers is extensively managed, because the natural precipitation law is roughly consistent with its growth water needs, except for the summer season, other times can basically meet its water needs.
The use of potted hibiscus flowers should be selected larger porcelain pots or vegetarian pots, the potting soil requires loose and fertile, good drainage and breathability, and sufficient moisture during the growing season. Moving to the leeward sun in winter ensures that it is fully dormant.
Hibiscus flowers are cold-tolerant and prefer sunshine, and cold areas should be planted in the sunny place of the wind, and excessive shade grows slowly, and the branches are slender, affecting the differentiation of flower buds. In the middle of summer, it is better to shade it slightly. Autumn pregnant bud flowering period needs sufficient light, so when the light is insufficient, coupled with continuous rain, it is easy to cause falling buds.
Hibiscus flowers are picked from August to October for the first bloom and are dried or dried. Flowers and leaves can be used in medicine. Take the original herbs, remove impurities, spray with water, moisten slightly, chop and dry. Tablet traits: irregular filamentous or fragmented, hairy, dark yellow-green on the upper surface, gray-green on the lower surface. The smell is slight, the taste is slightly spicy. Store in a drying container and place in a ventilated and dry place.
Hibiscus flower stem skin contains 39% cellulose, stem skin fiber flexible and water-resistant, white and flexible, water-resistant moisture, can be used for textile, rope, cable, as a hemp substitute and raw materials, but also for papermaking and other uses. The ancients also used hibiscus flowers to mash juice and dye silk as an account, that is, the famous "hibiscus tent".
Hibiscus flowers prefer warm, moist environment, not hardy, avoid drought, water and moisture. The soil requirements are not high, and the barren land can also grow. It is a deciduous shrub or small tree of the family Mallowaceae, Hibiscus genus. The flowers are solitary between the axillary of the branches and leaves. Its flower language is delicate beauty, chastity, purity.
Hibiscus flowers in China's Liaoning, Hebei, Anhui, Jiangsu, Zhejiang, Jiangxi, Guangdong, Guangxi, Hubei, Sichuan, Guizhou and Yunnan provinces and regions cultivated, after long-term cultivation, wood hibiscus has formed different varieties, common are: white flower wood hibiscus, white flowers; drunken hibiscus, heavy petals, flowers at the beginning of the flower is pure white, and then becomes dark red, for rare and valuable varieties.
