Flower types: spring flowers (March-May), summer flowers (June-August), autumn flowers (September-November) and winter flowers (December-February). Commonly used woody flowers are plum blossom, peach, peony, begonia, magnolia, wooden pen, bauhinia, forsythia, Admiralty, clove, wisteria, cuckoo, pomegranate, smiling flower, etc. Tulip, violet, snapdragon, Changchun Chrysanthemum, Guayeju, sweet pea Xia Lan, Dianthus chinensis, Lycoris radiata, lotus, Cuiju, water lily, Paeonia lactiflora, Fluke, tuberose, marigold, Cymbidium hybridum, tuberose, Cymbidium lily, Ciruhua, Corydalis saxicola, Narcissus, Eupatorium adenophorum, Guaye. In South China, most of them are annual flowers, and biennial flowers are not easy to bloom on the flat land. Annual grass flowers have a short cultivation period, usually bloom within 2-6 months, and will naturally die after flowering and fruiting, such as pansy, zinnia, cockscomb, bunch of red flowers, malachite, cosmos, calendula and so on. Annual grass flowers are all positive plants, and the cultivation site must have enough sunshine to grow and bloom normally. If the sunshine is insufficient, it will easily lead to poor growth and long growth, but it is not easy to bloom. Although the life span of grass flowers in a year is short, the flowers are bright and beautiful, which can be used as potted plants, cut flowers or flower beds for beautification. In landscape application, the species can be changed alternately according to the seasons, bringing people fresh, gorgeous and spectacular visual enjoyment. Perennial grass flowers, also known as perennial grass flowers, generally refer to perennial grass flowers with beautiful flowers and mainly ornamental flowers among perennial herbs. The life span of perennial grass flowers can last for many years. No matter whether the aboveground part has blossomed or not, the underground part still keeps alive, and it can sprout and grow again in the next year, such as African impatiens, chrysanthemums, gerbera, ornamental pineapples, Belamcanda, African violets, birds of paradise, firecrackers and so on. Perennial grass flowers can be used for ornamental purposes, such as garden flower beds, potted plants, cut flowers and flower arrangement materials. Especially in flower arrangement materials, perennial grass flowers are the main source of flower materials, such as chrysanthemum, carnation, candle, gypsophila, bird of paradise and star flower. Perennial grass flowers have positive plants that like adequate light, and negative plants that like to grow in loose and soft light. Seasonal temperature changes and the length of sunshine have obvious effects on the growth and flowering of perennial grass flowers, which must be managed properly to bloom smoothly. Perennial grass flowers are mainly ornamental flowers, which can be potted, decorated with gardens and used as flowers, which is of great help and contribution to the greening and beautification of home environment and people&;s physical and mental adjustment. . Vines, also known as vines or vines, refer to those whose stems and branches are easy to elongate and cannot be independent, and can only grow normally by winding and climbing their tendrils or vines, even crawling on the ground, including herbaceous vines and woody vines, which are divided into climbing vines, such as melons, Ficus pumila and Parthenocissus humilis.Whiskers or indefinite air roots can entangle other things to grow. Twisted vines, such as morning glory, rose fish, yellow grass, black eel vine, honeysuckle, etc., can grow around other things. Creeping vines, such as Marsdenia tenacissima, Huang Jinju, etc., have stems and vines that can grow on the ground, and roots are easily generated where they touch the ground. Vine shrubs, such as bougainvillea, jasmine, Yunnan jasminum giraldii, Guangyao rattan, etc., are originally shrubs, but their branches are semi-vine or vine-like after elongation, and they can grow independently or depend on other things. In landscape, vine plants can be used in flower corridors, flower stands, hedge walls, shaded sheds for beautification or potted plants, etc. Their stems and vines can bloom for viewing after climbing the shed, and a cool space can be formed under the shed for rest, which has a special purpose. Among perennial herbaceous flowers, bulbous flowers are called &”;bulbous flowers&”; because their rhizomes are particularly hypertrophy, and they are blocky or spherical, and they can store nutrients for germination and flowering. According to the different shapes and parts of hypertrophy, it can be divided into bulbs (such as Lily, Zhu Ding Opera, Narcissus, tennis flowers), corms (such as gladiolus, crocus, freesia), tubers (such as Erythrina macrophylla, colorful taro, long tube flowers), tubers (such as Dahlia, Jialan), rhizomes (such as Canna, hedychium coccineum) and so on. Bulb flowers can be divided into temperate or tropical varieties according to the same origin. Temperate varieties like to be cool (such as tulip, hyacinthus orientalis, narcissus, etc.). It is not easy to cultivate flowering bulbs in South China, and bulbs are imported from other places every year and bloom after short-term cultivation. Tropical varieties (such as tuberose, tennis flower and canna) grow well in South China all year round. The growth cycle of bulbous flowers has a common long-t—— dormancy. The dormancy period varies from variety to variety, about 30-90 days. During dormancy, the stems and leaves wither and die, and a large amount of nutrients are stored in underground bulbs. However, some varieties only stop growing during dormancy, and there is no obvious phenomenon of death (such as Zhu Dinghong, Eupatorium adenophorum and Echinacea, etc.). In cultivation, in order to shorten the dormancy period and promote orderly flowering, low-temperature refrigeration is often used to break the dormancy of bulbs. Reference: www1.flowerchina.net.
