Flowers are a symbol of good and happy human life. With the development of society and the increasing abundance of material life, people's demand for flowers is increasing. It has become a fashion to decorate and beautify life with flowers. There are many kinds of flowers and they are widely distributed. They are both terrestrial and aquatic. They are small and some are tall and upright. There are flowers, foliage, and stems. There are also herbs and woody trees. . Different forms, ecological habits vary greatly. To understand and use them, we must scientifically and systematically classify them. According to the classification of natural families, they are classified according to their characteristics, habits, origin, cultivation methods, and garden applications.
First, classified according to ecological habits
A certain plant lives in a certain environment for a long time and is affected by the specific environmental conditions, forming the inherent law of its growth and development, that is, ecological habits. Classified according to the ecological habits of flowers, the application is very extensive.
(a) open flowers
Under natural conditions, the flowers that can complete all the growth process without the need for protection facilities are usually referred to as grass flowers. If you need to flower in advance, you can use a cold bed or a hotbed to raise seedlings in early spring. Open flowers can be divided into three categories according to their life history:
[Annual flower], also known as spring sowing flower, refers to a flower that can complete the life history in a growing season. That is, the life cycle from seed to seed is completed within one year. It is usually planted in the spring and it blooms in the summer and then it dies. Such as impatiens, celosia, cosmos, zinnia, half-branch, straw chrysanthemum, marigold and so on.
The "two-year-old flower", also known as the autumn sowing flower, refers to the flower that completes the life history in two growing seasons. In the first year, it only undergoes vegetative growth, and flowering, fruiting, and withered in the following year. Generally sowing in the fall, the spring and summer flowers the following year. Such as dianthus, violet, bamboo incense, kale and so on.
Perennial flowers have an individual life of more than two years and can be flowered many times. Because of the morphological changes in the underground part, they are divided into two categories: perennial flower: The underground part of the plant remains winter and does not inflate. Such as valerian, peony, jade peony, peony, peony, hollyhock and so on.
Flower bulbs: perennial metamorphic hypertrophy, globular or lumpy perennial herbaceous flowers. Such as Gladiolus, lily, tulip, narcissus, calla lily, canna, dahlia and so on.
The open field herbaceous flower species (variety) are numerous, colorful and colorful, flowering is luxuriant, the flowering period is concentrated, easy to flower, the beautifying effect is fast, and the decoration is strong, and it is suitable for large area applications.
(b) Greenhouse flowers
Local ornamental plants that are cultivated in the greenhouse all year round or for a long period of time. Its species varies from region to region, such as hibiscus, mimosa, jasmine, and camellia. They are exposed flowers in South China, while in northern China they are greenhouse flowers. The potted flowers such as gerbera, carnation, anthurium and primrose, which are cultivated in the greenhouse, are also commonly used as greenhouse flowers.
One-year-old greenhouse flowers such as cineraria, calendula, sweet peas, etc.
[Greenhouse perennial flowers] such as evergreen, gerbera, and clivia.
ã€Greenhouse Bulb Flowers】 such as Cyclamen, Hippeastrum, Gloxinia, Calla Lily, etc.
According to their different ecological habits, orchids can be divided into different types of orchids, such as Chunlan, Cymbidium, Jianlan, Molan, etc.; Epiphytic orchids, such as Dendrobium, Carteran, and Phalaenopsis.
Cactus and Polyplasma Plants The stems and leaves have a well-developed water-retaining structure and are hypertrophic and hyperplastic. Including cacti, Apricotaceae, Sedum, Euphorbiaceae, Asteraceae, Bromeliaceae, Agaveaceae and other families.
[Pteridophytes] such as Adiantum fern, Valerian and so on.
Palm Plants such as Livistona, palm, palm, Drosophila, and mackerel.
Second, according to the use of garden classification
ã€Flower Altar Flower】 The plant material applied in the flower bed is mainly a biennial herbaceous flower, a perennial flower, a bulbous flower, and a small amount of woody flowers.
Potted Flowers: Multiple-fingered plants are smaller, closely planted and planted in pots, while flowers with higher ornamental value are used.
[Indoor flower] refers to an ornamental plant that can be planted indoors for a longer period of time to adapt to indoor conditions. It is mainly produced in tropical and subtropical areas, with foliage, flower, and fruit, and is the main material for a variety of indoor green decoration.
ã€Flowers cut flowers】 have ornamental value, and can cut stems, leaves, flowers, fruits and other flowers as decorative materials.
ã€Arboreal Flowers】 Flowers that need to be cultivated and propagated in shade sheds are called arboreous flowers. It includes both shade flowers and flowers that are grown in the country of origin, but cannot stand the strong sunshine or dry heat environment in which they are cultivated, and thus they need to be protected under the shed to grow in health.
