Introduction to Floriculture
Floriculture is a vast field that includes cultivation and production of all types of ornamentals, viz., croton, cacti, orchids, grasses and bamboos. Besides cultivation, it includes layout and designing of gardens, study of various styles and features of garden and landscaping. The various field of revenue generation in floriculture includes cut flower production, loose flower production, nursery plants, potted plants, seed industry and extraction of essential oils. It has the potential for generating employment opportunities round the year and earning livelihood and valuable foreign exchange. India exports many floricultural products such as cut flowers, potted plants, etc., to many countries of the world. Export of floricultural items is important for our country’s economy. About 30 per cent of the economy of a small country, like Holland, is based on the export of cut flowers.
Floriculture is a branch of horticulture that deals with the cultivation, processing and marketing of ornamental plants, vis-a-vis landscaping and maintenance of gardens so that surroundings may appear aesthetically pleasant.

Floriculture in the Indian economy
According to the National Horticultural Board Database, (2016–17) the leading flowers producing States in the country are — Tamil Nadu (19%) followed by Karnataka (13%) and West Bengal (12%).
Maharashtra, Karnataka, Andhra Pradesh, Haryana, Tamil Nadu, Rajasthan, West Bengal have emerged as major floriculture centres (APEDA, 2016–17).
The share of floricultural products in total horticultural produce is 1.1% (NHB Database, 2015–16).
About 2184.0 (‘000 MT) flower production was estimated with the area of 278.0 (‘000 ha) (NHB Database, 2015–16).
Loose and cut flowers share in the total flower production is 1656.0 (‘000 MT) and 528.0 (‘000 MT), respectively (NHB Database, 2015–16).
The highest production of flowers was recorded in Tamil Nadu (416.63 thousand tonnes),followed by Karnataka (280.92 thousand tonnes) (NHB Database, 2015–16).
The annual growth trend of area and production of horticulture crops are 11.6% and 1.9%, respectively (NHB Database, 2016 –17).
At present, the share of the Indian floriculture products in the international market is about 0.6% (APEDA, 2015–16).
India’s total export is 22,000 metric tonnes of floriculture products with the worth of 548.74 crore in 2016–17. Major export destinations are the United States, Germany, the United Kingdom, the Netherlands and the United Arab Emirates (APEDA, 2016–17).
There are more than 300 flower export-oriented units in India and more than 50% of the floriculture units are based in Karnataka,
Andhra Pradesh and Tamil Nadu (APEDA).
As per the ITC Trade Map, International Trade Statistics, 2014, India stands 14th in the world in exporting floricultural products, while the Netherlands and Columbia rank first and second, respectively.
Importance of floriculture
Floriculture is one of the most potential components of the horticulture industry, being important from aesthetic, social and economic points of view. The importance of commercial floriculture are as follows:
(a) Production of cut flower
Cut flowers are harvested with stalk, especially for arrangement in vases. These are long-lasting and constitute a major share of the total world trade in floricultural products. Important cut flower crops are — rose, carnation, chrysanthemum, orchid, gerbera, lily, gladiolus, tulip, narcissus, bird of paradise, heliconia, anemone, ranunculus, tulip, calla lily, etc. Cut flowers are used in bouquet preparation or floral baskets, as corsages, in landscape gardening, flower arrangement and for decoration.
(b) Production of loose flower
Loose flowers are plucked from plants just below the calyx. These do not have attached stalks. Loose flowers are in great demand, especially in Asian countries for making veni, rangoli, bracelets, hair adornments for women and garlands, religious offerings and decorative purposes at various social functions. Loose flowers comprise rose, chrysanthemum, marigold, jasmine, tuberose, gaillardia, crossandra, barleria, chandni, kaner, hibiscus, spider lily, eranthemum, etc.
(c) Production of cut greens
Cut greens or cut foliage (leaves and stems) are attractive in form, colour and freshness. These are long-lasting and in great demand in floriculture trade. These are used as filler with cut flowers in flower arrangement, and elsewhere for increasing aesthetic value. They have various uses in fresh and dried floral designs and floral ornaments, such as bouquets, wreaths, interior decoration, etc. Some of the cut foliages in demand are asparagus, ferns, thuja, cupressus (goldcrest), eucalyptus, etc.
(d) Potted plants
These are of considerable commercial importance for instant gardening and for indoor, as well as, outdoor decoration. Potted plants can be carried wherever needed. These may be either of ornamental foliage or flowering. They are used for indoor decoration at homes, offices, commercial complexes, corporate offices, hotels, malls, and for decoration of sites during various functions or occasions. The importance of these plants is increasing because with the growing population and lack of open spaces, one has to largely depend on potted plants for decorating their surroundings. Examples of potted plants are — aglaonema, aralia, azalea, calathea, chlorophytum, croton, diffenbachia, dracaena, ferns, ficus, kalanchoe, maranta, money plant, senecio, syngonium, etc.
(e) Flower seeds and planting materials
There is a lot of demand for good quality flower seeds, especially annual ornamentals and ornamental planting materials. Availability of a great variety of soil and climatic conditions enables seed production of practically all types of flowers. Flower seeds of annuals are produced in large numbers for sale. A large number of bulbous plants, such as gladiolus, tuberose, amaryllis, dahlia, lilies, freesia, tulip, calla lily, etc., are multiplied and marketed.
Nurseries are meant for multiplying and supplying plants and planting materials. Ornamental plant nursery is a lucrative retail or wholesale business for supplying various types of plants and planting materials. Planting materials include nursery seedlings or prepared plants of trees, shrubs, climbers, annual seedlings, perennials, foliage plants, bulbous plants, cacti and other succulents, palms, plants for indoor decoration, grasses, seeds, bulbs, etc.
It is a well-mown turf made in the field, in front of a house, open space or in a garden. Lawn is made for various purposes and for providing clean air and elegant environment. A lawn is an integral part of garden, providing a beautiful environment for onlookers and emitting fresh oxygen to the environment as a lung does for the body. It has aesthetic and recreational value. It is believed that lawns improve the value of property by 15 to 20 per cent. It improves curb appeal. Various kinds of grass can be used according to the purpose of lawn use, like golf, hockey, badminton, tennis, etc.
(h) Production of perfumes
The demand for natural floral extracts, like perfumes, from flowers, is increasing by the day. Some flowers, such as rose, jasmine, screw pine and tuberose are used for the extraction of essential oils, which are a base for the preparation of perfumes, scents or attar. These flowers are produced for the extraction of high-grade floral perfumes.
(i) Dried flowers
Since fresh cut flowers and cut foliage are comparatively short-lived and have limited availability period, dry flower technique is used, wherein flowers can be easily dried, preserved and processed to retain its beauty, as well as, value for a longer period of time. The common examples of air-dried and mostly used as dry flowers include acroclinum, dahlias, larkspur, helichrysum, lotus pods, etc.
In floricultural exports from India, these products constitute 60–70 per cent.
(j) Extraction of colour pigments
Flowers are used to extract natural pigments. Carotenoids, extracted from flowers, are used commercially in pharmaceuticals, food supplements, and animal feed additives and as food colourant. In poultry industry, for intensifying the yellow colour of egg yolk, petals of marigold are used as a feed additive. It is also used to prevent diseases of the eye in humans. From chrysanthemum flower, a yellow-coloured dye is extracted for use in food products and cosmetics.
The arils of Achiote (Bixa orellana) is used in cosmetics and medicines for coating having orange red colour dye.
(k) Pollution-free environment
The role of open spaces like parks and plants in checking air pollution is a well-known fact. Parks are considered as the lungs of cities. Ornamental plants help improve the environment aesthetically and health-wise. Some trees have been found to be useful in preventing air and noise pollution in urban areas. Trees provide shade and create better microclimate. Parks or gardens also serve as recreation spots and are known to have positive effect on physical and mental health apart from providing a peaceful atmosphere for meditation.
Aesthetic value of flowers
‘Aesthetic’ is the perception of beauty and study of its appreciation. Aesthetic value may be defined as the theory of the level of beauty of certain natural resources. It is the value or pleasure that anything beautiful gives to humans. Flowers symbolise passion, purity, beauty, innocence, peace, love, adoration, etc., and are well-proofed for their aesthetic value. Some common aesthetic values of flowers are as follow:
Flowers bring feelings of peace and comfort when given to an ailing member at home or in hospital or rehabilitation centres, and to family members or
friends in general. They help in achieving higher level
of personal development and satisfaction.
Landscaping is the treatment of waste or otherwise free land with a goal to make it attractive and beautiful. Landscaping is becoming common as it improves the environment of an area, brings in calmness, freshness and increases aesthetic value. This is important for offices, residences, supermarkets, etc., as the first look of a building’s exterior is expected to give a pleasant overall appearance. Parks and gardens provide an opportunity for a large number of people to relax and enjoy the beauty of nature. A lawn is an integral part of a garden and is primarily for aesthetic purpose.
(c) Indoor gardening
Growing plants inside a house is known as indoor gardening. It not only makes the appearance of indoors beautiful, pleasant and attractive but also improves the air quality and adds freshness to an area.
(d) Flower arrangement
Flower arrangement is the aesthetic and artistic form of flower display, which refreshes the mind. It provides a means of livelihood to the arranger. Cut and loose flowers are used for various flower arrangements and can be presented on various occasions, such as weddings, birthdays, etc. They add beauty to the table when used as a centrepiece.
Prospects and present status of floriculture in India
Due to the changing lifestyles and increase in the per capita income, the demand for floriculture has also gone up substantially. At present, it has become one of the profit making trades, owing to constant rise in the demand of flowers and its products.
Floriculture exports from India are primarily dominated by fresh cut flowers and dried flowers.
The various fields of revenue generation in floriculture include cut flower production, loose flower production, nursery, potted plants, seed industry, extraction of essential oils and value-added products.
The production of loose flowers is the highest in Tamil Nadu, followed by Karnataka and Madhya Pradesh, whereas, the production of cut flowers is the highest in West Bengal, followed by Karnataka, Odisha and Uttar Pradesh.
Several seed companies have established production units in major flower growing states to meet the demand of flower seeds.
Seasonal flower seed production is a established business in Punjab, Karnataka and Maharashtra.
Some of the agri-export zones for floriculture set up by the Government of India are in Maharashtra, Sikkim, Tamil Nadu, Uttarakhand and Karnataka (APEDA).
In terms of floricultural production and export units, south India dominates, having more than half of the total units.
The United States, Germany, the United Kingdom, the Netherlands and the United Arab Emirates are perhaps some of the major countries, which import floricultural produce from India.
Prospects of Indian floriculture
Since time immemorial, India has a tradition of growing flowers. It is considered as a high growth industry. The export-oriented flower production has increased due to the government’s liberal policies.
The scope of floriculture in India are as follows:
Opportunities for floriculture are increasing due to various uses of flowers — for aesthetics, prayers, festivals and other occasions, and perhaps due to the increasing purchasing power of people.
The demand for floricultural plants and their produce, such as bouquet, garland, veni and value-added products, like dry flowers,pot-pourie, is increasing day-by-day in various functions and celebrations.
Strategically and geographically, our country is well located between major flower markets— Europe and East Asia.
Export is likely to get a boost due to the development of model floricultural centres and agri-export zones created by the government.
The availability of diverse agro-climatic conditions in the country enables to grow all flowers in one season or the other.
The winter season is mild in India as compared to other flower producing temperate countries. This provides us with an opportunity to grow and produce flowers and seeds for export during the season when the demand is high because of Christmas, New Year, Easter, Mother’s Day, Father’s Day and Valentine’s Day.
Floriculture offers employment for skilled, as well as, unskilled human resources, including rural youth and women.
Landscaping has become an integral component of urban horticulture, which apart from its aesthetic value, protects the environment, reduces air and noise pollution and promotes eco-tourism.
Lawn establishment and maintenance have become an integral part of landscaping, which require skilled, as well as, unskilled human resources. This has become a lucrative enterprise.
In the light of climate change, the scope of turf or lawn grasses, vertical gardening, roof gardening, etc., is on the rise.
Increasing industrialisation and depleting agricultural land has opened avenues for the production and marketing of potted plants. It has also opened avenues for plant rentals for interior decoration in hotels, corporate houses, etc.
Nursery industry is coming up as a flourishing enterprise, giving high returns. There is ademand for high quality flower seeds, including F1 hybrids.
Protected and hi-tech cultivation of cut flowers has a great future. One can increase the area under intensive flower production to increase floricultural exports.
The extraction of essential oils, natural dyes, pharmaceuticals and nutraceutical compounds from flower plants is also an important activity and is coming up as a lucrative business.
Classification of ornamental plants
Based on life span
Plants, which complete their life cycle from seed germination to seed production in one growing season, are ‘annuals’. They complete the process of life, such as seed germination, growth, flowering, seed formation and die in one growing season or year. They require replanting in every season. They are mostly grown through seeds and are commonly called ‘seasonal’. Examples are China aster, coreopsis, gomphrena, marigold, petunia, tithonia, verbena, zinnia, etc.
These are the plants that complete their seed-to- seed life cycle in two seasons or two years. Usually, most of the temperate season plants are biennial in nature as they complete vegetative growth in one season or year and flowering to seed formation in another season or year, such as amaranthus, celosia, hollyhock, pansy, snapdragon, etc. These require replanting.
Plants that have a life cycle that is more than two years are called ‘perennials’. They produce seeds or flowers every year once the bearing starts. They do not require replanting. Once planted, they flower every year. Perennials are, usually, categorised into two groups.
These mostly comprise trees, shrubs and vines, which have woody stems and branches, such as Cassia siamea, C. fistula, Peltophorum, Cassia biflora, Lawsonia alba, Hibiscus rosa-sinensis, Petrea volubilis, Quisquallis indica, Vernonia eleagniaefolia, etc.
These comprise plants with soft and herbaceous
(non-woody) main stalk, such as anthurium, bird of paradise, geranium, gerbera, heliconia, pelargonium, periwinkle, portulaca, perennial balsam, sweet violet, viola, etc.
Based on season of growth
Winter season annuals
Winter season annuals are hard to grow during the rigours of winter, withstanding low temperature. The seeds of annuals are sown in September–October and the seedlings are transplanted in October–November, for example, candytuft, antirrhinum, larkspur, nasturtium, pansy, petunia, phlox, sweetsultan, verbena, etc.
Summer season annuals
These are grown in the summer season and can tolerate high temperature to produce flowers. The seeds are sown in the end of February or beginning of March and seedlings are transplanted in the end of March–April, for example, cosmos, gaillardia, gomphrena, kochia, portulaca, sunflower, tithonia, zinnia, etc.
Rainy season annuals
Rainy season annuals are grown during the rainy season and can produce flowers under high humidity and rainfall as compared to other annuals. Seeds are sown in June and seedlings are transplanted in July. The example are amaranthus, balsam, celosia, cock’s comb, gaillardia, etc.
Based on market value
Loose flowers are harvested without stalk. Examples of loose flowers are — barleria, bedding dahlia, calotropis, chrysanthemum (spray type), chandni, crossandra, eranthemum, gaillardia, jasmine, kamini, kaner (yellow and red), lotus, marigold, rose (fragrant desi type), shoe flower (hibiscus), sunflower, tuberose, water lily, etc. They are used for making rangoli, gajra, veni, garland, and offered for worships at home, as well as, in religious places.
Cut flowers are fresh flowers, flower buds or spikes harvested along with their stems attached to the flowers, length of stems being as specified to individual flowers. Examples of cut flowers are alpinia, anthurium, antirrhinum, bird of paradise, carnation, freesia, gerbera, gladiolus, gypsophila, heliconia, iris (bulbous), lupins, narcissi, orchid, rose (improved varieties), scabiosa, statice, tuberose, watsonia, etc. They are mostly used for bouquets and vase arrangements.
Flower yielding value added product
They are used as raw material in industries for the extraction of essential oils and preparation of edible products, such as gulkand and rose water. They are also used for the extraction of pigments as natural colours, and as dry flowers, such as acroclinum, jasmine, marigold, rose, etc.
Based on type of plant
Lilium, verbena, viola, etc.
Bougainvillea, jasmine, lawsonia, hamelia, nyctanthes, rose, tecoma, etc.
Gulmohar, palash, amaltas, kadamb, pride of India, etc.
Climbers and Creepers
Adenocalymma, Antigonon, Rangoon creeper, madhulata, petrea, thunbergia, etc.
Based on mode of propagation
Lily, narcissus, tuberose, tulip, etc.
Crocus, gladiolus, tritonia, watsonia, etc.
Canna, hedychium, iris, lotus, etc.
Begonia, dahlia (root tuber), etc.
