Small bulbs can develop or propagate a large bulb. If one or several moderate-sized bulbs form to replace the original bulb, they are called renewal bulbs. [7] Increase bulbs are small bulbs that develop either on each of the leaves inside a bulb, or else on the end of small underground stems connected to the original bulb. [7]
The bulbs are produced to satisfy the demand for bulbs for parks, gardens and as house plants, in addition to providing the bulbs necessary for the production of cut flowers. The international trade in cut flowers has a worldwide value of approximately 11,000 million Euros, which gives an idea of the economic importance of this activity.

In some flowers, a tube or cup-like hypanthium (floral tube) is formed above or around the ovary and bears the sepals, petals, and stamens. There may also be a nectary producing nectar. Nectaries may develop on or in the perianth, receptacle, androecium (stamens), or gynoecium. In some flowers nectar may be produced on nectariferous disks.
Diagram of flower parts. In botany, floral morphology is the study of the diversity of forms and structures presented by the flower, which, by definition, is a branch of limited growth that bears the modified leaves responsible for reproduction and protection of the gametes, called floral pieces.
The flower is pollinated by bumblebees and other bees. The bulbs are an important and preferred food of the grizzly bear. Mule deer readily eat the foliage. [11] [12] [13]After hummingbirds migrate 1,500 miles each year from Mexico to the Rocky Mountains of Colorado they collect energy from the nectar of the lilies, however, rising temperatures from global warming cause the flowers to bloom ...
The bulbs begin to grow as soon as they are planted, with flowers appearing in 3–4 weeks. Narcissus papyraceus thrives in moist, peat moss based potting mix. Plants can also be grown in containers of water. Cool temperatures between 50–65 °F (10–18 °C) and indirect light will help to prolong the bloom time. [4] [5]
Floriculture crops include cut flowers [1] and cut cultivated greens, bedding plants (garden flowers or annuals, and perennials, houseplants (foliage plants and flowering potted plants). [2] [3] These plants are produced in ground beds, flower fields or in containers in a greenhouse. Protected cultivation is often used because these plants have ...
