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]
Soaking bulbs is not necessary. Fall bulbs should be planted as soon as the ground is cool usually, when the evening temperatures are constant between 40 to 50 degrees.
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.
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 ...
O. umbellatum is a perennial herbaceous bulbous plant , dying back after flowering, to an underground storage bulb. The following year, it regrows from the often shallow rooted bulbs, which are ovoid with a membranous coat, [ 2 ] 15–25 millimetres ( 1 ⁄ 2 –1 inch) long and 18–32 mm ( 3 ⁄ 4 – 1 + 1 ⁄ 4 in) in diameter.
Flowering plant bulbs are planted beneath the surface of the earth. The bulbs need some exposure to cold temperatures for 12 to 14 weeks in order to bloom. [1] Flower bulbs are generally planted in the fall in colder climates. The bulbs go dormant in the winter but they continue to absorb water and nutrients from the soil and they develop roots ...

The bulbs are slender, conical, 2–3 cm (3 ⁄ 4 – 1 + 1 ⁄ 4 in) long and 1 cm (1 ⁄ 2 in) broad, and grow in dense clusters from the roots. The scapes (or stems) are hollow and tubular, up to 50 cm (20 in) long [ citation needed ] and 2–3 mm ( 1 ⁄ 16 – 1 ⁄ 8 in) across, with a soft texture, although, prior to the emergence of a ...
