Most bulbs need to go through a cold period otherwise they probably won’t flower. You can plant them, and the leaves will grow. They will absorb sunlight and store it for the next year.
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.
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 ...
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.
Tigridia / t aɪ ˈ ɡ r ɪ d i ə /, [2] is a genus of bulbous or cormous flowering plants belonging to the family Iridaceae.With common names including peacock flowers, [3] tiger-flowers or shell flowers, they have large showy flowers; and one species, Tigridia pavonia, is often cultivated for this.
The bulbs of Nerine species need a minimum of two years growth and development in order to produce their first flowers. The largest bulbs can give rise to two stems or more if they have been grown under suitable conditions. They are used as cut flowers as they can survive up to 14 days in a vase with water without showing any staining. [12]
Bulbils on Agave vilmoriniana Paleoallium billgenseli bulbil with flowers. Within Agavoideae, bulbils develop on the inflorescence of a blooming plant. [3] [2] [4] The development of bulbils in this group is common in approximately 17 Agave species, all Furcraea species, and has been somewhat documented in Yucca (particularly Yucca elata), and Hesperaloe.
