Are you looking for some information inside the flowers? Here is a report to date of the flowers of experts who should know.
Bulbs are are among the most interesting, most beautiful and easiest to grow of all flower varieties. Tulip bulbs were so prized in Holland, which led one of the best known financial bubbles in history, and even today, tulips are a leading export from that part of the world.
Although the Light bulbs are so prized today as they were in 17th century Holland, they are still loved for their scents, their colors and shapes, and gardeners love the fact that most bulbs are hardy and easy to grow.
Many of the most popular varieties of flowers are actually grown from bulbs, including tulips, crocuses, daffodils, iris, lily, lilies, dahlias and snowdrops.
One thing all bulb based plants have in common is that they grow from structures located below ground. These underground structures provide the nutrients and energy that plants need to grow.
Even though bulb based plants collectively known as bulbs, in fact there are five different types of bulb plants true bulb, the corm, the tuber, the rhizome and the tuberous root. This article provide examples of each type.
The True Bulb
The true bulb is actually a underground stem base containing an embryonic plant. The embryonic plant contained in the steam base already contains the leaves, stems and flower buds are provided all ready to go off once the optimum growth conditions. This configuration allows the plant to remain dormant during adverse conditions, and thus to survive droughts and other environmental challenges.
If the flowers are out-of-date, how will this affect their actions and decisions? Be sure not to leave flowers important information slip by you.
The embryonic plant contained in the stem base is surrounded by scales (modified leaves that overlap in a manner reminiscent of reptile or fish scales). In the bottom the bulb is a basal plate, basal plate contains the scales, and produces the plant roots.
Examples of true bulbs are such popular flower varieties daffodils, tulips and lilies.
True bulb varieties of plants are sensitive to drought and should be handled with care. When proper care, however, individual bulbs can live for many years without being planted.
The Cormo
A corm, like a true bulb, also contains a stem base, but tissue of the base is solid and has no scales seen in true bulbs. The roots grow from a basal plate which is located at the bottom of the corm, and the growing point is at the top of the corm.
Popular types of onions are gladiolus and crocus. Each corm lasts for a single season, and as the corm shrink after flowering, it forms a new bulb on top of it. In addition, small increases, called bulbils, there are some the base of the basal plate in the corm.
The Tuber
Like corm and true bulbs, a tuber is actually an underground stem base. A Unlike corms and bulbs true, however, the tuber does not contain a basal plate. Instead, the roots of the tuber grow from both the base and sides. A tuber will have multiple growth points out on its top surface.
The rhizome
The rhizome is actually a thickened stem that grows either in part or entirely underground. The point of greatest growth in a rhizome is located at one end, and additional growth points are located along the sides. The rhizome is the most famous bearded iris.
Tuberous roots
Unlike other types of bulbs, which are actually specially adapted stems, the tuberous root is not a true root. Instead, fibrous roots designed to absorb nutrients and water grow on the sides and tip of the tuberous root. Most tuberous roots grow in a group, and swollen tuberous parts radiate from a central point. The growing points of a tuberous root are found in the foundations of older stems, not the same roots. Dahlias and lilies are the best known examples of tuberous roots.
