Dahlia flowers

Dahlia is a kind of plant that blooms with beautiful and luminous corollas, and enriches gardens and floral arrangements for cutting.
Its origins are exotic: it was born in Mexico and was brought to Europe by Spanish conquistadors around 1600, however, even before reaching their destination, botanists from the old continent had made a case study, thanks to the descriptions of the explorers of the time .
Once arrived in Europe, the dahlia did not have the role of an embellishment flowering plant, but it was tried more and more times to make the tuber, an edible ingredient.
Evidently these culinary experiments must not have been very successful, if, to date, the plants and flowers of dahlia, are widespread in gardens and floral compositions, and if, indeed, Dalia has become a name of a female person.
This passion for dahlias is due to the beauty and their ease in cultivation: they are plants with majestic and abundant flowering, which require few tricks, so they are the favorite of those who have a green thumb and, for these characteristics, are a good start for gardening newbies.
The floriculturists have classified the dahlia hybrids as Dahlia variabilis, indicating in the name, how much they can be multiform and multicolored, which is why, in the language of flowers, the dahlia is equivalent to the instability of the feelings and to the volubility of the behaviors.
Especially in past centuries, receiving a beautiful bouquet of dahlias meant that one was rather moody and fickle in feelings!
Today, opting for a composition of dahlias does not have such a strong value, but is a choice of taste and elegance.


All the most common garden hybrids are grouped under the name of Dahlia variabilis; these then, in turn, are divided into two large groups, the border dahlias and the flowerbed dahlias. Each group differs from the other in a characteristic way.
The flowerbed dahlia has plants about 30 centimeters, obtained from seed, which have a less exotic appearance in the flowers but very variable in color.
Border dahlia has a greater variety in the flower: there are eight!
1. Simple flower dahlia: each flower head has a central disk and a single outer ring of flowers
2. Dahlia with anemone flower: the flower heads are double and have large and flattened external flowers that surround the more internal and short ones.
3. Dalia a collaretto: the flower heads have an outer ring of flowers with a large radius, and a ring with more flattened flowers around the central disk.
4. Peony flower dahlia: two flattened flower rings develop around the central disk.
5. Decorative dahlia: it is the most widespread and known variant, it does not have a central disc but only slightly pointed and flattened flowers.
6. Dahlia ball: it is the most suggestive and rich variant. The flower head is very voluminous with spirally arranged flowers.
7. Dalia a pon pon: it is a smaller and miniature version of the ball variant.
8. Dalia a cactus: the flowers are thin, narrow and elongated.


Dahlias can reproduce in three different ways. Obviously the man can intervene in this step to obtain shapes and colors at will
Seed production begins with spring, sowing seeds of bedding dahlia, or other types, under glass until small seedlings are obtained. When they are less fragile and small, they will be placed in jars and always strengthened under glass.
The flowers born from self-reproduction will almost never have the characteristics of parent plants, which is why, this technique, although natural, is not ideal for those who want to have homogeneous plants and flowers.
To get the same plants as the "mother", there are two very specific techniques.
Division of the tubers: it consists of dividing a tuber in half shortly before replanting it. Each portion will then be potted at a temperature of around 16 °, keeping the laying soil as wet as possible. When the seedling is large enough, it will be planted in the ground.
Multiplication by cuttings: carried out by taking the tuberous roots and placing them in boxes with damp peat. It will be enough to wait for new jets to snack and grow about 10 centimeters. At this point you can cut and put in jars with sand and wet peat.


Treating dahlias is not complicated, just consider what climate they live in. A milder climate will allow the tuber to rest in its own soil, while a more rigid climate, especially if frosts are frequent, will require them to faint.
So, just before the autumn stiffens, it will be good to extract the tubers from the soil and let them dry in the dry air, under dry leaves.
In February-March the tubers can be planted again, in holes 10 cm deep and spaced 60 cm apart from each other.
The soil must be very fertile: then enriched with manure and bone meal.
If everything has been prepared for the best, you can enjoy, from spring to summer, a garden with splendid dahlia flowers.
We have said that the dahlia needs moist soil, which is why it needs to be treated more in the summer, especially if it is dry. The plants must always be kept very moist, using straw mulch to place around the base of each plant.

    This admirable idea has to be purposely

    I'm sorry, but in my opinion, you are wrong. I'm sure. I propose to discuss it.
