These plants derived from Mexico mountains. Dahlia including ornamental plants cultivated late.
 

In Europe farming began in 1789, from the Royal Botanical Garden in Madrid, Spain and spread throughout Western Europe. Although development very slow, in 1841 there were already 1200 varieties. Plants cultivated dahlias consists of a tall tree dahlia bias reaches a few meters and shrubs (woody plants but still low). Dahlia flower has a white, yellow, orange, violet, red, purple or a combination thereof.
 

Dahlia name taken from a man who was instrumental in developing and popularizing these plants is Professor Andreas Dahl. Dahlia plants so many kinds, but 12 of the 20 types derived from Guatemala and Mexico, and 6 kinds of them have been developed into an ornamental plant. The species is famous dahlia Dahlia pinnata, this plant has developed into more than 2000 kinds for horticulture.
 

Based on the form of flowers, dahlias can be divided into eight faction, namely Cactus dahlias, Single dahlias, dahlias pompons, Decorative dahlias formal, informal Decorative dahlias, dahlias Collarette, Anemone Peony dahlias and dahlia.

 Here are explained on growing conditions from planting dahlia: 

a. Climate conditions 
Dahlia plants can grow well and productive environment flourishes in conditions of cold air (cold). Dahlia plants can grow well in the area that rises 560-1400 m above sea level, with air temperature range 14 0-18 0 Celcius. (minimum) and 19 00-30 0 Celsius (maximum). However, growth and flower production is influenced by factors of air temperature and sunshine. Conditions ideal for plant growth is at a temperature of dahlia 10-15 degrees Celsius in the open and getting enough sunlight. Indicator ideal growing environment for plants dahlia can be seen from the climatic conditions in the district center of production of ornamental plants and cut flowers. 

b. Soil conditions
  
Dahlia plants have the broad adoption of the types of agricultural land. Terms to be watched in the selection of land for crop cultivation dahlia is fertile soil, loam, contains a lot of organic material, Aeration and drainage good, and prioritized contain more nutrients phosphorus (P). tarnish or waterlogged soil will facilitate root rot diseases, so risk of root rot and root outbreak stem dahlia plants.

Dahlia plants in general can be developed in three ways, namely by seeds, cuttings, and with the grass roots. However, the development of science and technology dahlia plants can be propagated by tissue culture. To learn techniques of tissue culture multiplication as well, please see the previous article.
