Description of Sunflower

Sunflowers are one of the most beautiful flowers in the world. A welcome sight in any garden's sheer splendour and meadows of wildflowers, they signal the arrival of the long summer months, creating positivity and warmth with their bright sun-like appearance." The sunflower looks very attractive, but it is odourless.

The Sunflowers

The Sunflowers.


It is an annual plant of large proportions, reaching more than 3 metres in height. It is a plant with few branches, and the stem is thick, straight and large. It has deep roots formed from one main root and abundant secondary roots. Its leaves, 5 to 30 cm long and half as wide, are large, oval, carefully toothed, leafy, with three main veins and rough to the touch. 


The upper leaves are alternate, and the lower leaves are opposite. The inflorescence, also known as the flower head, is large, 10 to 30 cm in diameter and contains hundreds of small tubular flowers.


In the outer part, we can find ligula or external sterile flowers in one or two rows which look like petals. These flowers, which appear from summer to fall, are golden yellow and have no direct reproductive function, but they act as an attraction for insects, which help the plant in the process of pollination.


The fertilised flowers develop in their receptacle – in the same provision as the honeycomb – into one of the most popular oleaginous fruits in the world: the "sunflower seeds". They are angular achenes, 8–15 mm long, oval, and flattened, with the pericarp (or outer covering) glossy black, white or striped, depending on the variety. 


When the plant is fertilised, when mature, it has between 250 and 1500 flower heads, depending on its size and the number of flower heads the plant has. Plants with only one inflorescence have a higher seed content, whereas plants with multiple flowers have fewer seeds. 


The back of the flower head is composed of a series of stem-like green segments. The flower head presents the heliotropic motion produced by rotating the stem in a nurturing process. In the evening, the stem gradually returns to its upright position. At maturity of the sunflower plant, that is, when it does not produce many seeds (from 35–40 days after flowering), the back of the flower head turns yellow and its bracts turn brown.
