General Description:

The annual fleabane is an annual to biennial flower, with an erected stems, rather stiff, like herbaceous plant. Its size is thirty centimeters to one meter.

The primary root is elongated and from pivoting type.

The stem unicaule or branched is thirty centimeters to one meter on average. It is erected and has alternate leaves on all its height.

The leaves are like alternate, simple, entire or broadly oval toothed and have a hair more or less abundant. The basal leaves are more expanded and have a blade that is shrinking as a petiole.

Flowering takes place from April to July, depending on the region.

Flowers white and yellow, are grouped in racemes of flower at the top of the stems. The flower heads are surrounded by an involucre semi-spherical, composed of roughly equal bracts, tight. The external flowers are numerous, wider than the involucre rather spread outwards, flat. The tubular flowers, in the middle are less numerous and yellow,

Pollination is entomophilous or autogamous. Sexuality is hermaphrodite.

The fruit is a small achenes covered with hair. The seeds are diseminated by spreading from the wind. The plant name in Greek means « old man early », probably because the fruits sometimes bear white tufts at the end of spring.

Guzel netlik ve kompozisyon..Elinize saglik

Bonjour Philippe,
Très belle publication avec macro, bien composée, permettant d'apprécier la finesse des détails et la délicatesse des couleurs.
Je regrette la concision du commentaire.
A bientôt sur TN pour de nouvelles aventures.

This is called a simple and beautifull shot,, very nice

Hallo Phillipe
This image is just proof that even a simple flower can turn out to be a great photograph and one do not always have to take pictures of tiny insects, colourful birds or unusual mammals to be seen as a good photographer. This is a basic and very straightforward image, but unique and eye-catching because your technical skills was used to its best. This is great image, with details well seen and displayed. Thanks for sharing. Best regards.
