Dandelion clock
 |
|
| [Note Guidelines] Photographer's Note |
The flower matures into a globe of fine filaments that are usually distributed by wind, carrying away the seed-containing achenes.
This globe (receptacle) is called the "dandelion clock", and blowing it apart is a popular activity for children worldwide. In German it's called a Pusteblume, translated as "blow flower."
The flower head is surrounded by bracts (sometimes mistakenly called sepals) in two series.
The inner bracts are erect until the seeds mature, then flex down to allow the seeds to disperse; the outer bracts are always reflexed downward.
Some species drop the "parachute" (called a pappus, modified sepals) from the achenes. Between the pappus and the achene, there is a stalk called a beak, which elongates as the fruit matures.
The beak breaks off from the achene quite easily. |

Magnifique, je rêve d'en faire autant mais mon jardinier ne me laisse aucun pisenlit, je vais aller chez le voisin. Trève de plaisanterie, cette photo est superbe avec son Bg noir qui met tout en valeur.
Bravo

memories of childhood here Jean Francois. Very good capture looking great against the dark background. Great detail, highlights and shadows in the flower head. All very intricate and sharp. Great one
