Le Coucou, ou Primevère officinale

Le coucou, ou primevère officinale, est une primevère sauvage bien présente dans nos campagnes. Cette fleur forme, au bout de longues tiges, de petits bouquets de fleurs jaunes.

Le coucou pousse souvent dans les sous-bois ou dans les prés, au bord des chemins, sur les talus. La floraison est précoce : le coucou est l'une des premières fleurs à s'épanouir, en avril. Il dégage, de plus, un agréable parfum sucré, qui favorise sa pollinisation.

Amateur de terres calcaires, le coucou est une plante assez rustique. C'est une plante vivace facile à entretenir: année après année, le coucou forcit pour former une touffe sans envahir néanmoins votre jardin. Le coucou possède un rhizome assez court.

L'adopter dans son jardin

Le coucou est une petite fleur décorative, de culture facile, appréciée dans les jardins. Elle donnera à votre extérieur une jolie allure naturelle.

Le coucou fleurira un an après sa plantation, à condition que la germination ait eu lieu avant le mois d'août.

Le coucou apprécie les sols argileux, un peu calcaire. Inutile d'ajouter du terreau ou de l'engrais : le coucou a besoin d'un sol assez pauvre. Choisissez un emplacement ensoleillé au moins une partie de la journée.

Semez les graines de coucou sur sol propre, puis arrosez. La germination a lieu sans difficulté. Les feuilles du coucou ressemblent à celles des autres primevères.

A savoir : le coucou, d'origine botanique, possède des parents (groupe Polyanthus) qui lui ressemblent fortement mais présentent des coloris variés.

Les vertus du coucou

Le coucou est connu depuis longtemps pour ses vertus médicinales.

En infusion, le coucou serait sédatif. En faisant macérer les feuilles, on peut obtenir une décoction qui aurait une action sédative sur les bleus et blessures non ouvertes.

Le coucou peut aussi s'utiliser en cuisine, par exemple pour agrémenter des salades.

I just got to NJ Ticket Lookup , but I found this awesome website, triberr.com that helped me look up the information regarding https://www.njmcdirect.com I needed to take care of it quickly and easily via Victoriarptg! I love the convenience of being able to Pay Traffic Ticket online New Jersey. NJMCDirect website so much easier than having to go to the courthouse and stand in line. I would highly recommend this service to anyone who has received a traffic ticket in New Jersey. “I found the best deal on cplusplus.com when I was looking for NJ Tickets to a concert. They had great prices and the customer service was amazing.” I got a traffic ticket in New Jersey and was dreading having to go to court. But the Municipal Court system was easy to use, and the whole process from https://www.credly.com/users/pay-nj-parking-ticket/badges was over before I knew it. I’m really glad about visiting the http://www.NJMCDirect.com.

Pruning and trimming trees is not only essential for their aesthetic appeal but also for their overall health and vitality. By removing dead or diseased branches, we promote new growth and prevent potential hazards like falling limbs. It's like giving the trees a well-deserved haircut, allowing them to flourish and thrive in their surroundings.
