Flowers
The Roure Arboretum protects the flowers of our mountains ; on the one hand, those that grow spontaneously on the alpine lawn, and on the other hand, some rare or endangered species including, in particular, a collection of wild roses.
It is important not to pick the protected flowers of the Arboretum.
For several years, the Arboretum has undertaken a large census to know all the richness of the floristic heritage of the site. Thus, the sheep sorrel, the flexuous canche or the fragrant fluuve like acid soils, and rub shoulders with species that appreciate calcareous soils, such as the Arabettes tourette or the common thyme and wild thyme.
Spontaneous Flora
Viola Valderia Allioni
On an alpine lawn with hundreds of species of plants and flowers, in the middle of all the others, the Viola Valderia Allioni has long gone unnoticed. It is however a rare and endemic species of the Alpes-Maritimes.. To preserve the Viola valderia and a few others, the Arboretum Marcel KROENLEIN has dedicated part of its site to them.
Please note that the Violette des Alpes de Valdieri and the Rose de France are protected species. Don't pick them!
Introduced Flora
The collection of Rosa Rosa, Rosa, Rosam…
One of the particularities of the Arboretum Marcel Kroenlein is to have, for the first time in France, brought together the heritage of the wild roses of the Maritime Alps, by creating the Aire aux Rosa, which earned it the Henry Ford Environment Prize for France.
The rose has always been appreciated, venerated, cultivated, used for its medicinal properties, painted, sculpted, embroidered… especially in these two cradles of origin which are China and the countries of the Mediterranean.
The Rosa appeared on the earth 40 to 60 million years ago and have passed through the centuries being better known as rosehips. It is thanks to these wild roses and clever hybridization that the beautiful roses in our gardens are born.
Succulents
Little "fat" plants
They spring from our mountain paths and rockeries, and have as many names as stories, real or imaginary.
Houseleeksare classified among the "succulents" because they are full of juices. Since ancient times, this plant has been credited with the power to deflect lightning, hence its Latin name "jovibarba" which means "Beard of Jupiter“.
For scientists, they are "sempervivum"; from semper (always) and vivum (alive). But for children, they remain "little artichokes", even "little cabbages"...
