All there is to know about the Pierre de Ronsard rose tree

History of the Pierre de Ronsard rose tree

The Pierre de Ronsard climbing rose tree is a hybrid. It is a combination of 3 roses, the ‘Danse des Sylphes’, ‘Haendel’ and ‘Kalinka’.

Marie-Louise “Louisette” Meilland, born in the Paolino family, was also from a renowned lineage of Italian rose breeders, and their love for roses was one of the traits that united them. Manou, as friends and family would call her, continued breeding flowers after her husband’s early death in 1958. The Pierre de Ronsard rose was noticed by a visiting horticulturist, M. Horstmann from Germany, who foresaw the appeal of a modern rose that looked like heirloom roses of old. The Meilland team followed through, for the greatest joy of rose-lovers to this day.

It went on to have particularly noteworthy introduction: though the initial name of the flower was “Ingres”, the final name chosen for the rose was suggested by Christine Jossien, working for the City of Paris Parks and Greens department. Indeed, 1985, the year the rose was scheduled for release, was the 400th anniversary of the famous French poet Pierre de Ronsard, and Paris thought it appropriate to dedicate a rose on this occasion to the man who spun the words still learned by thousands of schoolchildren today:

Mignonne, allons voir si la rose
Qui ce matin avait déclose
Sa robe de pourpre au soleil,
A point perdu cette vesprée,
Les plis de sa robe pourprée,
Et son teint au vôtre pareil. […]

Which, in English, might run as follows:

Sweet child, to the rose let us go
Which this morn had unfolded
In the dawn sun its violet robes,
For now ’tis dusk. Has it lost
The soft folds of its violet mantle,
And its glow so alike to yours? […]

In 2006, the rose tree earned the prestigious title of “Most beloved Rose in the World”, a title that awards recognition to the most beautiful roses in the world.

To this day, it is one of the most-sold rose trees on the planet.

Special characteristics of its flowers and leaves

The Pierre de Ronsard rose tree bears large double flowers that unfurl in a subtle gradient from white to pink. Its flowers mirror the characteristics of ancient heirloom roses.

Although the fragrance is rather discrete, the Pierre de Ronsard rose tree doubles down on an extremely dense and particularly long-lasting blooming since it extends from April to October-November.

Leafage is not also the poor parent, since its stark bright green marks a welcome contrast to its delicate flowers and colors.
