It's been several years since I got this rose bush from you. It's so beautiful that it's become one of my favorites, and in fact, I think I'll treat myself to another one soon. Our land is made up of a mixture of flint, tuffeau, and very chalky soil. If we're lucky, we might come across a clay pocket! Despite all that, the rose bush has withstood everything, even the terrible hailstorm on June 4th, 2022. In short, I can only highly recommend (in every sense of the word) this marvel!

Planting and care

To achieve abundant flowering in your roses, it is necessary to regularly bend and tie the branches that can grow in the summer up to 1 m (3ft) in a week. Each bending results in a lateral shoot that ends in a bouquet of flowers. Do not hesitate to use this technique, you will be rewarded.

Roses are often stained or unsightly at the end of summer, but it is not a problem for their development. These stains are not harmful to the rose, it is a natural phenomenon.
