Grana Gram

Every garden is a seed ready to bloom.

Did you know the « granas » are the tiny chlorophylle beds in the plant leaves ? They transform light into plant energy, and initiate beauty in a garden. Grana is also the latin for seed - seeds that hold infinite possibilities and promises. So Grana Gram refers to light and seeds key role in creating beauty, diversity and life.

Ariane Cojan - founder

I decided to combine my passion for beauty, gardens, drawing and sciences by becoming a garden architect, after a 15 year career as a project manager in a global company. I am french, and have lived abroad several years in Italy and in the United States. I am experienced working in international environments, and will be delighted to help you create the garden you wish, in France.

Since June 2021, I am vice president of the professional network "Les concepteurs de Jardins" that reunites over 50 passionate and demanding garden architects.

I participate to the Arbusticulteurs network, an NGO that promotes professionnal pruning of shrubs and small trees, a great opportunity to exchange with peers and continue to build expertise.

In 2023, I was honored to be invited to the jury for the 116th International Competition for New Roses of Bagatelle, Paris.

I joined the Climate Fresk and Soil Fresk networks to facilitate 3 hours workshops. These serious games aim to raise awareness on the human impact to climate and fertility of soils - topics dear to my heart and key to my Garden Architect activity.
