The beautiful planting season

For its autumn 2026 edition, the theme shines a spotlight on beautiful and nourishing plants: varieties that combine decorative appeal with edible abundance. As gardens glow with fruit, berries and the season’s final blooms, this theme celebrates plants that beautify outdoor spaces while offering harvests, fragrances and flavours. True allies of biodiversity, they encourage a harmonious balance between beauty and usefulness, transforming the garden into a living, generous space firmly connected to nature. A wonderful opportunity to rethink the structure of your garden and combine beauty with purpose. For three days, the Château will come alive to the rhythm of nature!

The festivities do not stop there! Activities for children and adults, inspiring talks, and the presentation of awards and trophies will bring these plant-focused days to life. Visitors of all ages can take part in fun and educational workshops, promising friendly moments and discoveries for the whole family.
