Our varieties

Our collection of iris and daylilies

The collection was created over 60 years ago by Doreen Bovet.

Like many Americans, Doreen loved iris. In autumn 1950, she ordered five new varieties from Schreiner, a renowned Swiss grower based in the United States, and had them planted in the Château’s vegetable garden. When the gardens were opened to the public in 1955, visitors were amazed to see so many different iris together. As the years have passed, their number has grown. Today, over four hundred varieties of iris and 13,500 daylilies extend for more than two hectares.

The iris, more robust and with more flowers, some blooming twice a year

The flowers we admire today are very different to the ones the first visitors saw. Today’s iris are more robust and produce more blooms. The flowers are carried on shorter stems (85cm on average, compared with 100cm), are larger and last longer. Their shape has changed too, with rounded rather than pointed petals and wide sepals that extend almost horizontally instead of hanging. Colours have also evolved, with a preference today for warm shades of honey, purple, rusty brown and mahogany, or subtle blends of pink, peach and cream. Breeders are still trying to achieve the perfect red.

Each year new varieties are introduced, thanks to which the collection remains one of the most interesting and up-to-date in Europe. Recent additions include reblooming iris which, in the right weather conditions, will flower a second time in autumn. During the summer months, visitors can admire the daylilies; 200 different varieties feature in the catalogue.

The daylily, worth getting to know

Daylilies are part of the lily family. Not all European gardeners are familiar with this plant, yet it has so much to offer. Its many-coloured flowers open in the first days of June and continue to blossom in abundance until mid-summer. Daylilies feature prominently in the gardens at Vullierens, where they take over from the more fleeting iris to provide a wonderful carpet of colour throughout the sunny months.

Recreate the elegance of Vullierens at home

The flowers are propagated by dividing the rhizome, meaning you can continue to enjoy part of these stunning gardens at home. Simply note down the reference of the flowers that catch your eye as you walk around, and place your order.

The gardens were created by the present owner’s mother. It was her wish that the proceeds from these sales go towards maintaining the Château and enhancing this piece of local heritage – a tradition that is carried on today.
