R. Gravin Michel d'Ursel is a moschata hybrid, descending from Lavender Pinocchio x (Ballerina x Echo BRT).
This creation has been offered to the late Countess Nanda d'Ursel, by the famous Belgian rose-breeder, Louis Lens, a dear friend. It has been launched at Château de Hex during the first Rose-festival in 1994.

The Château de Hex was built in the 18th century on a beautiful natural site, by Count Charles-François de Velbrück. The first roses arrived in Hex in the 18th century during the reign of the Prince-Bishop and today these remain in the "Prince's Garden". Because these roses are not grafted but grow on their own roots, these two-century old plants, still flower abundantly throughout the summer. The gardens, park and woodlands have always been immaculately maintained. A collection of old and botanical roses - the oldest of which date from the original garden lay-out - is of particular interest. This collection is the fruit of the neverending efforts and joy of the late Countess (Ferdinanda Diana) Michel d'Ursel (1928 - 1997), who built up an exceptional collection in the unique surroundings of her gardens.
The rose garden received the World Federation of Roses Garden Award in 1997.

The gardens of Château de Hex are only open to public on the second weekend in June and September during the Festival of rare plants, roses & kitchen gardens. Nurseries specialised in old and botanical roses, as well as collectors and breeders of rare plants put their best products for sale. At the same time the public can attend exhibitions, demonstrations and lectures by professionals from Belgium and abroad on the most interesting subjects.

Hex is situated in the village of Heks in the commune of Heers, in the south of the Belgian province of Limbourg.
