"Try to find this rare flower under the shelter of a large rock. This well-named plant, which ""breaks up rock,"" is lodged in the rock crevices. And not just any! This very rare protected plant can only be found in France in some localities of the Hautes-Alpes, and only in Bessans in the department of Savoy. So come and admire the rarity of these grey-blue lanceolate leaves grouped into flattened pads. If you are here in July, a panicle of beautiful and immaculate delicate flowers will spring up for you."
