Intergeneric hybrid of the Asteraceae family, resulting from the cross between Raoulia eximia and Leucogenes grandiceps, two species from the rocks and high-altitude scree of the South Island of New Zealand. The hybrid was described by T.F. Cheeseman, a New Zealand botanist from the late 19th and early 20th centuries, author of the Manual of the New Zealand Flora.
It forms a compact and rounded cushion, very dense, composed of numerous tightly packed rosettes with spatulate, grayish-green leaves, abundantly covered with a white-woolly tomentum that gives them a downy and slightly pearly appearance. The well-individualized rosettes interlock closely to form an irregularly knobby surface, evoking tiny pale silvery-green cauliflowers.
The available data on its flowering in cultivation remains insufficiently documented to be indicated here with certainty.
In cultivation, it requires perfect drainage, a very mineral and poor substrate, full light exposure, and absolute protection against stagnant moisture in winter. It is reserved for cultivation in a cold greenhouse or under glass shelter, and is intended for experienced collectors in the cultivation of New Zealand alpine plants.
