Intergeneric hybrid of the Asteraceae family, resulting from the cross between a Raoulia and Leucogenes grandiceps, a New Zealand high mountain species from the South Island, sometimes referred to as South Island edelweiss. The two genera are phylogenetically close, making their hybridization possible. The exact parentage on the Raoulia side is not established with certainty in the available botanical sources.
This hybrid forms a very compact and rounded cushion, dense, only a few centimeters high, composed of multiple rosettes tightly packed together. The leaves are small, spatulate, covered with a silky white-silver tomentum that gives them a very particular velvety and pearly appearance. The overall habit evokes an assembly of small silver stars, inheriting both the tight cushion habit of Raoulia and the characteristic woolly tomentum of Leucogenes.
In cultivation, it requires perfect drainage, a lean and mineral substrate, full light, and rigorous protection against any stagnant moisture in winter. It is generally reserved for cultivation in a cold greenhouse, alpine trough, or under glass shelter, and is intended for collectors with solid experience with New Zealand alpine plants.
