As a flowering species, this is the finest in this section, forming large and elegant depressed rosette-like leaf-crowns, 6 to 8 inches across, each formed of densely set circle-like rays of rigid silvery marginal linear leaves, producing a large and noble densely-flowered conical raceme, 18 to 24 inches high, of pure white salver-shaped blossoms.

As a decorative-leaf plant for summer gardens, it forms a fine companion plant to the Echeveria group in forming geometrical lines, belts, and double-edgings. It is also admirably adapted for ornamental panel work as link groups, and to show its effective character thus it requires to be grown in quantity.

Its beautiful leaf-crowns increase in size from year to year if not checked in growth nor permitted to bloom. If less glaucous in effect than the Echeveria, it is far less formal, more graceful in its outline, and far more elegant in the partial curvature of its leaves, whilst the silvery sheen of its leaf surface, seen under the brilliancy of a summer's sun, imparts to it an interest and beauty unequalled by any of its allied species, amongst which it has not been unfitly termed the Queen of Saxifrages.
