Leaves 9~10 cm wide with a leaf length-to-width ratio above 3 are top grade; leaves 6~8 cm wide with a length-to-width ratio of 4~6 are next. Leaves 2~2.5 mm thick are top grade; leaves that are thin or overly thick are both inferior. Leaves that stand upright are top grade; those that lean or arch and droop are inferior. A gap between leaves of two fingers or less is top grade; gaps that are too wide or too narrow are inferior. Generally, leaves with a round, blunt tip are top grade; leaves with a pointed, elongated tip are inferior. A glossy leaf surface with shine on both sides is top grade; a darker leaf color with shine on only one side is medium grade; one that is not shiny and looks dull is low grade. Leaves whose veins are clearly raised, up to 1.5 mm high, with wide spacing between veins, forming a "field" or "sun" shape, are top grade; leaves with smooth, hidden veins are inferior. A thick, round flower stalk is top grade; a flat, thin flower stalk is inferior. Large flowers in great numbers with a brilliant red color are top grade; small flowers in few numbers with a pale red color are inferior.
The large-flowered clivia has strong growth vigor and is simple to cultivate and manage. With proper care, its leaves are deep green and glossy, its flowers are brightly colored, large, and numerous, and a single plant can send up 2-3 flower stalks, continuing to bloom through winter. This greatly enhances its ornamental value and extends the viewing period.
