Leaves - Alternate, or appearing fascicled at the tips of short shoots arising laterally from older branches, folded lengthwise during development, short-petiolate to nearly sessile, the petioles to 5 mm long, glabrous. Stipules present only on vigorously elongating young branches, 5-10 mm long, leafy, kidney-shaped to heart-shaped, the margins finely toothed, shed as the leaves develop. Blades 1.5-10.0 cm long, simple, unlobed, elliptic to elliptic-obovate, tapered at the base, sharply pointed, the margins finely and sharply toothed, the upper surface shiny, glabrous, the undersurface dull gray-green, glabrous or sparsely hairy along the main veins when young.

Petals 5, 13-22 mm long, free, broadly obovate, clawed, orangish red to red, less commonly pink or white. Stamens numerous, the filaments glabrous, to 1 cm, the anthers 1-2 mm long, yellow. Pistil 1 per flower. Ovary inferior, the tip usually moderately hairy, with 5 locules, each with numerous ovules. Styles 5, fused toward the base, the stigmas 2-lobed, the lobes often somewhat elongate along opposite sides toward the tip of the style. Ovary inferior, 5-locular. Placentation axile.

Fruits - Pomes, 30-70 mm long, globose or ovoid, glabrous, yellow to greenish or brownish yellow, with small lighter-colored spots at maturity, with numerous easily exposed seeds embedded in the "core" of leathery carpel wall remains and the fleshy portion, this with small clusters of gritty stone cells. Fruits bitter in flavor, rarely produced in Missouri.

Flowering - March - May.

Habitat - Cultivated.

Origin - Native to Asia.

Lookalikes - None.

Other info. - This is a popular plant in cultivation in Missouri and elsewhere, and is used as a landscaping shrub and sometimes sculpted into hedges. Escapes from cultivation in Missouri are rare.

The common name is "flowering quince," but true Quince is a different plant, Cydonia oblonga Miller (Rosaceae). The fruits of C. speciosa are edible but very astringent and unpleasant when raw. They can, however, be used to prepare liqueurs, marmalades, and preserves, and are high in vitamin C. They have also been used in folk remedies. The flowers are typically pinkish-rose but the purely red form, sometimes called f. rubra, is very common also. There is also a white cultivar called "Snow." A synonym for the species is C. lagenaria.
