Chaenomeles cathayensis

Chaenomeles cathayensis, or Chinese flowering quince, belongs to the rose family. Its native range runs from Tibet through central and southern China to northern Myanmar. It grows in scrub, hedges, forest edges, and roadside sites. This deciduous plant forms an upright shrub or small tree. Garden plants reach about 8–13 feet [2.5–4 metres] tall and wide. They take around five to ten years to reach full size.

The stems bear spines, and the branches form a bushy crown. Mid-green leaves have a narrow, lance-shaped outline. They can reach about 0.4 feet [0.12 metres] long. Small flower clusters open in early to mid-spring. Each white flower has a pink flush. Flowers measure about 0.13 feet [0.04 metres] across. Large, scented fruit follow, with yellow-green skin. They can reach roughly 0.5 feet [0.15 metres] in length.

Grow this quince in full sun or partial shade. It suits moist soil that drains well. It accepts chalk, clay, loam, and sand. Acid, neutral, and alkaline soils can all support it. Very alkaline ground may cause chlorosis, despite its tolerance of lime. The RHS rates its hardiness as H6. Plants For A Future lists USDA zones 4–8. Sites may be exposed or sheltered, with any aspect. Summer semi-ripe cuttings and autumn layering offer ways to raise new plants.

Its spiny growth suits hedges and screens. It also fits cottage gardens, coastal gardens, and wildlife plantings. Gardeners can train it against a wall or grow it beside one. Its spring flowers and large fruit give it ornamental value. Aphids and scale insects may attack it. Possible diseases include fireblight, blossom wilt, and brown rot. Honey fungus can occur, though the RHS lists it as rare.

The fruit tastes harsh when raw but develops fragrance when cooked. It can supply jams, jellies, and fruit for apple pies. Remove the seeds before preparing fruit for food. The RHS warns that seeds contain toxins and pets should not eat the fruit. This warning is more specific than PFAF's report of no known hazards. PFAF also records medicinal uses for the fruit. These include treatment of digestive complaints, vomiting, muscle cramps, and rheumatic pain. Those reported uses do not establish safe or effective home treatment.
