Prunus triloba aka Flowering Almond

Prunus triloba, or flowering almond, belongs to the rose family. Its native range covers northern and eastern China to northern Korea. It forms a dense shrub or a small tree. The plant loses its leaves each year. Its rounded shape suits gardens where a spring display matters. Garden plants reach about 8–13 feet [2.5–4 metres] tall and wide. They take about five to ten years to reach full size.

The dark green leaves often have three lobes. They turn yellow in fall before they drop. Pink flowers open on bare branches before the leaves appear. Each bowl-shaped flower measures about an inch across. The blooms have a scent and draw butterflies. Chicago records flowering in March and April. Elsewhere, the season runs from early to mid-spring. Small, round, red fruits follow the flowers. Birds visit the plant for its plum-like fruit. The supplied species sources do not establish human edibility or toxicity.

Full sun gives this shrub its preferred growing conditions. It also accepts partial shade in a sheltered site. It needs moist soil that lets excess water drain away. Moderate fertility and moderate watering suit it. It grows in chalk, clay, loam, or sand. Acid, neutral, and alkaline soils are all suitable. The RHS rates its cold hardiness as H6. Chicago lists USDA zones 3–6 for the species. Late frosts can harm the early flowers despite this hardiness.

Use flowering almond alone or in a small group. Its spring flowers make it useful near a patio. Growers can train it into a standard with a trunk. It also fits courtyard gardens and informal flower borders. Birds and butterflies add value in a wildlife garden. Seeds can be sown in outdoor containers during autumn. Softwood cuttings taken in early summer need heat from below.

This plant has a medium level of maintenance. Aphids, scale insects, borers, and caterpillars can attack it. Japanese beetles and spider mites may also cause trouble. Disease risks include leaf spot, powdery mildew, and black knot. Cankers, blossom wilt, brown rot, and silver leaf can occur. Honey fungus and verticillium wilt are further risks. The RHS also flags it as a high-risk host for Xylella fastidiosa. These risks matter when choosing it for a garden.
