Cotoneaster glaucophyllus aka Glaucous Cotoneaster

Cotoneaster glaucophyllus is a shrub in the rose family. It comes from southern China, according to Kew. Plants For A Future also lists Vietnam within its range. It grows in mountain forests, clearings, thickets, and rocky places. Recorded sites lie around 3,940–9,840 feet [1,200–3,000 metres] above sea level. Some habitats have lime-rich soil. Common names include glaucous cotoneaster and bright bead cotoneaster.

This shrub keeps all or some leaves through winter. In gardens, it reaches 5–8 feet [1.5–2.44 metres] tall and wide. Wild plants can reach 16 feet [4.9 metres] in both directions. Dense branches rise upright or bend into arches. The plant can form thickets, giving it a full outline. Its oval leaves bear fine, silver hairs. Young leaves have a denser coat than older ones. Leaves reach about 2.5 inches long and one inch wide.

Small white flowers grow in clusters at the leaf axils. Bloom runs from May to July. Small, glossy fruits follow the flowers and add garden interest. The Missouri Botanical Garden lists this shrub as attracting birds. Full sun gives the best flower and fruit display. Light shade also suits it, though deeper shade is less well supported. Plants For A Future lists woodland edges among its garden settings.

Grow it in soil that drains well and stays evenly moist. It also copes with dry soil and brief drought. Suitable soils include sand, heavy clay, and stony ground. Poor soil, salt spray, and city conditions need not rule it out. The Missouri Botanical Garden rates it hardy in USDA zones 7–9. It describes the plant as easy to grow, with low upkeep. Use it in mixed borders, rock gardens, or seaside gardens. Its dense growth also suits hedges and screens. It has a place in dry-land garden schemes as well.

Fireblight, leaf spots, and canker can affect this shrub. Watch for aphids, cotoneaster webworm, and lacebugs. Mites may become a problem during hot, dry weather. Plants For A Future records a rose-tan dye from the fruit. It lists no known food or medicinal uses. That source also reports no known hazards. This does not establish that the fruit is safe to eat.
