This upright deciduous shrub is notable for a display of red berries and vibrant red-purple leaves in autumn. The many upright branches of this native of central and western China bear dark green glossy leaves. In very late spring or early summer, scores of tiny, pinkish white flowers line the branches, and once pollinated by bees produce dark red berries in clusters. The fall foliage is glowing red to reddish-purple and is long lasting, as are the fruits.
Spreading cotoneaster is an adaptable shrub, tolerating a wide range of soils and pH but performing best in a fertile, moist, well-drained soil in full to partial sun. It makes a terrific hedge or screen, sheared or not, but an unpruned, natural look is prettiest and best for the display of flowers and fruits. Grow it as a specimen in any urban landscape, as a foundation shrub, or as a windbreak near the sea. (source: learn2grow.com)

1. Rub each seed lightly with a nail file softening the hull. Store the seeds in a plastic bag filled with moist sand inside the refrigerator for three months to cold-stratify them.
2. Sow the cotoneaster seeds in 10-15 cm (~5") plastic pots filled with sterile loam. Sow two seeds in each pot to a depth of the seed size. Sprinkling sand across the soil’s surface helps slow the evaporation rate.
3. Place the potted cotoneaster seeds on a propagation mat near a source of very bright light. Set the temperature on the propagation mat to +25C (77F) for nine hours each day. Adjust the temperature to +12C (55F) for the remainder of the day.
4. Water the cotoneaster seeds as often as necessary maintaining moisture in the top one-half inch of soil at all times. Add the water very slowly when irrigating keeps from disturbing the seed.
5. Watch for germination in 25 days. Remove the weaker of the two cotoneaster seedlings from each pot if both germinate. Wait until the seedlings reach 2,5-3 cm (~1") in height before thinning.
6. Move the cotoneaster seedlings to a sheltered spot outdoors with limited exposure to strong, direct sunlight. Continue watering, but allow the soil’s surface to dry slightly between waterings.
7. Slowly acclimate the cotoneaster seedlings to strong sunlight in the course of one week until they withstand full sun for five hours without wilting.
8. Transplant the cotoneaster seedlings into a sunny bed at least 75 days before the first autumn frost. Space the seedlings 3 m (10') apart. Mulching heavily around them protects their developing roots. (info source: ehow.com)
