These taller cotoneaster are less common in landscapes, but are occasionally planted for their attractive flowers and foliage and showy fruit.
These hardy woody plants bear small (or occasionally larger), rounded, leathery leaves that alternate along trailing to erect, straight to zigzag stems. Leaf color ranges from deep- to gray-green, with deciduous cotoneasters often turning brilliant hues in fall. Small, solitary or clustered, unscented or faintly malodorous flowers open in late spring or summer in shades of white. They are a favorite of bees. Spherical, berry-like fruits follow the flowers, ripening to red, black, orange, or yellow in late summer, sometimes to spectacular effect. The "berries" persist until late winter or early spring before being harvested by birds and other wildlife.
Plants are adaptable, doing well in full to partial sun and moist, well-drained to heavy soil. Tolerate seaside conditions. Are perfect for massing on slopes and walls, where their cascading growth and eye-catching fruit can show to best effect. Their interweaving branches trap blowing leaves and other debris, giving them a somewhat deserved reputation as "trashcan plants."
These cotoneasters make good candidates for shrub borders and hedges. All cotoneasters are susceptible to fireblight.

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)
