​

Cotoneasters are mostly landscape plants and they will survive in a great part of sunlight. In the winter the roots needs to be protected from severe freezing. Bring indoors when bad frost has been forecasted. A cotoneaster may be kept indoors all year round as long as it’s exposed to a lot of sunlight. In cold climates the cotoneaster is deciduous and in warmer climates they can be evergreen.
