Domestic mountain ash, known as corms, can be grown at home. The cormier measures 10 to 20 m high and 5 to 8 m wide when mature.
The fruits look like small pears or apples, depending on the cultivar. The tree is drought resistant but it is preferable to water it regularly for the first two years, in spring and summer. The leaves are composed of leaflets and measure approximately 20 cm. They change from green in summer to orange-yellow and then red as fall approaches. It is a real treasure for biodiversity. Its flowers attract pollinating insects and its fruits, the corm's, delight birds. It can grow up to 20m high when mature, and several meters wide.
