Description
Magnolia –
There are about 125 species and countless cultivars of fast growing, deciduous, and evergreen trees and shrubs, in this genus. They occur in woodland, scrub, and on riverbanks from the Himalayas to Eastern and Southeastern Asia, and from Eastern North America to Tropical North and South America. They are grown for their showy, solitary, fragrant, usually erect, sometimes pendent or horizontal, cup, saucer, goblet, or star shaped flowers, often borne before or with the leaves. The flowers have usually 6-9 petals, colors include pure white, white flushed or stained pink or purple, pink, rich purple, creamy yellow, greenish yellow. The alternate leaves are usually oval and smooth edged and in a few species, the foliage turns yellow in autumn. Cone like, cylindrical fruits, often pink or red with red or orange coated seeds, are attractive in autumn.
Grow magnolias as specimens among other trees and shrubs. Some species take many years to flowers.
