Description
Magnolia trees (Magnolia spp.) bloom in early spring or summer and feature flowers of pink, red, purple or white. About 80 magnolia species and several hundred cultivars grow in U.S. Department of Agriculture plant hardiness zones 5 through 10. Depending on the species, magnolias may be evergreen, semi-evergreen or deciduous. The variety of magnolia growing in your landscape will determine its specific needs but in general, trees require acidic soil, full sun to partial shade and regular watering. Prune evergreen magnolia trees before spring growth and deciduous species just after they bloom.

Magnolia is a large genus of about 210 flowering plant species in the subfamily Magnolioideae of the family Magnoliaceae. It is named after French botanist Pierre Magn

Magnolia is an ancient genus. Appearing before bees did, it is theorized the flowers evolved to encourage pollination by beetles. To avoid damage from pollinating beetles, the carpels of Magnolia flowers are extremely tough. Fossilised specimens of Magnolia acuminata have been found dating to 20 million years ago, and of plants identifiably belonging to the Magnoliaceae dating to 95 million years ago. Another aspect of Magnolias that is considered to represent an ancestral state is that the flower bud is enclosed in a bract rather than in sepals; the perianth parts are undifferentiated and called tepals rather than distinct sepals and petals. Magnolia shares the tepal characteristic with several other flowering plants near the base of the flowering plant lineage such as Amborella and Nymphaea (as well as with many more recently derived plants such as Lilium).
