Are magnolias evergreen or deciduous?

Question

Which plant genus, with species ranging from low deciduous shrubs to evergreen trees up to 18 m (59 ft) tall and native to areas of Eurasia and Africa, flowers prolifically with dense pink spikes?

Answer 1

It depends on the species and/or the temperature of the habitat
Some species are deciduous and others usually evergreen. However, evergreen magnolias can change. Most evergreen magnolias thrive where temperatures in winter are mild, or cool but not freezing, but if planted in colder climates can change to deciduous.
