Is Black mulberry always deciduous? I have a black mulberry ( _Morus sp._ ) in my garden (or 2 actually). According to the information I could find it is a deciduous tree). The trees in my garden do indeed lose their leaves. However, as most native trees start to color yellow/brown/red in september and have lost all leaves by now, the mulberry doesn't. It remains green until the frost kicks in and only then drops its (still green) leaves. It almost looks like it doesn't want to drop its leaves, but is forced to so so. This can be seen at the picture below. Hence my question: Is mulberry also deciduous in warm winters such as the mediterranean? And is it normal that leaves are still green when dropped? ![enter image description here](

The trees are generally deciduous in temperate regions, but trees grown in tropical regions can be evergreen.
