Desert willow (Chilopsis linearis), with its delicate, pale green leaves and large, fragrant flowers, loses its leaves in winter. A North American native, desert willow grows wild in the southwestern United States and Mexico. It commonly grows in desert areas that flood seasonally, like stream beds and low canyon areas.
A tree loses its bark as it grows and new tissue develops to replace the old. A tree loses its bark for many reasons, and in most cases, it's not an indication that anything is wrong. The most common cause of tree bark loss is that it is growing out of its skin, which must be shed to allow its trunk to enlarge. In other cases, tree bark may fall off due to insect infestation, disease or animals attacking it for different reasons.
