About Deciduous Azalea
Better placed than the evergreen azaleas where deer are resident, because bare winter stems give them nothing to browse in the hungry months. The native flame azalea is among the most spectacular shrubs in North America. Needs acid, sharply drained soil that stays moist, which is a narrower requirement than it sounds.
