DistributionThroughout the Coastal Plain, and present in the extreme eastern and southeastern Piedmont, inward to Orange and at least Richmond counties.

This is a mainly Coastal Plain species, ranging north to NJ, and south to the Gulf Coast in FL and eastern TX. It does range well north inland in AL MS, and AR.
AbundanceIn the Tidewater zone, it is abundant and found very easily. Common to abundant elsewhere in the Coastal Plain away from tidal water. Uncommon in parts of the eastern Piedmont, such as Wake County. It is possible that the species is adventive in the Piedmont, or at least spread into this province by birds excreting the seeds; it may originally have been restricted to the Coastal Plain.
HabitatThis species is ubiquitous around the edges of salt and especially brackish marshes, and as an understory plant in pine stands or wet thickets and maritime forests, close to tidal areas. Farther inland it is often found in pools, marsh edges, swamps, and damp pinelands, but less often in pocosins and streamheads, though it can be found in most any kind of wetland habitat. It does occur into more mesic pinelands, and in the Piedmont it seems most numerous in pine stands, especially in Loblolly Pine (Pinus taeda) stands.
PhenologyFlowers mainly in April, and fruits from August to October.
IdentificationThis is a tall shrub, often considered as a small tree as well, ranging to about 12-20’ high – the tallest of the Morella species. It has alternate, evergreen leaves that are narrowly lanceolate, with a few sharp teeth toward the tip, as do other Morella species. It can be separated from both Morella caroliniensis and M. pensylvanica by its thinner and narrower leaves; they are about 2.5-3” long, but always less than an inch wide, more often about 2/3” wide. The twigs tend to be light gray, paler than in the other two; and the fruits are also smaller. Normally, this shrub is easy to identify, as it is so abundant in coastal areas and present at sites where the other two are not found (such as tidal areas south of Dare County). But, care must be taken in coastal Dare County, with M. pensylvanica, and in freshwater wetlands, with M. caroliniensis.
Taxonomic CommentsAll Morella species were, until recently, included in the genus Myrica – i.e., Myrica cerifera. RAB (1968) and some other references have the species split into the nominate var. cerifera and the small-stature form – var. pumila. Some references do not have these forms broken out at all, whereas Weakley (2018), this website, and perhaps a few others have these forms split as separate species.

Other Common Name(s)The species is usually simply called Waxmyrtle. However, with the elevating of Morella pumila to full species status by some entities, including here, it is best (and proper) to give a modifier name to M. cerifera – in this case Common Waxmyrtle – to avoid confusion. Other names include Southern Bayberry (confusing, with M. caroliniensis also called this), Candleberry, Bayberry-tree, Tallow-shrub
