M. pumila, also known as Dwarf Wax-Myrtle, is a native perennial that varies in growth habit from an evergreen shrub and subshrub to tree growth. It is a member of the Myricaceae family, and can grow up to 6 feet high. The species is dioecious, with aromatic leaves and root nodules that help fix nitrogen in the soil. As well, it has rhizomatous roots which can propagate to form new growth.
M. pumila has staminate flowers with 3-5 stamens, fruit that are 2.0-3.5 mm in diameter, leaves that are serrate, oblanceolate, 0.5-1.5 cm wide and 4-6x as long. Its branches are 1.5-4 cm long and 3-8 mm wide.
Associated species - Vaccinium darrowi, Pityopsis spp.
Morella pumila is frequent and abundant in the Panhandle Silty Longleaf Woodlands and Central Florida Flatwoods/Prairies community types as described in Carr et al. (2010).
M. pumila flowers in April and fruits from August through October.
The species is mainly dispersed through animal consumption.
Seed bank and germination
The species requires a period of cold, moist stratification before germinating, where an average germination time is a month to 90 days. However, wax myrtles can also be propagated from semi-hardwood and soft cuttings treated with a rooting hormone.
Herbivory and toxicology
M. pumila is used by wild birds as a source of food, and the branches are also utilized by wild birds for nesting and perching habitat. It is a minor source of food for large mammals, water birds, and terrestrial birds, and a low source of food for small mammals.
Conservation, cultivation, and restoration
This Wax-Myrtle is popular for cultivation due to its ornamental value. M. pumila is also a good plant to use for native area restoration in its native communities like sandy coastal and woodland communities. It is a good plant for dune stabilization and further restoration.
