Plants

Black Needlerush

Juncus roemerianus

Range/Geographical Distribution: Along the coast from Delaware to Texas.

Habitat: Salt and brackish water marshes in the high marsh. 

Description: Leaves are black/gray/green and stem-like, with very sharp points.  Occurs in dense stands. 

Size: Can reach five feet in height.

Breeding: Flowers from May to October and produces tiny, dark seeds from July to November.

Predators/Ecological Function: Large, dense, areas of black needlerush protect shorelines, help filter suspended solids, take up nutrients, and facilitate soil oxygenation. Birds and muskrats use the seeds and vegetation of needlerush.

Conservation Status: No legal status.

Interesting Facts: Black needlerush is one of more than 30 rushes that can be found in Georgia.  This rush is often used to help restore estuaries. 

On the Coast: Black needlerush is a dominate plant of the saltmarsh and can cover large areas in the high marsh along Georgia’s coast.  Be careful when walking through these areas as the sharp leaves of this plant can cause injuries.

Cabbage Palm

Sabal palmetto

Range/Geographical Distribution: Along the coast from North Carolina to Louisiana, also in the Bahamas and Cuba.

Habitat: Freshwater swamps, low coastal areas, hammocks, pine forests, and hardwood forests. 

Description: A solitary palm with a single trunk and a canopy of 24-36 leaves that can reach over six feet in length and three feet in width.

Size: Can grow to 80 feet in height.

Reproduction: Flowers spring to fall. Produces green fruits called drupes that are about a half inch in diameter and turn black when mature.  Seeds germinate in two to three months.

Predators/Ecological Function: The small fruits are eaten by birds, squirrels, bears, raccoons, and deer.  The flowers provide nectar for butterflies and birds use the leaf fibers for building nests.  Epiphytes grow on the trunk or the base of the leaves and frogs and bats use the leaves for shelter.

Conservation Status: No legal status.

Interesting Facts: The cabbage palm is the state tree of Florida and South Carolina.  It is cold hardy to at least 15˚F.  Cabbage palm leaves were used by indigenous people to make nets, baskets, and thatch.  Seminoles used the trucks for poles, paddles, arrows, and more.  People still cook and eat the terminal bud or “cabbage” of the palm, calling it heart of palm.  Eating the bud kills the palm. 

On the Coast: Cabbage palms are common along the Georgia coast and are highly hurricane and fire resistant.

Live Oak

Quercus virginiana

Range/Geographical Distribution: Along the coast from Virginia to Mexico.

Habitat: Woodlands, sand ridges, maritime forests, and other dry areas along the southeastern coast. 

Description: Short, thick trunk that is divided into many branches. Gray bark is deeply divided into furrows and becomes blocky with age.  Leathery, green, oval leaves are pale gray/green below and can reach five inches in length.

Size: Can grow to more than 60 feet tall and have a limb spread of 80 feet.

Breeding: Produces acorns in the fall, some years copiously and some years none at all.  Acorn caps cover about 1/3 of the nut and acorns are grouped in clusters of two to five.

Predators/Ecological Function: Epiphytes such as Spanish moss, resurrection fern, and ball moss are common along the branches of live oaks.  Birds, bear, deer, and squirrels eat the acorns.

Conservation Status: No legal status.

Interesting Facts: The live oak retains its old leaves until new ones appear and is thus considered “evergreen”. 

On the Coast: Live oaks are one of the most recognizable trees of the south and are common all along Georgia’s coast.

Longleaf Pine

Pinus palustris

Range/Geographical Distribution: Along the coastal plain from Virginia to Texas.

Habitat: Well-drained, sandy areas with other trees including oak, dogwood, blackgum, sweetgum, persimmon, and sassafras. 

Description: An evergreen conifer with scaly bark and 8-18 inch needles. 

Size: A mature tree may reach a height of 100 to 120 feet.

Breeding: Begins to reproduce at 30 years of age and 10 inches in diameter. The six to eight inch cones usually contain about 35 winged seeds.   The seeds germinate in one to two weeks, seedlings are initially stem-less, and production of branches occurs after the seeding reaches at least ten feet in height.

Predators/Ecological Function: Longleaf pine forests are a habitat for many bird species as well as deer, gopher tortoises, and squirrels.  Birds and small mammals eat the pine seeds and old pine trees provide a nesting habitat for the endangered red-cockaded woodpecker.

Conservation Status: The longleaf pine is not an endangered species but many endangered plant and animal species can be found in longleaf pine communities.  In Texas, these communities are considered threatened by the Texas Natural Heritage Program.  It is estimated that longleaf communities once covered 90 million acres but now only cover 5-10 million acres in the United States.

Interesting Facts: Longleaf pines can hybridize with the loblolly pine and the slash pine.  These trees may live four or five centuries. The longleaf pine is fire-resistant and fires help reduce competition from other trees as well as help seeds germinate by exposing the soil. 

On the Coast: Current longleaf pine communities are mostly found on private hunting plantations and military land although this type of forest was the dominant woodland in coastal Georgia before European settlement

Perennial Glasswort

Salicornia virginica

Range/Geographical Distribution: Along the coast from Nova Scotia to Florida and Texas as well as from Alaska to Mexico.  Also found in India, Japan, Korea, Russia, SW Asia, and Europe.

Conservation Status: No legal status.

Interesting Facts: Dried, ripe fruits are processed into a drug called serenoa that is used to treat bladder, prostate, and urethra infections. 

On the Coast: Large clumps of saw palmettos may be seen within coastal Georgia’s forests and barrier islands.

Sea Lettuce

Ulva lactuca

Range/Geographical Distribution: Worldwide.

Habitat: Attached to hard surfaces along shores in brackish water and estuaries, also may be found as a free-floating mass in sheltered waters.

Description: A bright green algae with broad, crumpled, translucent fronds.   Resembles terrestrial lettuce, hence its name.

Size: Clumps may reach a foot in diameter.

Breeding: Adult plants produce zoospores that settle and form haploid male and female plants similar to the adults. These haploid males and females release gametes.  The gametes combine and produce a zygote which grows into an adult plant.
