1. It’s Not a Moss

Despite its name, Spanish moss is not a true moss. It is a flowering plant in the bromeliad family, making it a relative of the pineapple. Its technical name is Tillandsia usneoides1.

2. Spanish Moss is an Epiphyte

Spanish moss is an epiphyte, meaning it grows on other plants but does not parasitize them or take nutrients from them. It anchors to trees with tiny scales along its stems and leaves, absorbing water and minerals from the air and rainfall2.

3. It Grows Very Slowly

This air plant is exceptionally slow-growing, adding just a few centimeters in length each year. Thus, the long beards of moss seen hanging from tree limbs are often decades old. Their slow growth allows them to thrive even through storms and drought.

4. Spanish Moss Helps Its Ecosystem

This plant creates microhabitats for wildlife. Birds use it to build nests while three species of bats, including the endangered Seminole bat, roost in its tangles. It also shelters insects, spiders, tree frogs, lizards, and snakes.

5. It Has Air-Purifying Qualities

Spanish moss absorbs airborne particles along with moisture and nutrients. This makes it an excellent natural air filter. But pollution causes it to recede, so it can indicate environmental quality.

6. The Plant Has Medicinal Uses

Native Americans traditionally used Spanish moss to treat fever, chills, and rheumatism. Today, research shows extracts from the plant have antibacterial properties that help heal wounds and may also reduce blood sugar levels.

7. It Has Strong Cultural Ties

This plant is woven into southern heritage and lore. Its romantic, unkempt appearance has made it an icon of Southern Gothic literature and art. Spanish moss also holds spiritual meaning for groups like Louisiana’s Houma tribe.

8. People Once Used It Commercially

Early settlers and Native Americans wove the plant’s strong inner fibers into fabric. Later, it was harvested commercially for mattress and upholstery stuffing, shipped by the boxcar-full to factories. Though no longer used this way, Spanish moss still has many applications.

9. The Plant Has Versatile Uses

In addition to decor and crafts, Spanish moss has served as insulation, a tinder for fires, a pottery ingredient, and a thickener for plaster. Gardeners use it as mulch and its boiled “tea” makes an excellent natural fertilizer. It even helped make concrete-like tabby mortar used in Southern architecture.

10. There are Many Myths About It

Folklore often paints Spanish moss as a threat, but it’s mainly benign. Contrary to popular belief, it generally doesn’t host chiggers or harm trees. It likely doesn’t weigh down healthy branches, though it may indicate existing weakness by thriving on struggling trees.

11. Its Origins Are Mysterious

There are many tales about how Spanish moss got its name, but its origins remain uncertain. One story claims it resembled the long beards of Spanish conquistadors. Another legend says it was named by an American Indian who found the hairy clumps reminiscent of the Spaniard, Gorez Goz.

12. It’s Making a Comeback

Though Spanish moss declined in past decades due to pollution and overharvesting, conservation efforts seem to be reversing the trend and restoring this elegant plant to southern trees. Its re-emergence is helping revive both natural beauty and cultural heritage.
