Sabal palmetto
Encyclopedia
Sabal palmetto, also known as cabbage palm, palmetto, cabbage palmetto, palmetto palm, blue palmetto, Carolina palmetto, common palmetto, swamp cabbage and sabal palm, is one of 15 species of palmetto
palm
(Arecaceae, genus Sabal). It is native to the southeastern United States
, Cuba
, and the Bahamas
. In the United States
it was originally found near the coast from St. Andrews Bay in the Florida
panhandle to the extreme southern coast of North Carolina
, and throughout most of the Florida peninsula. As a result of horticultural relocations, cabbage palms are now found throughout the south and mature plants are being grown in many areas not normally associated with palm trees. It is the state tree of both South Carolina
and Florida and is also the state symbol for South Carolina.
which extends as a center spine or midrib, (costa) 1/2 to 2/3 the length into a rounded, costapalmate fan of numerous leaflet
s. A costapalmate leaf has a definte costa (midrib) unlike the typical palmate or fan leaf, but the leaflets are arranged radially like in a palmate leaf. All costapalmate leaves are markedly recurved or arched backwards. Each leaf is 5 to 6.5 ft (1.5–2 m) long, with 40-60 leaflets up to 2.6 ft (80 cm) long.
The flower
s are yellowish-white, .20 in (5 mm) across, produced in large compound panicles up to 8.2 ft (2.5 m) long, extending out beyond the leaves. The fruit
is a black drupe
about 0.5 in (1.3 cm) long containing a single seed. It is extremely salt-tolerant
and is often seen growing near the Atlantic Ocean
coast.
For a palm tree, Sabal palmetto is very cold-hardy
--it is commonly accepted that Sabal palmetto is able to survive relatively short periods of temperatures as low as 7 °F (-13 °C). However, it has also been reported to survive temperatures much lower. Maintenance of the Cabbage Palm tree is very easy and very adaptable. The Cabbage Palm is known to tolerate drought, standing water and brackish water. Even though this palm is drought-tolerant, it thrives on regular light watering and regular feeding. It is highly tolerant of salt winds, but not saltwater flooding.
made a fort of palmetto trunks and from it defended successfully against the British in the Revolutionary War.
Sabal palmetto is a popular landscape plant known for its tolerance of salt spray and cold. Because of their relatively long establishment period and prevalence on ranchlands, few, if any are grown from seed in nurseries. Instead, established plants are dug in the wild with small rootballs since virtually all the severed roots die and must be replaced by new roots in the new location. Most leaves are removed at this time to reduce transpiration.
It is the state tree of South Carolina
and Florida
. Most references rate the species as hardy
to USDA hardiness zone 8a without protection, although with protection, proper siting, and care it can be grown in zone 7. Cabbage palms have good hurricane
resistance, but are frequently overpruned for a variety of reasons.
The growing heart of the new fronds, also known as the terminal bud, gives the tree its "cabbage" name, since this is extracted as a food and tastes like other undifferentiated plant meristem tissue, such as the heart of a cabbage or artichoke
. It is one of several palm species that is sometimes used to make heart of palm
salad. Heart of palm was commonly eaten by Aboriginal Americans
. However, extracting the heart will kill this species of palm, because the terminal bud is the only point from which the palm can grow and without this bud the palm will not be able to replace old leaves and will eventually die.
The cabbage palm is remarkably resistant to fire, floods, coastal conditions, cold, high winds and drought. Despite this, alarming causes of recent mortality include rising sea level (most noticed on the Big Bend Coast of Florida
), and Texas phoenix palm decline
(TPPD) a phytoplasma
currently found on the west coast of Florida.
Sabal palmetto trunks appear in two different conditions, which can be confusing (see photo). When leaves die, the leaf bases typically persist for a while, creating a spiky, "basketweave" effect. These remnant leaf bases are called "bootjacks" or "boots", for short. The name stems from the "Y" shape that was reminiscent of devices used to aid individuals in removing boots
. Transplanted palms are sometimes deliberately shorn of these bootjacks. Taller specimens are more likely to have lost their bootjacks and appear relatively smooth and columnar. The loss of bootjacks is a natural, if poorly understood, phenomenon as the palm does not create a leaf abscission
zone so the loss of the leaf bases results from some other physical or biological process.

Sabal 'Lisa'
Recently, a new mutant form of Sabal palmetto has been discovered in South West Florida, and named as a cultivar Sabal palmetto 'Lisa'. The difference between the 'Lisa' and the wild-type Sabal palmetto is in the form of the leaf. The 'Lisa' has leaves that are costapalmate, acute, not pendulous, not filamentose, rigid, not strongly divided, cupped, and slightly undulating. This mutation of Sabal palmetto is beginning to be seen in the nursery trade, as it is just as hardy to cold, salt, drought, fire and wind as the wild type of the species, but looks different. Two specimens can be seen in Fort Myers, FloridaFort Myers, Florida
