Description of the Cabbage Palm
The Cabbage Palm is a tall, single-stemmed palm tree that can reach heights of up to 60 feet (18 meters) or more. Its trunk is stout and cylindrical, covered in old leaf bases that give it a unique and textured appearance. The crown of the tree is composed of large, fan-shaped leaves that resemble a cabbage head, hence its common name. Typically the lifespan of a Cabbage Palm is between 100 and 200 years.
Trunk and Foliage of the Cabbage Palm
The trunk of the Cabbage Palm is characterized by its robust and cylindrical shape. It is covered in persistent leaf bases that create a textured pattern. The deep green leaves of this palm type are fan-shaped and can grow to impressive lengths of 5 to 6 feet (1.5 to 1.8 meters).
Flowers & Fruits of the Cabbage Palm
During the summer, the Sabal Palm bears small creamy to white flowers that grow in clusters from within the crown. The flowers are held by 2ft long branches and are followed by a black fruit with a single seed inside. The Cabbage Palm fruit is edible.
Growth Habit of the Cabbage Palm
As a single-stemmed palm, the Cabbage Palm grows vertically, with its trunk gradually elongating over time. The growth rate of this palm tree is relatively quick, especially in its early years during which it can grow up to 2 inch per year. With proper care and favorable conditions, it can eventually reach its maximum height of 50 feet or more.
Cold Tolerance of the Cabbage Palm
The Cabbage Palm is one of the most cold-hardy palm trees, making it suitable for cultivation in various climates, including areas with mild to moderate winter temperatures.
