What is Palm Grass?

Palm Grass is a tropical plant that’s native to tropical and sub-tropical regions of Asia. This plant is part of the Poaceae family and has the botanical name Setaria palmifolia.

Palm grass is a perennial that has deeply pleated course leaves. Each leaf can grow very up to 13 feet long, with a width of 25 inches. The foliage grows from a central crown and forms a large mound.

Palm grass gets very tall in its native environment. When grown in cooler regions, its growth will be stunted, and the plant is likely to grow to about 3 feet. There are reports of palm grass growing to between 8 and 10 feet tall in areas such as Florida and Miami. Although palm grass looks robust, it’s pretty tender and can be affected by frost.

Palm Grass produces cylindrical flowers that are a light green color. The blooms appear in spikes that are taller than the rest of the foliage. These plants flower throughout the summer months, but the flowers aren’t very eye-catching or impressive.

Palm Grass isn’t toxic to humans, pets, or livestock. It can be grown as part of a flower border, a container, or a woodland garden. It’s worth noting that Palm Grass can quickly spread as its flowers self-sow and spreads many seeds. Some homeowners find that these plants start to take over and need to be controlled.
