The Shrubby False Buttonweed, also known as Whitehead Bloom, is native to the West Indies, Central America, and South America.  It was introduced into Florida and is considered a perennial weed. It is found along roadsides, open or disturbed sandy areas, and pinelands.

This plant grows to a height of 8-16 inches.  It has narrow lance-shaped leaves that average about 1-2 inches in length.  They have smooth edges with pointed tips and are oppositely attached to a thin upright stem.

The flowers are white and arranged in a compact cluster about 1/2-inch in diameter at the top of the stem.  A second cluster is sometimes found in the center of the next pair of leaves down the stem.  The cluster is wrapped around the stem.  These small white flowers bloom year round.  Many insects are attracted to these flowers, such as the Gray Hairstreak shown in the above photo.  All of the photos on this page were taken in Deep Creek in Charlotte County.
