Morphological Characteristics

  • A small tree with a spreading open crown, reaching 6 to 8 feet in height.
  • Forms dense thickets.
  • Seeds are variable in color (red/brown), 2-4mm in length, smooth, and cordate (heart-shaped).

Distribution and Habitat

  • Found in pinelands, beach dunes, and coastal thickets.
  • Grows in moist, well-drained sandy or limestone soils.
  • Specific location mentions include the Monroe County Keys.

Ecological Role

  • This species can self-seed rampantly and forms large thickets.
  • Other species with the common name "Rattlebox," such as Sesbania punicea (Spanish Gold, Scarlet Sesban), are known to displace native vegetation and wildlife by forming dense thickets, especially in damp areas and along river banks. These species can be invasive.
