Cottony Golden Aster

Chrysopsis gossypina (Michx.) Ell.

Brief Summary

provided by EOL authors

The cottony goldenaster, Chrysopsis gossypina, is a member of the sunflower family (family Asteraceae).It occurs in the coastal plain of the southeastern United States, mostly along the Florida panhandle, but extending as far out as Louisiana to the west, and north to Virginia. It likes sandy soils, and grows in the harsh, sunny environments of coastal dune systems and nearby sandhills and scrub.

Cottony goldenasters are short-lived perennials, meaning that individual plants live for 2-3 years. They lose their leaves each winter, and grow anew in the spring from a ring of fuzzy leaves.Although they reach up to about 2.3 feet (70 cm) tall, their multiple stems often fall over as they grow so as larger plantsoccur as vine-like growth along the ground.In the fall, plants can produce up to 30 small, yellow, daisy-shaped flower heads (which are actually composites of multiple tiny individual flowers). The flowers grow so their heads are raised several inches off the sand.

Cottony goldenaster is quite variable over its range.This variability represents three subspecies of Chrysopsis gossypina that grow in mostly non-overlapping areas. The subspecies are primarily distinguished by the fuzziness of their leaves, differences in leaf shape, and mode of growth.

  • Chrysopsis gossypina subsp. cruiseana occurs on sand dunes on the coastline and barrier islands of the Florida panhandle and in Alabama. This subspecies, known as Cruise’s goldenaster, is rare and is classified as endangered/threatened by the state of Alabama.
  • Chrysopsis gossypina subsp. hyssopifolia occurs between Louisiana and Florida.It grows erect, as opposed to along the ground.
  • Chrysopsis gossypina subsp. gossypina is the most widely spread subspecies, occuring in open areas from Florida to Virginia.It is also the most variable in looks.Three different forms are identified, but a lot of intermediates between these forms also occur.

In the Florida panhandle, where these three subspecies overlap, they can hybridize with each other and also with the closely related C. godfreyi.This hybridization makes the identification of individuals a complex task.
