Bathurst Aster Photo 1



The Bathurst Aster is an annual plant which measures about 20 cm in height. It seems squat because of the numerous branches at the base of the plant. The leaves have rounded tips; the flowers are white.


Distribution and Population

The Bathurst Aster is found only in New Brunswick.



The Bathurst Aster grows in areas where salt water is present; it is found in salt marshes or in saline sands and gravel that occur at or just below sea level.



The Bathurst Aster flowers in late August and early September. This plant reproduces through seeds.



It is believed that loss of habitat is responsible for the fact that few populations of Bathurst Aster exist in Canada. Pollution and disturbance of sites due to development could threaten the remaining populations of Bathurst aster.
