The swamp starflower occurs in the Kenwick area of Perth. Historically, the species was also known from Gosnells and Bellevue, but it is now extinct in these areas. The species is restricted to winter-wet clay flats with low shrubs or jarrah forest. Germination is likely to be stimulated by fire or smoke, however, germination has also been observed in the absence of disturbance. The subspecies C. b. subsp. stipulosa occurs in a band extending from the northern jarrah forest, through the Wheatbelt to Esperance.
