Nabalus racemosus, glaucous white lettuce, is a North American species associated with wet habitats such as streamsides, bogs, and moist parries.

Nabalus racemosus is a herbaceous plant that will be 30 to 175 centimeters (1 to 5.5 ft) tall when full grown.

[4][3] The leaves are hairless and glaucous, covered in natural waxes making them pale gray or blue-green.

It was found in every province from Newfoundland to British Columbia in Canada with the exception of Prince Edward Island.

[2] It is associated with water rich habitats such as stream banks, moist parries, alpine bogs, and wet meadows.

It is possibly locally extinct in British Columbia, Missouri, New Jersey, and Pennsylvania and likewise presumed extirpated from New York.
