Chaetadelpha wheeleri forms a low bush with plentiful erect stems covered in very narrow, long and pointed leaves. Branchlets emerge from the stems and each bears a cylindrical flower which opens at the end into a star-shaped white or pale purple flower with five ray florets. The center of each head is filled with curly pollen-dusted anthers. This species is found most often in sand and scrub, particularly in desert regions.[6]
