Turbinicarpus gielsdorfianus is a clustering plant formed by several, small, globose, blue-green bodies about 1-2 inches in diameter. The spines are white or black, or a combination of the two, and stand out against the bluish body. Small, butter-yellow flowers appear in summer. In habitat, plants are found growing on steep hills and mostly in cracks of limestone rock. Plants have proven hardy to at least 25 degrees F in Tucson.
