Forming slightly flattened, round stems with a dusty green base hue, P. graessneri Golden Donut earns its name from the colorful patterning of its spines and areoles. Clustering around the depressed apex of the plant which resembles the depression in the center of a donut the warm yellow spines create the appearance of a dusting of yellow glaze. The resemblance behind “golden donuts” namesake is further enhanced by the buttery yellow summer blooms, which will emerge from the uppermost portion of the stem each year.

A relatively hardy specimen,it prefers plenty of bright yet indirect light though it can also tolerate full sun during the morning hours. Like all cacti, it can be prone to rot when subjected to excess moisture. To avoid this fate, be sure to adhere to a thorough yet infrequent watering routine, coupled with a porous soil mixture within a well-draining pot. Ample airflow around the stem and soil surface will provide further insurance against dampness, helping to evaporate moisture trapped within the clusters of spines.

Hardy only to Zone 10, be sure to shieldit from freezing temperatures during the winter months, to avoid permanent scarring to the compact stem.
