Echinofossulocactus spinosus is a rippled cactus from Mexico. It has white spines and yellow flowers when in bloom. We recommend potting this slow growing plant in our well draining cactus mix and giving it 3-6 hours of direct sunlight a day. Cacti like to dry out for extended periods of time so we recommend a calendar to keep track of watering. We recommend watering every 3-4 weeks during summer and every 6-7 weeks during winter. A great plant for beginning collectors.
