Stenocacti are among the early bloomers in my greenhouse. This S. coptogonus has not seen first watering yet, shivered after winter 'drought'. That of cause did not stop it from following the call of nature and celebrating spring with the crown of pretty flowers.
This young plant belongs to one of the long-spinned forms, and to stimulate the spines development is placed at the most sunny spot in the greenhouse. All Stenocacti a very heat and sun tolerant.
