Introducing the Notocactus graessneri flaviflorus, which is a medium-sized solitary cactus that closely resembles the Parodia haselbergii. Native to southern Brazil, it is sometimes mistakenly called golden ball cactus, Yellow-Flowered Parodia, and Lemon Ball Cactus.
The Notocactus features a spherical shape with a greenish-yellow body covered in numerous small, golden spines. It thrives in the arid regions of these countries, where it has adapted to survive in dry and desert-like conditions.
The Notocactus graessneri flaviflorus has a compact size, typically reaching a height of about 4 inches and a diameter of about 6 inches. Its unique appearance makes it a standout addition to any cactus collection.
Its compact size makes it suitable for both indoor and outdoor cultivation. The flowers of Notocactus graessneri flaviflorus bloom during the late winter to early spring, with small yellow flowers lasting one to three weeks.
The petals spread upward, allowing stamens to be visible. The flowers grow as tubes with bristles and wool clusters.
When it comes to care, it requires well-draining soil and bright, indirect sunlight to thrive. Water sparingly, allowing the soil to dry out completely between waterings to prevent root rot. Additionally, provide occasional fertilization during the active growing season to promote healthy growth.
When growing indoors, your Notocactus graessneri flaviflorus prefers temperatures between 65-80°F. For outdoor cultivation, it is typically well-suited in USDA zones 9-11. It is important to protect it from frost and cold temperatures to ensure its growth and development.
To propagate the Golden Ball Cactus, you can use various methods such as seed propagation, offsets, or stem cuttings. Seeds can be sown in well-draining cactus soil and kept in warm and bright conditions. Offsets, also known as "pups," can be carefully separated from the mother plant and replanted. Stem cuttings can be taken and left to callus before planting in a suitable cactus mix.
Overall, the Notocactus graessneri flaviflorus is a unique and beautiful species of cactus that is sure to add a pop of color to any succulent collection. Its vibrant yellow flowers make it a standout choice for both experienced and novice plant enthusiasts.
