Golden Ball
Parodia magnifica
"A blue-green globe pricked with gold"
Native to
Rocky slopes of southern Brazil and Uruguay

History
A brief account
A ribbed spherical cactus clothed in soft yellow spines, crowned in summer with sulphur-yellow flowers. Named for its truly magnificent form, it clusters slowly into cushions over many decades.
How to care for
Golden Ball (Parodia magnifica) grows best when its natural cycle of strong light, freely draining soil and measured watering is respected. Give it bright direct sun with a little afternoon shade. Water it according to its seasonal needs: moderate in summer; entirely dry in winter. Plant it in fast-draining cactus mix with extra grit. A container with an unobstructed drainage hole is essential, because moisture lingering around cactus roots can quickly lead to rot.
Keep its temperature needs in mind: 5–30°c. cool dry winter needed for flowering. During active growth, check the compost before watering rather than following a rigid calendar, since heat, light and pot size all change how quickly it dries. Reduce watering during cool or dormant periods, keep the plant well ventilated, and wait until the growing medium is dry before watering again.
How to propagate
Offsets divide readily. Separate established offsets during the warmer growing season, using clean tools and preserving any roots already attached. Allow damaged surfaces to callus before potting into a dry, mineral-rich mix, then water cautiously while the new root system establishes.
Young cacti are especially vulnerable to excess moisture. Use a small pot with excellent drainage, provide bright filtered light while roots establish, and move the new plant gradually into the light, temperature and watering conditions preferred by a mature Golden Ball.
