Silver Ball Cactus
Parodia scopa
Silver Ball Cactus
Small, globose to 4″ diameter with dense spines. Can grow tall, to 20″! But generally they stay pretty short. Moderate clumping, yellow flowers. Hardy to 25F. From Rio Grande do Sul in Brazil.
It turns out the fruit is dehiscent. Nice to know! Not particularly unusual. But maybe you’ve learned a new word and concept today? Science!
