Echinopsis chamaecereus 'Rose Quartz' - Peanut Cactus hybrid
This cactus has stunning palm-sized flowers on columns with prickly spines. The flowers are irridescent pink with some orange tones. Each flower lasts for one day but more coming. The plant grows lots of segments and will form a clump, or you can remove and root segments to grow more plants.
