(Echinopsis) Our daughter Caitlin bought a little round cactus at the Herb & Flower Festival in 2013. She gave it a bigger pot and soon it was covered with baby cacti. Being quite the entrepreneur, she removed the biggest ones, potted them up, and is now offering them for sale. These cacti bloom once a year with a big white flower and produce numerous offspring. Grow cacti in well-drained soil and only water once a month. Drought-tolerant. Height: 4-6" Spread: 4" (Sun)
