Pediocactus simpsonii, Torrey, Utah Second watering of 2026 for my Pediocactus simpsonii . It is one of my favorite species. The many variations allow you to build a large collection without ever having two identical plants. It grows easily on its own roots and starts its growth in late February/early March in my Glâne region climate in the Canton of Fribourg, Switzerland. I took the opportunity to water them as about ten sunny days are forecast. The buds are swelling quickly
