Globe thistle is a tough, low-maintenance perennial that thrives in well-drained soil and full to partial sun. Water deeply but allow the soil to dry out between waterings, as it is quite drought-tolerant once established. It makes a stunning border plant and the striking blue spherical blooms are beloved by pollinators.
