When selecting the Druid class, the description on the far right show the orders. Flame is missing, but is listed as the header for the Stone order.
You’re as enduring as stone, and you take comfort in its steadfast presence, both natural and worked. You’re trained in Crafting. You also gain the Steadying Stone druid feat. You gain the crushing ground order spell. Poisoning or polluting the land and heedlessly carving the earth to plunder its natural resources are anathema to your order (this doesn’t prevent you from responsibly digging or mining).
