Grow your own mushrooms! The Pearl Oyster (Pleurotus ostreatus) A strain of oyster mushroom found in the forests of beautiful British Columbia  & named for their pearl colour. A delicious and wholesome food, oyster mushrooms are increasingly being used as meat replacements in vegetarian diets, and for the ecologically conscientious consumer. Our hardwood fruiting blocks are innoculated and allowed to partially myceliate prior to shipping. Watch as the mycelium cultivate your block, then slice open the wrap to allow the mushrooms to grow. Pick and eat as they develop. Delicious, succulent, and perfectly fresh.
