Why Pearl Oysters?

Pearl Oysters (Pleurotus ostreatus) are one of the most beloved gourmet mushrooms. Their soft, ivory-white caps grow in cascading clusters that resemble delicate seashells giving them both elegance and charm.

When it comes to flavor, Pearl Oysters are mild, savory, and versatile. They have a delicate, earthy taste with a subtle seafood-like undertone, which makes them an excellent substitute for meat or shellfish in vegetarian dishes. When cooked, they develop a tender, slightly chewy texture perfect for stir-fries, soups, pastas, and risottos.

Pearl Oysters are also a reliable and forgiving variety, making them an excellent choice for beginners who want a plentiful and rewarding harvest.

Timeline and Growth Cycle of Pearl Oyster Mushrooms

1. Spore germination – begins at week 0.
2. Mycelium growth – colonizes rapidly, usually within 1–2 weeks.
3. Primordia (pinhead) formation – small clusters appear by days 7–10.
4. Young fruiting bodies – ivory-white caps begin forming around days 10–14.
5. Mature fruiting bodies – ready for harvest in as little as 14–18 days.
6. Spore release – occurs soon after caps fully open; harvest just before this point for the best flavor and shelf life.
