King Oyster Grow Stick


King Oyster (Pleurotus eryngii)

The King Oyster is slightly more difficult to fruit than other oyster mushrooms as it does best in high humidity. Its lovely robust texture, delicious mild flavour, and longer shelf life make it well worth the effort. We suggest placing the grow stick in a Shotgun Fruiting Chamber for best results – here is a short How-To-Guide explaining how to make your own.

Use in a large variety of dishes or serve as “mushroom steaks”.


The King Oyster (Pleurotus eryngii) is a large, heavy mushroom with a substantial stem that is the star of the show. Their meaty texture is sometimes compared to abalone or scallops.

Unlike other oyster mushrooms, King Oysters have a long shelf life and can be kept in the fridge for up to two weeks after harvesting, especially if wrapped in tin foil.

With a mild flavour that is well suited to seasoning, this mushroom is very popular in the culinary world.
