Portabella/ Crimini (Agaricus bisporus)

The reason we like the Heirloom Portabella is because it consistently grows large portabella size mushrooms with little to no effort. These mushrooms are thick and can often grow as large as the opening of the mushroom kit. The kit grows a higher percentage of the larger Portabellas than our standard Portabella/Crimini kit. It is amazing to see and taste the beautiful flesh of these giant mushrooms. It is truly one of our best mushroom kits.
