Black Pearl King Oyster (Pleurotus ostreatus × eryngii) is a rewarding variety to grow in your Flush. A chef’s favourite: dark caps and deep umami.
What to expect
A steady climate and a little patience will give Black Pearl King Oyster the best chance to fruit evenly. Check your block regularly as pins form and the first flush develops.
Growing in your Flush
