First up each spring are fresh "Orchard" morels from the West coast. Called "orchard" morels because they pop up in the orchards and meadows of Northern California these wild morels are delicious and flavorful and run 1 - 3 inches in size.
Later in mid-spring (late April - May), "dark morels", which grow throughout the Midwestern states. They are typically anywhere between 1 and 4 inches in size and have a deep, intense morel flavor.
For a few weeks in May, the larger, beautiful "blonde morels" are available. Blonde morels are usually a bit larger than the other morel varieties and have a milder flavor. The season is shorter, the supply smaller, and the demand is higher for these prized mushrooms.
