Our Mushroom Selection
Pioppino
Nutty, crunchy stems that stay firm through any cooking method. Popular in Italian cuisine and gaining traction with chefs who want texture that doesn’t go mushy. Longer grow cycle, exceptional shelf life.
Enoki
Thin, noodle-like stems with tiny caps. Mild, slightly fruity flavor and a snap that holds up raw in salads or added last-minute to hot soups. Grows cold — fruits best below 60°F.
Oyster
Available in blue, pink, golden, and king varieties — each with its own flavor and texture. Fast-growing, beginner-friendly, and endlessly adaptable in the kitchen. The gateway mushroom for most home growers.
Reishi
Grown for medicine, not meals. Bitter and woody, traditionally prepared as tea or dual-extracted tincture. One of the most researched medicinal mushrooms, valued for immune support and stress adaptation.
Shiitake
Rich, smoky, deeply savory. A staple in Asian cuisine for centuries and one of the most studied mushrooms for health benefits. Slower to fruit than oysters but worth the wait.
Maitake
Large, feathery clusters with a rich, earthy flavor and meaty texture. Known as “Hen of the Woods” for its layered appearance. Excellent sautéed, roasted, or in soups. Valued both as a gourmet ingredient and for immune-supporting beta-glucans.
Lion's Mane
Seafood texture — often compared to crab or lobster. Increasingly popular for cognitive support, with research linking it to nerve growth factor production. Delicate to grow, stunning when it fruits.
Portabella
Mature cremini grown out to full size. Dense, meaty caps that hold up on the grill or stuffed and baked. Mild, earthy flavor that absorbs marinades like a sponge. A backyard BBQ staple.Shop
