Ideal for garnishing salads, soups, pasta, and Mediterranean dishes, they add visual appeal and aromatic depth without the cooking time required for mature basil. Best grown in well-draining potting mix under full sun to partial shade (4-6+ hours daily).

Buckwheat Microgreens
Buckwheat is widely grown as a grain crop, bee pasture, soil improving cover crop and as wildlife cover. It is a warm season grain which grows rapidly during the summer and several crops per year may be had with proper management. This rapid and dense growth chokes out weeds and is used in crop-free fields in rotation with vegetables. Buckwheat is often grown to attract beneficial insects and as pasture for honey bees. Sow in late May through July and till in about a month later, when flowering has begun. For grain harvest, sow 3 months before fall frost. Harvest after killing frost.
Cabbage Microgreens
Cabbage Microgreens are tender, delicate seedlings harvested at 7-14 days, well before the 68-day full plant maturity. These vibrant green microgreens feature a mild cabbage taste with a fresh, crisp texture and subtle peppery finish. They're prized for their nutrient density and visual appeal in salads, garnishes, and culinary presentations. Easy to grow indoors using fine potting mix or coconut coir, they require 4-6+ hours of light daily.

These heirloom microgreens deliver an intensely concentrated cilantro flavor—bright, citrusy, and distinctly herbaceous—making them a potent garnish and flavoring agent. Ideal for fresh applications like salsas, Asian cuisines, and contemporary plating, they add sophisticated herb character to dishes without bulk. Their moderate difficulty and preference for well-draining medium make them suitable for home cultivation under full sun to partial shade conditions.
Clover Microgreens
Once established, white clover can handle foot and tractor traffic better than other clovers. The fibrous root system typically is in the top 8" of soil, although it does have up to a 40" tap root in the first year which dies each fall, leaving a passage for water to percolate through. More heat tolerant than some of the larger clovers, this is a low-growing (to 12") perennial that can be sown into long-season row crops during the season to provide a "living mulch." Sow after first cultivation and rake or cultivate to cover. Also used for green manure, hay, and pasture. Inoculate with Alfalfa/True Clover Inoculant (#7535) for best performance.

Moderate to advanced difficulty level due to moisture management requirements and susceptibility to aphids and spider mites in dry conditions.
Lettuce Microgreens
Lettuce microgreens are tender seedlings harvested at 1-2 inches tall, typically ready within 7-10 days of sprouting. These delicate greens feature soft, pale green leaves with a mild, slightly sweet flavor and buttery texture—distinctly different from mature lettuce. Unlike full-sized lettuce, microgreens are consumed whole, including the stem, delivering concentrated nutrients in a compact form. They excel as salad toppings, sandwich garnishes, and plate decorations, adding visual appeal and gentle flavor without bitterness.
