Red Cabbage microgreens produce some of the most visually spectacular cotyledons in the microgreen world. The deep purple-red coloration comes from high concentrations of anthocyanin pigments that are remarkably color-stable — they hold their vivid hue even after light blanching, mild acidity, or extended plating times. Flavor is mild, slightly sweet, with the familiar brassica undertone of their mature form. These properties make red cabbage the preferred choice where visual impact and color stability are paramount.
Brassica oleracea var. capitata f. rubra produces seeds that germinate uniformly within 2–3 days. The anthocyanin pigmentation is genetically determined and begins developing within the hypocotyl even during the blackout phase. Upon light exposure, the cotyledons develop their characteristic purple-red/violet coloration as anthocyanin synthesis accelerates in response to the light stimulus. The intensity of color can be modulated by growing temperature — cooler conditions produce more vivid pigmentation.

Red Cabbage microgreens are among the highest anthocyanin-containing foods in the fresh produce category. These pigments are responsible for both the vivid coloration and the significant health properties.
Red Cabbage microgreens serve a dual role as both a nutritional powerhouse and an irreplaceable visual element. Their color-stable pigmentation is unique — most purple-colored foods fade or discolor quickly.
