Osaka Series Flowering Cabbage is a hybrid that transforms the humble cabbage into living ornament. These cool-season annuals grow to a compact 11-12 inches tall and mature in 90-99 days, producing tight, showy rosettes in striking pink, red, or white. Hardy from zones 3-11, they thrive in full sun and bring an unexpected elegance to any garden that can offer them cool weather. The 'flowering' cabbage appearance comes from their tight, ruffled leaf formation that resembles an intricate bloom rather than a traditional head.

The Osaka Series creates a visual spectacle that straddles the line between vegetable and ornamental. Its compact, mounding habit and jewel-toned foliage in pink, red, or white make it as striking in a flower bed as it is in a cool-season kitchen garden. The tight, flowery rosette form distinguishes it from conventional heading cabbages, giving gardeners an unexpected and sophisticated harvest from a plant that looks too beautiful to eat.
Osaka flowering cabbages are grown primarily for their dramatic visual appeal in cool-season gardens, though the leaves remain edible. The tightly formed, ornamental rosettes make them as suitable for display in a decorative border or as a focal point in a container garden as they are for harvest. When used in the kitchen, the tender inner leaves can be prepared like any cabbage, though many growers prize them more for their striking appearance in fresh arrangements and garden photography.
No timeline data available yet for this variety.
Start seeds indoors 4-6 weeks before transplanting to take advantage of cool spring weather, or time plantings for fall harvest 10-12 weeks before first frost.
Transplant seedlings outdoors once they have developed true leaves and soil conditions favor cool-season growth. Space plants 24 inches apart in rows or beds. Harden off seedlings gradually before moving them to full-sun garden locations.
Harvest Osaka flowering cabbages when the rosette has tightened into a compact, dense mound with fully colored leaves (pink, red, or white depending on variety). This typically occurs around 90-99 days after planting. Cut the entire head at the base using a sharp knife when the formation feels firm to gentle pressure. The tight, ornamental appearance itself signals readiness; avoid waiting too long into warm weather, as heat encourages bolting and opens the tight rosette.
