25+ Flowering Kale Ornamental Cabbage Seed Mix - Pink, Red and White

Flowering Kale Ornamental Cabbage Seed Mix – Pink, Red and White (Brassica oleracea) produces compact, flower-like rosettes with colorful centers in shades of pink, red, and creamy white, surrounded by contrasting green foliage. These plants are grown for their decorative leaves rather than their flowers. Ornamental kale varieties generally have curled or deeply cut leaves, while ornamental cabbage varieties have broader, smoother leaves. Their colors become richer and more vibrant as temperatures cool, making this mix perfect for autumn and winter flower beds, borders, containers, window boxes, and seasonal displays. Mature plants commonly grow approximately 12–15 inches tall and wide.

Planting Season

Best planted in: Summer for Fall & Winter Color (Cool-Season Ornamental)

Start seeds approximately 8–12 weeks before the first expected autumn frost or the desired display date. In mild-winter climates, seeds may also be started in late summer for winter displays.

Young plants are mostly green during warm weather. Pink, red, and white pigments become more noticeable when temperatures fall below approximately 60°F (16°C), with the most vivid colors developing below 50°F (10°C) and after exposure to light frost.

How to Grow Flowering Kale Ornamental Cabbage Seeds

Start seeds indoors in trays, individual cells, or small pots. Seeds may also be sown in an outdoor nursery bed if temperatures remain cool.

Choose a location with full sun for compact plants and the brightest foliage colors. Provide light afternoon shade while seedlings are young if summer temperatures are very hot.

Grow in fertile, moderately moist, well-drained soil enriched with compost or well-rotted organic matter.

Press seeds onto the surface of a moist seed-starting mix and cover them only very lightly with fine vermiculite. Do not bury the seeds deeply because light helps support germination.

Sow 1–2 seeds per cell and thin to the strongest seedling after emergence.

Keep the growing medium consistently moist but never waterlogged.

Maintain temperatures around 65–70°F (18–21°C) during germination. Avoid excessive heat, which can cause weak, stretched seedlings.

Seeds typically germinate within approximately 3–10 days under suitable conditions.

Provide bright light immediately after seedlings emerge.

Transplant seedlings after they develop several true leaves and temperatures begin to cool.

Harden seedlings gradually for 7–10 days before transplanting them into their permanent location.

Space plants approximately 12–18 inches apart, depending on the desired mature size. Plant the stems deeply enough that the lowest leaves are close to the soil surface, while keeping the central growing point above the soil.

How to Care for Flowering Kale Ornamental Cabbage Plants

Water regularly and keep the soil evenly moist throughout the growing season. Provide approximately 1 inch of water per week when rainfall is insufficient.

Water near the base of the plants and avoid allowing water to remain inside the central rosettes during cool, humid weather.

Amend the soil with compost or aged organic matter before transplanting.

Apply a balanced, slow-release fertilizer during early growth. Avoid excessive nitrogen once the plants become established, as it may encourage loose green growth and delay strong center coloration.

Mulch lightly around the plants to conserve moisture, regulate soil temperature, and suppress weeds. Keep mulch away from the central crown.

Remove weeds carefully to avoid disturbing the plants’ shallow roots.

Inspect plants regularly for aphids, slugs, cabbageworms, cabbage loopers, cutworms, flea beetles, and other common brassica pests.

Remove damaged or yellowing outer leaves to maintain clean, attractive rosettes.

Allow plants to remain outdoors during cool weather. Their foliage colors intensify after exposure to cold temperatures and light frost. Well-established plants can remain decorative through late fall or early winter, depending on the local climate.

Plants generally require approximately 10–14 weeks from sowing to develop mature, strongly colored ornamental rosettes.
