Ornamental kale with vibrant purple rosettes – stunning cold-season plant and profitable cut flower for retail displays.

Ornamental Kale: Cold-Season Beauty and Profitable Retail Favorite

Why Ornamental Kale Stands Out

When most gardens begin to fade in the cold season, ornamental kale rises as one of the most striking and profitable plants to grow. With its ruffled leaves, bold colors, and unique textures, ornamental kale is a versatile crop for both landscapers and retailers. It thrives in cool temperatures, making it an excellent option for fall and winter displays.

Even better, some varieties of flowering kale are now in demand as cut flowers. Florists prize them for their long stems, rosette-like centers, and rich colors that resemble roses or peonies. Whether sold as potted plants in the retail market or bundled for floral arrangements, ornamental kale is a cold-weather powerhouse that earns its keep in every growing operation.

What Is Ornamental Kale?

Ornamental kale (often referred to as flowering kale) is a specially bred form of Brassica oleracea. Unlike edible kale grown for food, ornamental kale is grown for its decorative foliage. Its leaves form dense rosettes in shades of pink, purple, red, cream, and green.

As temperatures drop in autumn, colors intensify, creating dramatic displays that last well into winter. Hardy down to the mid-20s (°F), ornamental kale is a reliable performer when other bedding plants cannot withstand frost.

There are two main types:

  • Ornamental Kale for Bedding/Containers – Compact rosettes perfect for gallon pots, retail displays, and landscape use.

  • Cut Flower Kale – Tall-stemmed types grown for harvest, often reaching 24–36 inches with rose-like centers.

Why Ornamental Kale Is Perfect for Cold Season

Most crops struggle as frost approaches, but ornamental kale thrives in chilly conditions. In fact, cooler nights trigger its most vibrant color development. Retailers and gardeners love it because:

  1. Long-Lasting Displays – Ornamental kale can hold color and shape from October through December.

  2. High Retail Demand – With the right marketing, potted ornamental kale becomes a go-to fall and winter item alongside mums and pansies.

  3. Hardy and Low Maintenance – Requires little more than cool weather and even watering.

  4. Unique Aesthetic Appeal – Its leafy “flowers” set it apart from traditional blooms.

Ornamental Kale as a Retail Crop

Garden centers, nurseries, and box stores all rely on ornamental kale for fall and winter retail programs. Just like chrysanthemums, kale can be grown in gallon or larger containers for easy consumer appeal.

Key Retail Benefits:

  • High Profit Margins – Seeds are inexpensive compared to the retail value of a finished pot.

  • Cold Tolerance – Holds up during transportation and on retail benches when temperatures drop.

  • Visual Impact – Customers are drawn to bold textures and color contrasts.

  • Season Extension – Keeps retail shelves stocked after summer annuals fade.

Retail-ready ornamental kale in 6-inch or gallon pots is one of the easiest seasonal crops to produce and sell.

Ornamental Kale as a Cut Flower

While bedding varieties shine in containers, cut flower kale is rising in popularity among florists and growers. With proper spacing and cultivation, plants form tall, sturdy stems topped with rose-like rosettes. These “leaf roses” add incredible texture and novelty to fall and winter bouquets.

Why Florists Love Cut Flower Kale:

  • Long vase life (up to 2 weeks with proper hydration).

  • Pairs well with dahlias, chrysanthemums, sunflowers, and late-season grasses.

  • Unique colors like blush, burgundy, and creamy white.

  • Adds volume and structure to arrangements.

For farmers’ markets, weddings, or floral wholesalers, cut flower kale is an untapped niche crop that brings premium pricing.

Here’s a quick overview:

  1. Sowing – Start seeds indoors 6–8 weeks before transplanting. Use well-drained soil with pH 5.8–6.2.

  2. Germination – Kale germinates quickly, usually in 5–10 days at 65–70°F.

  3. Transplanting – Move seedlings to cell trays or directly into gallon pots once true leaves appear.

  4. Spacing for Cut Flowers – Space 6–12 inches apart for tall stems.

  5. Fertilization – Moderate feeding is recommended to encourage strong foliage growth without excess stretch.

  6. Cold Conditioning – Exposure to cool nights enhances leaf color.

With minimal input, ornamental kale is an easy crop for both small-scale gardeners and commercial growers.

Marketing Ornamental Kale

To maximize profits, growers should target both retail markets and floral design markets.

Retail Ideas:

  • Sell ornamental kale in mixed fall containers with pansies and ornamental grasses.

  • Market as a “frost-proof flower alternative.”

  • Use signage highlighting “Color That Lasts Through Frost.”

Cut Flower Sales:

  • Bundle stems for fall weddings and market bouquets.

  • Partner with local florists to supply wholesale bunches.

  • Market as “Rose-Like Kale Stems for Winter Arrangements.”

With the right strategy, ornamental kale bridges the gap between bedding plant sales and floral markets.

Sustainability and Resilience

Beyond its beauty, ornamental kale is also a sustainable crop:

  • Pest Resistant – While cabbage loopers may appear, damage is minimal compared to edible brassicas.

  • Low Water Needs – Requires regular moisture but not heavy irrigation.

  • Extended Shelf Life – Holds quality longer than many flowers or bedding plants.

Its combination of hardiness, beauty, and versatility makes it a sustainable profit driver for growers looking to expand into fall/winter crops.
