Frequently Asked Questions: Flowering Kale vs Ornamental Cabbage
What is the difference between flowering kale and ornamental cabbage?
Flowering kale has open, ruffled, or fringed leaves that form a loose rosette. Ornamental cabbage forms a tight, rounded head that resembles a giant rose or cabbage. Both are Brassica oleracea cultivars, equally cold-hardy, and grown the same way from seed. The difference is purely aesthetic — leaf form and plant structure.
Are flowering kale and ornamental cabbage the same plant?
They are the same species (Brassica oleracea) but different cultivar groups. Flowering kale cultivars are selected for open, frilly foliage while ornamental cabbage cultivars are selected for tight, rounded heads. Both are grown as cool-season ornamentals for fall and winter color.
Which is more cold-hardy — flowering kale or ornamental cabbage?
Both are equally cold-hardy, tolerating temperatures down to 5–10°F in most varieties. Neither has a significant advantage in cold tolerance — choose based on aesthetics rather than hardiness.
Can you eat flowering kale and ornamental cabbage?
Both are technically edible but quite bitter and tough compared to edible varieties. They are primarily grown as ornamental plants. The leaves are safe to eat but most gardeners grow them purely for their visual impact in the fall garden.
Which is better for containers — flowering kale or ornamental cabbage?
Both work well in containers. Flowering kale varieties like Crane Pink add drama and texture. Ornamental cabbage varieties like Osaka Mix provide bold, structured color. For the most visually interesting container, combine both types.
When do flowering kale and ornamental cabbage reach peak color?
Both reach peak color after the first frost — typically when nighttime temperatures drop consistently below 50°F. The cold triggers the production of anthocyanins, the pigments responsible for the pink, red, and purple colors. The colder it gets (within their hardiness range), the more intense the color becomes.
What are the best flowering kale seeds to buy?
For home gardeners, the Crane series is the top choice for flowering kale seeds — large rosettes, excellent color, and outstanding cold tolerance. For ornamental cabbage, the Osaka series and Pigeon series are the most reliable performers.
