Ruby Perfection Cabbage (Brassica oleracea (Capitata Group) 'Ruby Perfection')
BRASS-ih-kah oh-ler-AY-see-ah (Capitata Group) 'Ruby Perfection'

Annual (usually grown as an annual near you) Rosette in the Brassicaceae Family
A uniform, dense red cabbage with deep purple-red heads -- a reliable keeper, excellent fresh or stored.

'Ruby Perfection' is an F1 hybrid red cabbage from the Capitata Group, prized as one of the most popular mid-to-late-season red cabbages for its uniform, dense, high-round heads of solid deep purple-red with good-quality wrapper leaves. It typically reaches harvest in about 85 days from transplant, with heads commonly weighing 4-6 pounds.

Beyond fresh eating, it's an excellent keeper -- properly stored heads can last well into late winter or early spring, making it a reliable choice for root-cellar storage as well as the kitchen.

Pros

  • Uniform, dense, high-round heads with excellent eating and storage quality
  • One of the most widely grown mid-late red cabbage varieties
  • Good keeper -- stored heads can last well into late winter or early spring

Cons

  • Needs cool weather for best head quality -- struggles and may bolt in summer heat
  • Susceptible to common cabbage pests like worms, loopers, and flea beetles, and to diseases like black rot in humid conditions
  • Takes a full season (about 85 days from transplant) to reach harvest size
Highlights One of the most widely grown mid-late red cabbage varieties, prized for its uniform, dense, high-round heads and excellent storage quality.

Field-Grown vs. Greenhouse-Grown Plants

Plants which are well-adapted to our local climate are most often field-grown (outside). Field-grown plants are generally cheaper and have the advantage of already somewhat acclimated to our cold winters, but that means they’re not artificially far along in the spring and tend to bloom at the normal time in our area.

Spring annuals and tender perennials are typically grown in Greenhouses so they can be ready and luxurious exactly when customers want them. Some perennials are also “forced” into early bloom in greenhouses. In May, there can be a very big difference between field-grown and greenhouse-grown plants of the same type. The latter typically look good right away (so they’re a great choice where that’s important), but we typically pay a premium for it.

No Pricing or Availability Right Now

We order from a rotating cast of the best nurseries in the Great Lakes region. It looks like we've offered this plant in the past, but the nurseries we're working with this week don't appear to have it in stock at the moment.

Our goal is to bring as many plants together under "one roof" as possible, so we'll try hard to make it available again in the future!
