Kohlrabi Konstance F1
2025 Edible - Vegetable
Kohlrabi Konstance F1

Praise for Konstance! She holds steadfastly in the garden to give a longer harvest window for kohlrabi fans. This new purple kohlrabi has an improved smoother skin and an attractive, vibrant purple color that extends out through the leaf margins. No matter if you grow in spring or fall, Konstance continues to produce flavorful crunchy bulbs that are crack-resistant and long-lasting. A bonus to the crisp, sweet, peppery bulb is that the leaves are also highly flavorful when roasted or sauteed, or eat them raw when the leaves are young and tender.

Judges Observations
  • “Good shape & color, good flavor and crunchy flesh.”
  • “Plants have continued to hold better in the field. Plants are much more enjoyable to look at than comparisons. We’re giving some bonus points for holding eating quality longer than comparisons. There is something to be said about this for the home gardener and getting longevity out of your investment.”
  • “This trial entry really pulled ahead if the comparisons in terms of its flavor and performance in the fall when our temps have not cooled down significantly. This was a winner this fall as it produced comparable bulbs to the spring, unlike the comparisons.”
  • “This entry impressed me against the comparisons, having significantly more uniform, rounded, crack resistant fruit. I preferred the flavor and texture of the entry over both comparisons.”
