Flower profile

Use cool weather to finish tall colorful rosettes.

Condor ornamental kale is bred for upright cut stems topped by ruffled rosettes. Plants grow through mild conditions, then develop their strongest white or red centers as nights cool.

Heat delays colorSchedule plants so rosettes mature as temperatures fall. Warm weather keeps centers green and can stretch or weaken young plants.
