Overview
A cold-season stunner that produces rosettes of ruffled or fringed leaves in vivid purples, pinks, whites, and greens that intensify as temperatures drop. Ornamental kale is technically edible but is grown primarily for its spectacular color, which peaks in fall and persists through winter. It is one of the few plants that actually gets more beautiful as the weather turns cold.
How to Grow Ornamental kale
Plant it in rich, moist, well-drained soil, at a slightly acidic pH of 6–7.5.
Exact sowing, transplanting, and harvest months shift by climate zone — the planting calendar below lays them out for cool through hot regions. Match it to the right spot, and the rest is mostly patience.
Companion Planting & Soil
Ornamental kale grows well alongside pansy, snapdragon, aster, and mum.
