Purple Cauliflower

Purple Cauliflower in 4-Inch and 6-Inch Pots available in Jupiter, FL

Bold, beautiful, and nutrient-packed—Purple Cauliflower (Brassica oleracea var. botrytis) is the showstopper of the winter garden. With striking violet heads and tender florets, this unique cauliflower not only adds color to your plate but also delivers a mild, sweet flavor that’s less bitter than traditional white varieties. Plus, the purple hue comes from natural antioxidants—making it as healthy as it is eye-catching.

These 4-inch and 6-inch pots offer a strong head start for South Florida’s cool-season planting window.

Care & Growing Info (Optimized for South Florida):

• Sunlight: Full sun (6–8 hours daily) is best for tight, vibrant heads.

• Watering: Keep soil consistently moist but well-drained. Mulch helps maintain moisture and regulate temperature.

• Soil: Rich, fertile soil with good drainage and high organic matter. Compost-boosted soil is ideal.

• Fertilizer: Heavy feeder. Use a nitrogen-rich fertilizer early, then switch to balanced or phosphorus-boosting fertilizer during head formation.

• Growth Habit: Upright with broad leaves and central purple head. In pots, plants reach 10–14 inches tall before maturing to full size in the ground.

• Temperature: Thrives in 50–75°F. Best planted October through February in South Florida.

• Maintenance: Moderate. Keep pests like aphids or cabbage loopers in check. Blanching not needed—color stays vivid on its own.

The foliage is lush and broad, while the purple head is dense and ornamental. Harvest when heads are firm and 6–8 inches across, typically 60–80 days from transplant.
