Growing Non-GMO Purple of Sicily Cauliflower Vegetable Seeds

To grow Purple of Sicily cauliflower from seed, start by sowing the seeds indoors 4-6 weeks before your last expected frost date. Cauliflower can be directly sown outdoors with some protection by using a cold frame, winter grow tent, or garden cloche. Sow seeds about 0.25 inch deep in a seed-starting mix, making sure the soil is kept consistently moist but not waterlogged. The seeds should germinate within 7-14 days if kept in an environment of about 65-70 F. Once the seedlings have two sets of true leaves, you can begin hardening them off by gradually exposing them to outdoor conditions for a week before transplanting them into the garden.

When transplanting, choose a location that receives full sun, with rich, well-draining soil. Cauliflower thrives in fertile soil with a slightly acidic to neutral pH (6.0-7.5). Amend the soil with compost or well-rotted manure before planting. Space the plants 18-24 inches apart, with rows 24-30 inches apart. Mulch around the plants to help retain moisture and keep weeds down. Keep the soil evenly moist throughout the growing season, as cauliflower is sensitive to drought and inconsistent watering.

Throughout its growth, ensure that Purple of Sicily cauliflower is not exposed to temperatures that are too hot, as it prefers cooler weather between 60-70 F. Fertilize with a balanced fertilizer or one high in nitrogen, especially during the early growing stages to promote leafy growth. As the head forms, you can protect it by gathering the leaves loosely over it to shield it from direct sunlight, though this variety is more resistant to discoloration than white cauliflower varieties.

Its large, leafy canopy can provide ground cover and help suppress weeds, indirectly benefiting the garden. It is also often used in edible landscaping. Overall, it plays a decorative and edible role in home and commercial gardens.

Harvesting Purple of Sicily Cauliflower

Purple of Sicily cauliflower is ready to harvest when the heads are fully formed but still tight and compact. The heads should be 6-8 inches in diameter.

About Purple of Sicily Cauliflower Garden Seeds

This cauliflower’s striking purple color sets it apart from traditional white cauliflower, and it’s known for being rich in anthocyanins, which are antioxidants that provide health benefits and vibrant pigmentation.

It is native to the Mediterranean region, where it has been cultivated for centuries.

Purple of Sicily is most commonly grown in the fall or early spring, as cauliflower can suffer in hot weather. In warmer climates, providing some shade during the hottest part of the day may be necessary.

Tips From Our Gardeners

"Avoid planting cauliflower in the same area where other brassicas (such as broccoli or cabbage) have recently been grown. Crop rotation is an important practice for maintaining healthy cauliflower plants and reducing pest and disease pressure."
