This extra-early purple cauliflower stands out with its striking violet heads that develop in nearly half the time of standard varieties. Growing as a compact 4-12 inch bush, Amethyst fits beautifully into smaller garden spaces while delivering full-sized flavor and nutrition. The dramatic color contrast makes it a showstopper in salads and side dishes, offering all the health benefits of traditional cauliflower with added visual appeal. Its reliability across a wide range of zones and low water requirements make it particularly valuable for gardeners dealing with challenging growing conditions.
Amethyst cauliflower excels in applications where its stunning purple color can shine, particularly in fresh salads where it provides dramatic visual contrast alongside other vegetables. Like traditional cauliflower, it can be steamed and mashed as a low-calorie, low-carb substitute for mashed potatoes, though its purple hue adds an unexpected twist to this classic preparation. The compact heads are perfect for roasting, pickling, or freezing after blanching, maintaining their nutritional density as an excellent source of vitamin C, vitamin K, and folate.
No timeline data available yet for this variety.
Start seeds indoors 4-6 weeks before your anticipated transplant date. Keep soil at least 70°F until germination, then maintain 60°F thereafter. Sow in 72-cell plug flats for best results.
Transplant seedlings when no older than 4-5 weeks old, as older plants tend to be stressed and perform poorly. Harden plants carefully by gradually increasing cold exposure before transplanting out. Space 18 inches between plants with 24-36 inches between rows.
Direct seed April through June, placing seeds at the bottom of the furrow and covering with loose soil or sifted compost. Not recommended for fall plantings.
Harvest when heads are tight and dense, typically 6-8 inches in diameter, using a clean, sharp knife while keeping some leaves around the head for protection. Remove heads that have started to open even if they seem too small, as overmature florets begin to separate and appear ricey. Heads with a coarse appearance should be discarded rather than harvested.
