55–60 days. Amethyst is as delicious as it is beautiful—truly the prettiest edible 'flower' in the garden. This vibrant purple cauliflower has a soft amethyst hue that sets it apart, coloring up and maturing earlier than our other purple varieties. The plants have an open habit and produce dense, tasty, 6–7 inch dome-shaped heads on sturdy, reliable stems. A great option for both summer and fall harvests, Amethyst is also perfect for succession planting. Include this early-maturing variety with our later purple types to extend your season and keep the colorful curds coming.
