Amadeus delivers exceptional speed for a spring crop, maturing in under two months without sacrificing the quality expected from a Johnny's exclusive. The compact growth habit means it won't sprawl across your bed, making efficient use of space even in tight gardens. Its early maturity is the real advantage here, allowing spring growers to harvest and clear space for summer crops before heat stress becomes a problem.
Amadeus broccoli is grown for fresh harvest and consumption as a vegetable. The heads are cut and eaten fresh, steamed, roasted, or incorporated into any number of cooked dishes where broccoli's mild, slightly sweet character works well. Its quick maturity makes it especially valuable for spring planting schedules where gardeners want reliable production before hot weather arrives.

Start seeds indoors 4 to 6 weeks before your spring transplant date, germinating at 65 to 75 degrees Fahrenheit. Johnny's reports an average of 850 usable plants per 1,000 seeds, so account for typical germination rates when calculating your seed needs. Transplant seedlings outdoors once they've developed true leaves and nighttime temperatures consistently stay above 50 degrees Fahrenheit.
Transplant seedlings into the garden after hardening off for 7 to 10 days. Space plants approximately 18 to 24 inches apart in rows 30 inches apart, allowing room for the compact growth habit to expand without crowding. Transplant into soil that's been enriched with compost or aged manure, and water well immediately after planting to settle the soil around roots.
Harvest Amadeus heads when they reach full size but before the individual florets begin to open or yellow. Cut the main central head with 5 to 6 inches of stem attached, using a sharp knife at a slight angle to shed water. Many broccoli varieties, including compact types like Amadeus, will produce smaller side shoots after the main head is removed, extending your harvest window over several weeks if left in the garden.
