It produces large, densely curded heads up to 12 inches across in just 65 days, performing where temperature swings would devastate lesser varieties. This frost-hardy cultivar thrives in full sun with moderate water and soil pH between 6.5 and 7.5, making it a dependable choice for gardeners in zones where consistent summer heat isn't guaranteed.

Rober's real strength lies in its adaptability to temperature fluctuations that typically cause cauliflower crops to bolt or ricket. Baker Creek's team harvested flawless heads during a punishing Missouri summer, a testament to this variety's resilience. The tight, uniform curds form quickly, 65 days from transplant to table, and reach an impressive 12 inches without requiring obsessive environmental control. For gardeners tired of fussy cauliflower varieties, Rober combines productivity with genuine ease.
As a fresh eating cauliflower, Rober heads are roasted whole, cut into steaks, or broken into florets for raw platters. The tight, dense curds resist browning during roasting and hold their structure well in braises and curries. Storage potential makes it suitable for both fresh use and preservation through freezing.
No timeline data available yet for this variety.
Start seeds indoors 4 to 6 weeks before your last spring frost, maintaining soil temperatures of 65 to 75 degrees Fahrenheit. Seeds will sprout in 7 to 10 days at optimal warmth. Sow at a depth of 1/4 to 1/2 inch in seed-starting mix.
Harden off seedlings over 7 to 10 days of gradually increasing outdoor exposure. Transplant when soil temperatures reach at least 50 degrees Fahrenheit, spacing plants 18 inches apart. This frost-hardy variety can tolerate light frosts, making early spring transplanting less risky than many brassicas.
Cut heads when they reach 10 to 12 inches across and the curds are tightly packed and firm to the touch, typically 65 days after transplanting. Use a sharp knife to sever the main stalk just below the head, leaving a few wrapper leaves attached for protection. Morning harvest, when heads are cool and crisp, yields the best quality. Secondary side shoots may develop after the main head is harvested, extending the productive season.
