Skywalker Organic cauliflower seeds are?CERTIFIED ORGANIC!?This hybrid cauliflower is perfect for late summer or fall harvests. It’s a big, hefty variety with large leaves that partially wrap the medium sized heads. These are densely packed with tight, withe curds. The plants are uniform and well adapted for growing regions across North America. In our field trials, the large plants all matured at the identical rate so harvest was very simple. For the home gardener it might be better to plant three or four short rows at two to three week intervals so the crop doesn’t come all at once. Skywalker is cold tolerant and resistant to Fusarium Wilt and Fusarium Yellows.
