I've done brassicas plots every year for close to 20 years now in northern WI. They are always eaten to the dirt come spring. Deer will hit the dwarf esex rape and radish as soon as they come up. Radish is really good thru bowseason. Kale and dwarf is a favorite for late bow and gun. Purple top turnips leaves are the least preferred but are still all eaten, but the bulbs are highly preferred late season and provide alot of food come January and February. I usually try a new brassica every year ( Winifred this year) but so far these are my favorites. I've tried most of the hybrids. They are all decent but still like the others better.
