Question:
The AP and New York Times style books do not capitalize "brussels" in sprouts, but what about Swiss chard? With careful chefs deleting spinach as an ingredient from their menus, this question is, well, cropping up. Capitalizing the Swiss in chard feels right to me, but I wonder what the strict grammarians say.
Answer:
If you look the vegetables up in the ONE LOOK DICTIONARY SEARCH
http://www.onelook.com/ you'll see that almost all dictionaries capitalize Swiss chard, while about half of them capitalize Brussels sprout. Both are obviously proper names and deserving of a capital S and B, respectively. I suggest that the reason for the anomaly may be that the sprout entered the language about 300 years before the chard-- time enough for it to become a common noun among the hoi polloi. If there is a more definitive solution to the conundrum, I am unaware of it.
