Sulfur containing winter greens

The most hardy winter greens in my garden are mostly rich in sulfur compounds including various onions (Allium) and onion-tasting brassica, Garlic mustard (løkurt), Alliaria petiolata or is it just coincidence that Alliums and Alliaria are both very hardy. 
Does the sulfur play a role in giving these plants hardiness? The only other plant that I can harvest a little of in midwinter is Hablitzia tamnoides (although it turns red in the coldest weather).

Allium cernuum also stays green through the winter and can be harvested even in the coldest weather!

Garlic mustard (løkurt), Alliaria petiolata is a short-lived annual / biannual that germinates in the autumn here and the leaves often make it through the winter and can be eaten in midwinter!
