Most alliums including Garlic, Shallots, Onions, Leeks seem to get left alone by critters in my garden although the squirrels can be a problem with the garlic in the fall when they are digging in the beds to bury their nuts. I now put chicken wire over the garlic beds after I plant the cloves to prevent the digging in the fall and I leave them on to hold the mulch in place until the garlic starts to grow in March. Brassicas like Broccoli and Brussels Sprouts are also left alone by the 4 legged critters in my garden but I hear that ground hogs seems to really like them.

Yes, if your brassica are hit it had to be ground hogs. Right now outside the fence I have turnip, daikon and bekana. Note, here the soil has no iodine, and all brassica have iodine blockers so I think it is toxic to them. In a place with abundant iodine they (rabbits and deer) may change their mind. Don't know why the ground hogs are immune.

The same beds later will be planted with garlic, overwintering onions, and potatoes in the spring. I also have chinese garlic, chives, sorrel, sage, mint, oregano, and parsley out in the open. Also in the past I have had a single episode of a ground hog eating the onions.

If you want to expand further, there are lots of options in the brassica family, some of them even decorative, such as flowering cabbage.

edit: forgot eggplants. They, too, do well outside the fence and are decorative. Spinier varieties may be preferrable.

Nothing seems to have any interest in my globe artichokes.... except the aphids and ants.

Peter, how long does it take for the artichokes to bear fruit and do they last more than one year?

It took all summer for them to head out - late August. I didn't think it was going to happen.

They can last more than one year and produce an abundant crop the next year, but it is unlikely in our climate AFAIK. They are a lot of work, needing to be started indoors in early February and set out early for vernalization but after frost... kind of a challenge.

Something ate all my broccoli one year. I saw rabbit poop around the garden so I assumed it was rabbits but I guess it could have been something else.
